Hi,
I opened an existing FB5 project with FB6 and I get the following in the messages tab:
WARNING Action class : "TListIteratorAction" is not loaded and is referenced by this project, if you save this project the missing actions will be deleted from the project
(To correct the issue, go to Tools -> Package Manager and ensure the relevant action package (.bpl) file is loaded and enabled.)
My Queue Define and Push Items Queue actions appear, but my existing Queue Iterator action and it's children dissappear. I can add a new iterator and it works fine, but existing iterator is lost.
