By default, an Xtext project plugin puts its DSL-specific preference pages under the preference page named Xtext Languages. I can override this by editing the UI plugin's plugin.xml, but the empty Xtext Languages preference page remains, which is annoying. I want to hide it, but only if it has no child preference pages contributed by other Xtext plugins. It would be nice to make this possible.

Reproducible: Always

During the last iteration Sven had a look into this and wasn't able to find a non-programmatic solution. Since this is not what we wanted to achieve, we are running out of ideas at the moment.

I will reschedule this bug to no milestone and mark the bug as "help wanted".
Comment 2 Tom Seidel CLA 2009-11-05 08:56:23 EST 
A possible solution could be writing a XSL-Transformer Hook, checking if there are preference pages under the "XText Languages". If not this contribution can be supressed within this Hook.
Comment 3 Sven Efftinge CLA 2010-01-21 06:07:06 EST 
As the examples are now no longer installed, the preference page isn't polluted anymore. I'll remove the common "Xtext Languages" preference page all together, so that a language get's its own top level entry.
