NI_IMAQ IEEE-1394 bug?

[WNM]

I am starting to familiarize myself with the new v2.0 IEEE-1394 firewwire camera driver VI's and have been working with the property nodes that have replaced the IMAQ1394 Attribute & Attribute Inquiry VIs. I have managed to build a VI that will quite repeatably crash LabVIEW.

It requires:
1) a query of a camera attribute property that is recognized by the property node but not by the camera.
2) a subsequent query of another camera attribute property.

Has anyone else seen this?

An example (for LV 7.0, IEEE-1394 v2.0.0) is attached.

Hello Warren,

Thank you for using our discussion forums. I have taken a look at your VI and seen similar behavior as you described. I noticed that if you remove the bundle by name from the case structure the problem seems to disappear, let me know if you see a similar behavior. Otherwise, I am trying to investigate the problem and will get back with you as soon as I have any updates. Thank you for your patience and have a great day!

Sorry, but I had to get on with the job at hand so I uninstalled v2.0 and have dropped back to 1.5.3.
I am relieved to hear that you could duplicate the problem. I have submitted it as a crash report (Reference #7073374). I look forward to having it fixed because 2.0 provides better access to the camera's features & information.
