A little trick: suppose you want to add a special column which will display a label (the same in every line), and contain an "action url". An example could be a listbox allowing you to quickly download and delete files:

or plenty other things.

The best way I found to do it is the following:

• add a listbox column file_download_url|-
• make it an editable column (by adding the id to the "editable columns" box
• to the form add a LinkField listbox_file_download_url
• make it non-editable
• set its title in TALES tab to something like python: here.Base_translateString('download')
• set its default value to a TALES expression using cell variable (it represents the object which is displayed in the listbox line

This is it - if somebody knows a better way, write it here.
