Description

When the TRACKERITEMFIELD plugin is called trying to access a tracker item which does not exist, a fatal error like the following occurs:

Objects which contain such calls cannot be viewed, and reindexing for search is also broken.

This happens since r37583 and persists in trunk r68584.

Solution
This needs a modification in wikiplugin_trackeritemfield.php to display a "Tracker item does not exist" message, but there's surely something which could be improved in Tracker_Item::fromInfo() too. That function should throw an exception making the problem clear, not return a bogus object.

Keywords

The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
