Hi how to disable backButton in ActionBar?

appActionBar.backButton = new Action( 'Back', null, {id:'back'} );
appActionBar.backButton.enabled = false;

This work when is called before 

ab.addChild(appActionBar);
this.addElement(ab);

But when I call afer this button stays enabled i even try this:

ab.removeChild(appActionBar);
this.removeElement(ab);
appActionBar.backButton.enabled = false;
ab.addChild(appActionBar);
this.addElement(ab);

But no luck.

What happens if you:

appActionBar.backButton = null;
?

My guess is that would remove the back button.

Hi thanks, that worked, it's a workaround. 

null - removes button like you wrote, but I meed to disable button (action) maybe my code work but i need something to invalidate or render or update action bar  

but this is solution for now

It would be nice to disable actions, but I found that I just removeAll() and then add back what is needed based on the current state of the page. Not great, but it works. It what use case do you want to prevent the user to go back to the previous page?

I'm having similar fun with ActionBar.

And I also add/remove the backButton - e.g. since my screen requires an explicit Save...

I chose to enable/disable Actions, rather than adding/removing: I think it would be too confusing to a user when menu items keep changing places.  That said, I cannot get the menu items to appear in a consistent order even though I always add them in the same order.

All Actions are explicityly designated as being on the bar or on the overload and I've also tried addActionAt, but the menu items are placed in seeminly random order from one invocation to the next.

Suggestions?

Just to confirm. This works now.

appActionBar.backButton.enabled = false;
