Hi,everyone.I got a problem when I implement a RCP app.

This RCP is based on a big xml data.And all the GUI controls will be
created and layout based on this xml data file.
When user open this xml data in app,several tab pages and several panels
will be created and layouted.
However a problem is always raised out when I open this xml data in the
5th time.It means the 1th-4th time I opened is no error.The exception is
"No more handles".However I disposed all the dynamic control each time
when I reopen the new page.I dont know how to catch the problem.

who knows?

It looks like you have a leak when you create widgets.
You should use the sleak plugin available on the SWT web page.
http://www.eclipse.org/swt/tools.php

Install it and check what resources are left behind when closing your pages.
