[TYPO3-dev] Question concerningcCustom treeview

[Andreas Bulling]

| and add the hidden field to the thumbnail view
| 
| $thumbnails.=$treeContent.$treeViewObj->hiddenField;

YEAH, thanks _a lot_! That was the reason for the problem - I overlooked
that small part... :-) 

In the meanwhile I figured out how to show the preselected category in the
left <select>: Setting maxitems to 2 (I don't know why but it works).

Thanks again,
  Andreas
