Arduino IDE v1.8.9, esp32 v1.0.2 and ulptool v2.3.0

Arduino logo

Are you messing with ultra low power esp32 code and have tried to setup the ulptool example from duff2013s GitHub in Arduino IDE v1.8.9 with Espressif Systems esp32 v1.0.2?

Maybe you got a lot of strange compile errors like these?

Traceback (most recent call last):
 File "C:\Users\<your user name>\AppData\Local\Arduino15\packages\esp32\tools\ulptool\src/esp32ulp_build_recipe.py", line 506, in 
 main(sys.argv[1:])

 startupinfo)
 WindowsError: [Error 2] The system cannot find the file specified
 exit status 1
 Error compiling for board ESP32 Dev Module.

Note: This error is also reported here: https://github.com/duff2013/ulptool/issues/35

It is quite a simple fix: The error is probably caused by Espressif Systems moving around some files in esp32 v.1.0.2 – or actually renaming a catalog.

You just need to edit a single file in ulptool v2.3.0. Simply open your platform.local.txt file and change the line:

compiler.ulp.path={runtime.tools.ulptool.path}/esp32ulp-elf-binutils/bin/

…to…

compiler.ulp.path={runtime.tools.ulptool.path}/bin/

…and you are “back in business” :-).

Broken AL in Visual Studio Code October 2018 release (1.29)

Visual Studio Code logo

October 2018 release (1.29) for Visual Studio Code was just released, but unfortunately it breaks the possibility to publish AL extensions to your Dynamcs NAV / 365 Business Central.

Don’t blame the guys behind Visual Studio Code, this one is probably on the AL extension guys.

Only solution i know is to downgrade Visual Studio Code to the September 2018 (1.28.2) release or earlier for now, but I’m sure it will be fixed in the next CUs for NAV/BC.

The symptoms of this error is:

  • When publishing you don’t get any output in the VSC DEBUG CONSOLE. Only the OUTPUT shows the “normal” behaviour.
  • The Web Client won’t start after the publish.
  • The extension is not published if you start Web or Windows Client manually and check.
  • Your Windows Event Viewer will have several errors from your NAV Service tier with lots of call stack for each attempt to publish. The important text to search for is errors like:
    • Message (InvalidOperationException): RootException: InvalidOperationException
      This operation cannot be performed after the response has been submitted.
    • Message Failed request — Method:GET; Url:http://localhost:7349/NAV130_GSL/dev/metadata; StatusCode:InternalServerError; ReasonPhrase:Internal Server Error; Token:
    • Message (InvalidOperationException): RootException: InvalidOperationException
      Dynamic operations can only be performed in homogenous AppDomain.

The missing AL language support for VSC October 2018 release (1.29) was mentioned very briefly at NavTechDays 2018 in one of the first sessions (forgot which one), but I’ve not been able to find it on Google, so that is why i provide this blog post.

These kind of errors is almost impossible to trouble shoot if you cannot Google them :-).

Hint: Visual Studio Code will auto-update to the newest release automatically. To disable this, go to File/Preferences/Settings and change the “update.channel” to “none”. I highly recommend that you return this setting to its original value when the AL-language guys fix this error.

Cent and Yen in Dynamics NAV 2018

Microsoft Dynamics NAV logo

If you run a Danish Dynamics NAV and get objects from outside Denmark, you might experience the Danish letter ø/Ø beeing replaced by ¢/¥ (the sign for Cent and Yen).

The fix?
Simply export all your objects as text, run them through the following powershell and import them again.

(((Get-Content -encoding Oem "InFile.txt") -replace ([char]8250),([char]251)) -replace ([char]157),([char]238)) | Set-Content -encoding Oem "OutFile.txt"

 

Finish off by a compile and syncronize all tables.

This is off cause on your own risk, so start by taking a full backup of your NAV system/server.

2018-12-20 Updated: powershell improved and now using unicode values of chars

My Dynamics NAV App is FUBAR (updated 2018-06-22 with new solution)

Microsoft Dynamics NAV logo

For readers not knowing what FUBAR is, please see Wikipedia.

If you Dynamics NAV 2018 service will not start (or actually shuts down immediately when you try to start it), and you get something like this in your Windows Event Viewer (App Name, object ID and/or Name can probably be different ones):

Message: <ii>An error occurred while applying changes from the 'Payment and Reconciliation Formats (DK) by Microsoft 1.0.20348.0' app to the application object of type 'PageExtension' with the ID '13623'. The error was: InvalidOperationException - Metadata delta application failed due to the following error(s): The metadata object IncomingDocAttachFile was not found.</ii>

…your installation is FUBAR (or at least I don’t know how to repair it easily).

PowerShell cannot uninstall/unpublish the App when no Service Tier is running – so that is not an option.

Also I was not able to Google a solution, but here is what I did to make the service tier run again:

  • Take a fresh backup, and make sure nobody will open NAV until you say OK (it will be possible as soon as we get the Service Tier running again).
  • Export all your objects to text and locate (search for) the (probably page) object with the metadata object that could not be found (i.e. “IncomingDocAttachFile” in my example). I found it in Page Object 25.
  • Export the (Page) Object to a FOB-file (just so you have it).
    Overwrite/reimport the (Page) Object from a backup without your latest changes (be warned – if this is a table object, this will empty the table – so make sure to preserve the data somehow).
  • Redo your changes to the object without messing with the metadata object that could not be found (i.e. “IncomingDocAttachFile” in my example.

Test that everything is ok, before letting anyone work again.

NOTE: I’ve not tried this with a table object, only a page object – so I’m not even sure this error can occur on tables?

DISCLAIMER: This is probably unsupported by Microsoft and you should do this on your own risk. We will not be responsible for any problems, data loss or down time etc. you may discover/experience following this procedure, or after doing this procedure. You are on your own here – but hopefully this will help you and save you the effort of finding a solution yourself! 🙂

2018-06-22 I did’nt quite nail the solution first time around, as the problem creped in again. So I change the solution to the right one 🙂

“SQL Server does not exist or access denied” using Windows 10, build 1803

Microsoft SQL Server logo

If you are running your Microsoft Dynamics C5 or Microsoft Concorde XAL program files off a SMB1.x share, and your client is running Microsoft Windows 10, your C5/XAL might stop working if you upgrade your Windows 10 to build 1803.

This is really a “far out” bug, in build 1803 Microsoft apparently strengthened some security which makes it impossible to connect to a SQL Server through ODBC if – and only if – your program files are stored on a file sharing running SMB1.x (which means it will actually work if you copy your program files to a local drive – but that will off cause break things – some C5 and XAL files needs to be shared!).

And now we’re at it – this is not only hitting C5 and XAL, but other systems using ODBC as well: https://www.google.com/search?source=hp&ei=zfH6WqasBorGwQKImqroDw&q=sql+connection+problem+after+windows+update+1803&oq=sql+connection+problem+after+windows+update+1803

The solution is straight forward: make your file share run SMB2.0 or newer:

Hint: If you run this PowerShell command on your client, it will list all your network shares and the SMB-version in use for each of them:

Even Microsoft gets this wrong :-)

Microsoft Dynamics NAV logo

In Dynamics NAV events are also fired on temporary records – this is really a confusing design and can trigger various, hard to debug, but rather serious issues.

On one customer running NAV 2018 CU1, user group memberships was cleared randomly. We did’nt know exactly when, but in the end one of my Indian colleagues figured out it happened related to the “Export to a datafile” functionality.
I was pretty sure someone was doing a DELETEALL – but was it in our code or in the standard code? And exactly how/where?

Actually it was easily found.
I created a subscriber one the delete trigger in table 9001 / User Group Member – only with one line of code:

ERROR('STOP');

…and started the debugger.

Note that events are fired even if the table trigger is not executed (i.e. INSERT/DELETE/MODIFY/RENAME is called with FALSE).

The deletion of the group membership is caused by the select/deselect all companies on the “Export to a Datafile” page in NAV. The list of companies is build in a temporary company record and DELETEALL is used on it when you select or deselect the all companies flag.

Unfortunately there is a subscriber in Codeunit 2 called OnAfterCompanyDeleteRemoveReferences which does not check if it is actually called with a company beeing removed, or just called with a temporary record instance from somewhere.
So it cleans up anyway – removing actual reference data from still existing companies!

This shows very clear that non-self-explanatory functionality like events beeing called on temporary records should have been avoided by Microsoft when designing this.
After all the goal of the development environment and -language should be to help developers write correct code – not to trap them into creating bugs.

If I had to redesign this functionality I would make it an function trigger property (default off) if the subscriber should run on temporary record instances.
Or at least let a subscriber parameter tell if it is temporary or not (not that this would make it easier to check, but it would remind you about checking it every time you created a subscriber 🙂 ).

To me the current functionality is wrong, people are getting bitten by this. It is illogical design and even if you tried it once or even multiple times (and my guess is that you have if you are writing event subscribers), you’ll probably forget it and do it again in the future.

At least we know we are not alone – Microsoft C\AL developers are actually also getting bitten by this :-).

Please note – this bug is not only emptying the 9001 / User Group Member table, but other tables as well: User Group Access Control, Application Area Setup, Custom Report Layout and Repor tLayout Selection.

By the way: The correct fix (introduced in NAV 2018 CU2) is to make these lines the first two lines in Codeunit 2, OnAfterCompanyDeleteRemoveReferences:

IF Rec.ISTEMPORARY THEN
  EXIT;
