Re: Focus problem in Button Field

Default behavior for all managers is focus on the last field in the their list when focus comes back to them, and the first on the list when focus moves forward to them.  So by carefully using the managers you have, you might be able to manage the focus movement you want.  Alternatively you will have to override the focus behavior for the manager to set the focus where you want to be. 

 

There are other posts that talk about this, specifically for HorizontalFieldmanagers.  Have a search of the forum and you will probably find someone else has tried to do something similar.  You will need to look at onFocus and moveFocus.

 

Alternatively, you might find the that TableLayoutManager will layout your Fields without requiring multiple Managers and focus will move as you want.  You can find code for this manager, in the following KB Article.
