Description

If you filter on a category field in trackers, you cannot edit any viewed tracker items. The system returns a SQL error because filterfield is set, and filtervalue is null. If you filter on other fields, you can save, with no errors.

I have traced the problem to the calling of trklib->list_items (this holds the query that fails). This function is used to call and order the other tracker items for easy pagination of the filtered tracker items after a save.

However, the real problem is that $_REQUST'filtervalue' and $tryfiltervalue get lost in tiki-view_tracker_item.php when the save submit action is done on the form. Other URL query parameters appear to be stored as hidden fields on save action in tiki-view_tracker_item.

For whatever reason, non-array filtervalue fields (e.g. plain text fields) are remembered and thus the pagination and call to list_items works just fine.

However, when there is an array filtervalue (like there is with category fields), then filtervalue gets lost on the save action, and the save fails on a malformed query.

Solution
Look for $_REQUEST'cant' - if set, then skip listing all items. A bit of a kludge, but should work.

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.
