Bug 148611 The edit parameter dialog hang up in my case.
Reproduce: The attachment include a library and a report. 1. Put the library file under the resource folder, "D:/Actuate/BIRTs/200606260630/eclipse/plugins/org.eclipse.birt.report.designer.ui_2.1.0.N20060624-0630/resources/" in my application. 2. Open the report, preview in the embedded viewer. 3. The Edit parameter dialog hang up. (Notice: it is the extened "dynamic" parameter that cause the problem. My CPU reaches 100% ocuppation when rendering the dialog, while when I end up closing the dummy dialog, CPU doesn't seem to be released, still 100%. )
