I'm using TDBAdvMemo 2.3.3 and actionlist, and I believe I found a bug.
Drop a Dataset and Datasource and link them to a COnnection/database/table/
Drop an ActionList, create 2 actions : DatasetPostAction and DatasetCancelAction
Drop a TPageControl,
create a TabSheet.
Drop a TDBAdvMemo on that tabSheet, and link the memo accordingly.
Drop 2 Buttons
Link each button to an action.
Run you project. Modify the memo, the buttons won't be activated.
Place the memo on the form and it will work correctly.
Can you duplicated it? Is there a work around?
