Build Identifier: 20100617-1415

I have several scripts that have no file extension.  When I attempt to open them using the php editor I get:

"Unsupported content type in editor. To associate file extension with a supported content type, please see Content Type Preference Page"

I then attempted to add the full file name to the "Content Type Preference Page" and that gives me the following error:

Could not open the editor: org.eclipse.core.internal.filebuffers.SynchronizableDocument cannot be cast to org.eclipse.wst.sse.core.internal.provisional.text.IStructuredDocument

Stacktrace:

restarting eclipse allows for opening of the file in the php editor.  


Isn't there a way to allow for opening of a file in the php editor without jumping through the hoops of the content types?

Reproducible: Always

Steps to Reproduce:
1. right-click on a php file with no file extension 
2. select open with -> other
3. select php editor and click ok

result: "Unsupported content type in editor..."

4. Click linke to "Content Type Preference Page"

result: opens preference window to "Content Types" section

5. Expand "Text" under content types then click "PHP Content Type"
6. Click "Add" 
7. Enter filename and click Ok
8. Click Ok to exit the preferences
9. Double click on the file in the PHP Explorer

result: exception "Could not open the editor: org.eclipse.core.internal.filebuffers.SynchronizableDocument cannot be cast to org.eclipse.wst.sse.core.internal.provisional.text.IStructuredDocument"

No longer reproducible. The file can be opened in the editor.
