[platform-dev] setting the wait cursor does not work

[cccp14]

Hi, i am asking for your help.

In netbeans platform app, I have a dialog created by DialogDescriptor:


now I want to execute a task like this:

getExportSettings has a section that takes a few seconds to execute.
While this is executed, a want to show a wait mouse cursor. I found this:
http://netbeans-org.1045718.n5.nabble.com/Setting-wait-cursor-td3026613.html#a3026614
setting wait cursor where is a code to set the cursor.

But this does not work, if it is as shown in that link. The cursor will not
change. But if put a code for showing messagedialog in the "run" section of
that code

, after the closing of messageDialog (the task still executes) the cursor is
correct! I dont get it why it is performing like this, can you somehow
explain it or help me to achieve the correct cursor without messageDialog?
thanks
