April 2024
We upgraded! What's new? Learn more about new features, technical changes and solved bugs in 4App Multi Module Tree.
Note on upgrading: If you skip a version when upgrading, check all release and patch notes in between for important information. They apply cumulative.
Note on individualization: If your 4ALLPORTAL is highly customized or if you installed individual apps, please contact your implementation partner before upgrading. We recommend checking your custom contents, especially layouts and object renderers, carefully after an upgrade.
Breaking Changes
Major version 2.0 contains breaking changes and important upgrade instructions that should be read carefully.
# Breaking Changes
# Renamed Parameters sortBy to sortField
Layout parameter sortBy and MultiModuleTreeActor parameter sortBy were renamed to sortField.
What to do: Make sure to adjust these parameters in your custom layouts to keep them working.
# RootFilter Editable Parameter Now
For PID modules without any relation and with any descendant of the DefaultMultiModuleTreeRootLoader, we added new editable layout parameter addTreeRootFilter. In previous versions, the root filter was automatically set.
Please note: Per default, this parameter is set to "false".
What to do: To prevent each element from being displayed at root level (for trees without relations), you need to activate addTreeRootFilter for the root loader actor.
