May I control menu when I launch the 'ExportController' plug-in?

Hi everybody,

I have write a 'ExportController' plug-in based on the sample SDK(Mac) provided.

It works correctly as expected workflow, a new sub-menu under 'Export' added, and it can render timeline, export it, and do other post-process.

But it does not support 'copy', 'paste', 'cut' operation for NSTextField in my custom UI.

I found all menu items' status didn't change, and the items(Copy, Paste,...)  under 'Edit' are disable.

I think the copy function missing is because menu item disable, but I don't know it is support to change or edit those status?

(I am using the Premiere Pro CC Mac SDK, plug-in type is 'ExportController'.)

Thanks,

Iris
