B4J Question [ABMaterial] ABMInput: how to change backcolor when the input has focus?

[Cableguy]

Hi ABM gurus
I guess the title explains it all...

I have an Input field, and I just can't figure out how to change the BackColor when the input is focused..
For the fore color we have the FocusForeColor, but not the FocusBackColor!?

That does not exist in ABMaterial.

so, no other way to change the focused backcolor?
