[rules-users] Rule Templates

[FrankVhh]

Hi,

After trying the example from the documentation, eclipse returned the same
error. So, I got the same idea and just worked further ignoring eclipse.

I saw what I saw and that was that it works fine now, even with the error
still displayed in the problems view.

Thanks for the help ;-)

Regards,
Frank
