Ca this be addressed in a future enhancement?

I'm not yet sure there needs to be an enhancement, or what it would be.

I noticed in your partial example that you are attempting to set focus to particular dropdown items using HasFocus. Now that you understand that HasFocus is not used for that, have you tried an example where you set the dropdown to null, and use HasFocus(TRUE) once. That works for me. (But I'm only attempting to use HasFocus on one element on the form, in accordance with the documentation)

Yes I did change that yesterday after you steered me correct on the other issue. Same problem.

I think you should be able to set up a similar example that would be simpler (no DB) by just using 1 field as dropdown (a,b,c, etc) then after select rebuild (like Bill, Bobby, Betty, etc) the drop down values (set .items to null first). and redisplay the form (NOT as NEW) to duplicate it.

Ok Mark here is a test for you to copy on this issue:

Program to invoke LrBugDrv

When you run this example click on the first drop down and select a letter (any besides select ...) and then click the 2nd button dd drill test. It should reload page and no expand the first drop down even though the code sets focus on it.

Note that if you click into dd 2 and select before clicking the dd drill button that the dd 1 will expand.

Which brings me back to where I started this thread. How can I force a refresh on a dd that already has focus so that the dd is expanded?

The first component is added twice, I think.

I need a component with a uMakeLabel method.

Sorry I fixed them. All are updated as I am still trying to duplicate the dd to label error
