Valid length of a form field label

AX sometimes surprise you. Such surprise often make you chase a wild goes all day to reveal it was just a dead rat :@

This just happened with me but all to reveal something I don;t think would be available on internet

Try these:

  1. Find or create a label with 250+ length. 
  2. Assign this label to a form field (not static field or any such control)
  3. Open that form
  4. Your client just crashed
Why am I telling this to you at all is the fact that my client wanted me to put huge texts against form fields. Weird, but sometimes we face requirements about which client donot accept any consultancy or education, and we just HAVE to implement it.

Now can you imagine how wild those 400+ length labels made me work and search and find the clue why my client is crashing. I went through everything including full compile, sync, cache cleanup, .auc files, label file regeneration. I had to take every step due to the reason that evenvwr log was not much of a help in my scenario. I am attaching the log for your reference here;

Application: Ax32.exe

Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
   at Microsoft.Dynamics.Kernel.Client.ActionPaneInterop.ClickEventHelper.Clicked(System.Object, System.EventArgs)

Length for a field label (non static text control) is 250

Do you have an XPO so we can test this? I'm unsure if we create the correct code by following the 4 steps. (I'm not a developer :-)

Kind regards
