Bug 297152

Description Ian Trimble 2009-12-07 23:07:14 EST

Closing a Dynamic Web Project (with JSF facet) that is new in the current workbench session throws an exception. The issue involves JSF because when creating a dynamic web project without it, closing the project produces no exception.

To reproduce, after creation of a new dynamic web project, the JSFAppConfigManager must be initialized. One way of ensuring this is to create a new managed bean using the new managed bean wizard in the Faces Configuration Editor. (The managed bean name is validated as unique by calling the JSFAppConfigManager.)

Current thinking is that the JSFAppConfigManager locator that reads web.xml context parameters is not cleaning up correctly (the EMF resource that causes the issue is definitely a WebResourceImpl, and this locator is the only component of JSFAppConfigManager that reads web.xml).
