Cannot read property 'mthREMOVEFIRST' of null

[eddie9394]

I am trying to close the framework command window after a delete operation. I had tried #COM_Owner, #COM_Self and #COM_Ancestor avCloseForm. All yield to the same error message below:

Fatal Error:
Cannot read property 'mthREMOVEFIRST' of null
Location:
Reusable Part: CMGEXCDetailCommand, line 945
Call Stack:
1. Evtroutine Handling(#zInt_AyncOperationsTimer.Tick): CMGEXCDetailCommand, line 945
Reported By:

Any suggestion?! THANKS!

Could you post your command handler code in text file?

[eddie9394]

Mark, Thank you for the reply. I created a simple command with just one button and the avCloseForm works fine, so something in my code is causing the issue. Here is my code please shine some light to it. Again THANK YOU!

Found my problem! The #COM_OWNER.avCloseForm have to be completely out of scope of the Save.Completed and the avExecuteAsyncOperation

[MarkD]

So did you trigger its execution on a short delay timer?

[eddie9394]

Yes, did it with a timer. THANKS for your support!

[MarkD]

This will be simple in the next version ...............

#Com_Owner.avCloseForm has new optional Delay() parameter
The Delay() parameter may be used to delay the close operation to allow already stacked or scoped operations to completed first.
The value specified is in milliseconds. The default value is Delay(0). Values <= 0 mean no delay is used.
