ADF 12c Table CRUD Fix for Auto Focus

I had a post about how to improve user data entry for ADF table with auto focus for new row - Improving ADF UI Table CRUD Functionality with Auto Focus. If you follow comments thread for that post - you will see described approach doesn't work exactly as it should in ADF 12c (focus is set for new row but later is lost after tab navigation - it should move focus to another column). Thanks to the community we have simple fix for this issue, read OTN Forum thread - Set Focus on CreateINsert row in ADF Table. I hope Oracle will fix this functionality in the next ADF versions (currently they say it is expected behaviour, and I don't agree with this). But for now - fix does the job.

 Sample app was updated to and it contains fixes described on OTN Forum - Focus is set for first column of new row to avoid extra mouse click:

After tab is pressed - focus moves to the next column:

Fix simulates row selection through ADF JS API. After focus was set for the first column in current row - we execute row selection based on active row key. This allows ADF Faces to move focus to the next column on tab, because it knows currently selected row on client side:

Make sure to set active row key in the bean method, same place where focus ID is calculated (otherwise there will be JS error):
