We had a recent update to the latest build on Lotus Notes 8.5.1 on Ubuntu. As usual the update appeared to go perfectly.
One of the new capabilities I had looked forward to was the inclusion of the Composite Application Editor (cae). The synaptic package name was "ibm-notes-cae".
When I created a new Composite application - I was given the instruction to use the ..."'Actions > Edit application' menu item to add content." Alas the "Actions" menu was not visible. First I tried removing the ibm-notes-cae package and reinstalling it, however this had no effect.
Ray Davies suggested I shut down Notes and rename the "workspace" directory within the notes/data directory and restarting the Notes Client. After a restart the "Actions" menu appeared and I could edit the composite app.
I did have to recreate the previous widgets I had been using - but that was not such a big deal - and I was back to work in five minutes flat.
Which was nice :-)
