Have you made sure to update your Runtime?

The runtime is used for rules validation through the IDE.

I hadn't done this because I wasn't aware that you had to - syntax
coloring was working, just not validation, so I wasn't sure what the
problem was.  However, creating a new Eclipse runtime has caused even
syntax coloring to stop working - now all I get is a plain text editor,
and still no validation.

These are the steps I followed:
<ol>
<li>Opened Window >> Preferences >> Drools >> Installed Drools
Runtimes</li>
<li>There were no Installed Drools Runtimes listed, so I clicked
"Add..."</li>
<li>Clicked "Create a new Drools 5 Runtime..."</li>
<li>Created a new folder under UserRoot/.eclipse/ called "DroolsRuntime"
and clicked "OK"</li>
<li>Selected the new Drools Runtime in the list and clicked "OK"</li>
<li>Restarted Eclipse</li>
</ol>

Thoughts?

I just right clicked and manually opened my rule file with the associated
editor and syntax coloring came back; however still no validation,
regardless of whether I use the .drl extension or .dslr extension.  the
.dslr extension does open in the DSL Rule Editor rather than Rule Editor. 
Manually right-clicking and clicking "validate" has no effect either.
