Event Handler/Create User Event bug

[m3nth]

This is a problem I've run into a few times on my system (Win2k) so I finally went back and reproduced it step by step since it wasn't too hard. It causes LabVIEW to crash and exit without saving.

- Create an Event Handler
- Place 'Register Events', wire output to dynamic event terminal
- Place 'Create User Event', wire output to 'Register Events'/User Event

- Place an Empty String Constant [""], wire to input of 'Create User Event'
- Set empty string property -> Visible Items > Label = True
- Rename label from "Empty String Constant" to other such as "Event"
OR
- Create a cluster constant with something in it
OR
- Place a boolean constant
- Set boolean property -> Visible Items > Label = True
- Name label something su
ch as "Event"

- 'Add Event Case...' to the Event Handler, select Dynamic / : User Event
- Delete the constant wired to 'Create User Event'.
- Place a constant of a different data type and wire it to the input of 'Create User Event'

LabVIEW immediately disappears (all changes are lost) and this error is displayed:


================================

LabVIEW.exe has generated errors and will be closed by
Windows. You wlil need to restart the program.

An error log is being created.

If there is a more appropriate place to post things of this nature that don’t really add to the discussion group, but need to be brought to the attention of NI, please post a URL or submittal method. Thanks...

Thanks for the detailed request. We are aware of this exact issue, and the problem was actually fixed for LabVIEW 7.0 for Mac/Unix. Unfortunately, it did not get fixed for the initial release of LabVIEW 7.0 for Windows, but we have plans to include the fix in the first LabVIEW patch for 7.0.

Also, the Discussion Forum is great for notifications of this kind. For future reference, you also have the options of emailing NI engineers directly, or calling us with suspected bug fixes, if you would like more direct communication.

Thanks again, and have a great day!
