Flash Builder not showing members of XML or XMLList classes
===

All of the sudden Flash Builder is not longer showing the members of the XML or XMLList classes for code completion. I did some experimenting by creating a brand new workspace with new empty projects (to make sure it wasn't some corruption in my main working set(s)), and it appears the bug only affects Flex projects; Flash Professional projects still work. 

The Flash Builder version is current (4.6), which is based on Eclipse 3.7.

A picture will show this much more clearly:

  - In a Flash Professional project: typing `.` or hitting `CTRL + Space` after the name of a variable of type `XML` brings up the member list:
    ![Autocomplete for Flash Professional project][1]

  - In a Flex Library project, only default `Object` members appear:
    ![Autocomplete for Flex Libarary project][2]

  - In a Flex project, only default `Object` members appear:
    ![Autocomplete for Flex project][3]

This morning I did install some updated components of the Eclipse Web Components for editing XML and XSD files...

I did review the various tips itn http://stackoverflow.com/questions/5826249/flash-builder-4-suddenly-stops-doing-auto-complete-for-some-classes but they don't seem to affect this situation -- particularly since it manifests in a brand new workspace with only 3 tiny projects.
