Debugging 365 using the info class

 A good and often used trick to use when hunting down bugs is putting a break point in the info class in the method add() and examining the call stack when an error is thrown causing the add method in the info class to be called for updating the infolog.

However sometimes when you are debugging in Visual Studio the debugger will not load the symbols needed to debug in the info class.

In the old days you had to resort to the very slow "Load all modules, unless excluded" under Debugging / Symbols / Automatic symbol loading preference, which would load symbols for ALL modules.

A neat addition that Microsoft has added to the Dynamics 365 FO/SCM extension for Visual Studio (can't remember from what version at the moment), is that you can now debug with "Load only specified modules".

So when you encouter that the debugger will not load symbols for the info class do this:

1. Choose Options in the 365 Visual Studio extension
2. Go to Dynamics 365 / Debugging
3. Put a checkmark in "Debug items in the solution and items in specific packages."
4. Pick what modules you want the debugger to load symbols for (In info's case ApplicationPlatform):


5. Re-attach the debugger to the World Wide Web Publishing service

Now the debugger will only load symbols for the selected modules, and since you've included ApplicationPlatform, symbols will be loaded for the info-class, allowing you to debug by stopping at your breakpoint in the info.add method.

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 ...

Subtle but important difference between _ds.executeQuery() and ds.Research()

This is actually an old entry. Been tumbling with a problem for the last few days. A form in our Dynamics AX module for Preventive Maintenance Control was not behaving. The form has "explicit" filter fields that the user can see without having to activate the form filter (CTRL+F3), for setting up filters most commonly used in an easy way. And this is working ok. However at this customer site, the form has been adjusted so that the user can have the form refreshed automatically periodically, and when the users at the customer site were making use of the "explicit" filter combined with the AX's normal filtering (CTRL+F3), the form simply threw away the normal form filtering. I discovered a subtle but very important difference between writing _ds.executeQuery(); (which was the way our code was doing it) and _ds.Research(); The difference is that _ds.Research() will retain the filter ranges in the forms query as they are right now. _ds.executeQuery() will NOT. It ...
