Yes, this appears to be the same problem, given the stack trace you supplied. Darrin On Feb 8, 2012, at 1:07 PM, Martin Baker wrote:

I'm seeing a hang too in FCPX 10.0.3 release. We have a filter with 12 parameters, one of which is a popup "preset" menu that in parameterChanged sets the values of other parameters. It worked fine in 10.0.2 but 10.0.3 hangs when you select one of the presets. Plug-in works fine in Motion 5.0.2.

Is this the same issue? Crash report log is enclosed.

That shouldn't make a difference. I think the only SDK updates were sample code updates.

Well this is frustrating.

Using the "performSelectorOnMainThread" trick Nathan mentioned I got my custom UI "working" with FCPX 10.0.2. Sent it over to a machine that has 10.0.3 and it hangs while setting the parameters again. Tried it both inside and outside an action block.

I'm still using the older FxPlug SDK though. Would that make a difference?
