Thanks Bil for your reply.
I also try to get the context menu on the other cocoa apps, but the result is also fail. Even though I created a new app with TextFiled, I still can't get the context menu which pops from TextFiled. Is it by design issue? Do we have the other way to get the context menu?


Thanks,
Peter

GUI Scripting runs up against a bug in TextEdit. Technically, there is a mismatch in the accessibility hierarchy in this situation, where the menu knows it has a parent object (the text area) but the text area does not know it has a child object (the menu). You can see the menu in Apple's Accessibility Inspector and in UI Browser's screen reader because screen readers traverse the hierarchy from the UI element visible on the screen (the menu) up through parent after parent until they reach the application. GUI Scripting (and UI Browser's browser view) traverse the hierarchy in the other direction, from the application down through child after child until they get to the text area -- and then, because of the bug in TextEdit, they can't see the menu.

There is no solution until Apple fixes TextEdit. File a bug report. In the past, Apple has been very quickly responsive to my reports of hierarchy mismatch bugs like this.
