I have a pretty common problem with tables. I put a button in a table column. A "setActionListener" makes sure that the called action can access the id of the entity the column represents and the action can operate on that entity. The CollectionModel needs to be present before "model update" so that the actionListener can retrieve the data from it. In tomahawk there is the attribute "preserveDataModel" in order to persist the datamodel from request to request. Another option is the use of "saveState" component. I understand that loading the data freshly has advantages but in my case it might be pretty slow (Lucene query). Is there a way to do preserve the datamodel in trinidad?
