I'm using eclipse 3.6.1, and among other things have a few j2ee plugins and php.
In the content types (under text) both the jsp type and php type both have ".inc" in the file association.

The workspace in which I work with php is a different one than the one I'm using for jsp (or java for that matter) and so in the php workbench I defaulted the php editor to handle .inc files.

When I open a .inc file in the editor though all of the text is one big error (all red underlined) and in the Problems view all of the errors are from type "JSP Problem", also when I view the properties of the file I get Type: File (JSP).
