Form Templates replace TWikiCategory Tables from the 01-Dec-2000 version of TWiki.
Main Changes from Category TablesForm Templates more powerful, flexible replacement for the original TWikiCategoryTable. Data from existing category tables can be imported directly.
Importing Category Table Data | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Changed: | |||||||||||||||||||||||||||||||||||||||||||||||||||||
< < | On upgrading from the previous TWiki, a Form Template topic has to be built for each web that used a Category Table, recreating the fields and values from the old twikicatitems.tmpl . The replacement Form Template must be set as the first item in the WebPreferences variable =WEBFORM . If missing, pages will display, but attempting to edit results in an error message. | ||||||||||||||||||||||||||||||||||||||||||||||||||||

The new Form Template system should work with old Category Table data with no special conversion. Data is assigned to Meta variables the first time an imported topic is edited and saved in the new system.
NOTE: If things aren't working correctly, there may be useful entries in data/warning.txt .
