Action bar and buttons not visible to pre-8.5 Notes clients

Applications that I have developed on Notes 8.5 to 8.5.1FP3 work fine on 8.5 or higher Notes clients, but when those applications are opened by Notes 7 or 8.0.2 clients, the action bar and action buttons are missing from views. Is there an explanation and fix for this or am I forced to upgrade all the clients to 8.5?

Environment:

Server Domino 8.5.1FP3 on Windows Server 2003

Designer 8.5.1FP3 on Windows 7 Professional

NSF launch option: open in designated frameset, default view has Lotusscript shared actions in the action bar

Subject: compatibility

There shouldn’t be any issues with things like actions bars, but in general you should develop on the lowest version of the client that’s going to use your apps.

This is purely because if you use any functions that are in 8.5 but not available in the earlier versions of the client then there will be problems.

So, check the options you’ve used, if they’re not available in 7 or 8 then this could be your problem

Subject: Are you including System Actions?

8.5 has several new System Actions - everything after ‘Remove From Folder’. There is a known issue that older clients stop reading actions after the first unkown action. So any actions after ‘Remove From Folder’, including user created actions, will be ignored. This might be the problem.

If so, removing the new System Actions, or moving your actions before the System Actions, should fix the problem.
