Be careful - only do extensions of a table, that actually contains augmentation.

 Note to self.

Be careful of creating extensions to a table, that contains no augmentation.

I experience problems when opening the Released Products Forms on my developer box.

I got a run-time error "Object reference not set to an instance of an object" when opening the form. The error also occurred when changing records in the form, BUT strangely enough ONLY the first time the cursor arrived a at record. The second there was no problem. 

Researching a bit with the debugger, I could see that the error occurred at the super() call in the FormRun class, and in the active method on the EcoResProduct datasource.

I discovered that I by accident had created an extension to the table EcoResProduct that contained NO augmentation what so ever.

Double checking that the extension had not been checked in to azure DEVOPS, and that the xml-file for the table extension in 

K:\AosService\PackagesLocalDirectory\xxxxxDev\xxxxxDev\AxTableExtension

contained no augmentation, I deleted the extension in Visual Studio, compiled the whole model, and poof the error was gone.

Suppressing the infolog

Supressing the infolog is often useful in D365FO when augmenting code. When augmenting code using COC (Chain Of Command), you can have new code run either before or after the code you are augmenting. This means that any infolog-messages that the standard application code does, will be shown to the user, even if your augmentation supports a scenario where there must be no infolog-messages. How do you avoid the standard application infolog-messages ? To the rescue comes temporary supression of the infolog. The suppression consists of: 1) Saving the current infologLevel 2) Setting the infologLevel to SysInfologLevel::None 3) Run your code 4) Restoring the saved infologLevel to the infolog For example a table could have a validatewrite-method that validates that you are only allowed to use 3 out of 6 options in an enum-field, and you need to allow for a fourth one. Table a - validateWrite method: boolean validateWrite() {     Switch (this.enumField)     {     ...

Dynamics AX 2012 ValidTimeState tables and form changing view from current to all

Valid Time State tables are new i AX 2012 a gives the developer the possibility to easily create tables that hold e.g. current setup data for various purposes, and at the same time keeping a "history" of the changes of the data in the table. For more reading: http://msdn.microsoft.com/en-us/library/gg861781.aspx I was tasked with doing a setup table with rates for calculating Vendor Bonus and I chose to base this a valid time state table. The customer asked for a button on the form, where you maintain the vendor bonus calculation setup data, so you could toggle viewing "Current setup" or "All setup" records (changing the view from actual to all records and vice versa in the form). I found that you can not change the ValidTimeStateAutoQuery property on the form data source in a form at run-time. It simply does not change anything, so I came up with the following solution: A boolean class member in the classdeclation method of the form: boolean ...

ProcessGuide framework

I was tasked with developing a custom "process" for printing ad hoc labels in the Dynamics 365SCM WHS app. WHS process guide - development docs Reading the great articles from 1clickfactory (starting point  https://www.1clickfactory.com/blog/advanced-whs-mobile-device-development-part-1-process-guide-framework/) gives a good starting point. Especially Edgaras' tip on running  SysExtensionCache::clearAllScopes();  in a runnable class after introducing a new step/pagebuilder class combination  is VERY useful. And of course Microsoft's own documentation ( https://docs.microsoft.com/en-us/dynamics365/supply-chain/warehousing/process-guide-framework ) also helps. However, I wanted to chip in with a couple of things. Extending WHS base enums If you extend the WHSActivity, WHSWorkExecuteMode or WHSWorktransType base enums with new options it is a good idea to run a database synchronization when you are done with extending them. Otherwise you might be frustrated to find, th...
