Hi,
i found that in MODX 3, the
resourceArrayproperty of the controller can be undefined during theOnDocFormPrerenderevent in certain contexts. This leads to PHP warnings like "Accessing property on non-object" or "Undefined property".This PR adds a safety check for both the controller and the resourceArray property to prevent these warnings.
Thanks!
