Hi,

I have tried to modify the example from tutorial5 (database relations) by adding a description field(HTMLText) to the Module class.
Then, in the function getCMSFields_forPopup() I added the line:

$fields->push( new HTMLEditorField( 'description' ) );

Now when I go to a project page in the 'module' tab, and try to add a new module the popup form does not show the fields and I get a javascript error saying "f has no properties" (from tiny_mce code)

I have seen a similar discussion here
I really like SilverStripe, but this kind of problem is a show stopper for me.
