Hi, Horst.
I don't know if my adaptation in the Master Layout or not?
I just have this when I enter adaptation mode.
When I publish the changes, this pops up.
Sometimes, even after publishing the changes, those are not successful.After publishing, I just see an unchange screen even if I am the same user. When that kind of things happen, I just edit again and publish again. Then it works.
There is one more thing. My extension fields have their visiblity bound with indicators.
Should I do the adaptation before the binding or after? (I did both 
)
Should I do the adaptation with a business user(when I log in with this user, I can see other extension fields added by other users from other solutions) or with just my PDI user.(actually I am just doing with both )
But first, I do the adaptation with PDI user as soon as I have finished adding the extension fields to a standard screen in UI designer.
After making some changes in the adaptation mode, I publish the changes with the PDI user.
Then, I log in with the business user. I can see some changes are commited but some are not.
So, I just edit and publish the uncomitted changes again with the business user because I think the business user is the actual user who is gonna use this app.
Regards,
Fred.
