PlatformCustomSoftwareInputPanel: - aviable for TextField but not for TextArea ?

[redex]

Hi!

I wan't to create a customized virtual keyboard with only 6 Buttons for a Multiline Textbox.

There is a very useful property at a single Line TextField called platformCustomSoftwareInputPanel.
I'm able to define there a own Component with the Buttons I need. Very comfortable.

Sadly TextField provides only a Single Line Textbox. But I need Multiline like at TextArea. But sadly there ist the property platformCustomSoftwareInputPanel missing.

Is this a bug, am I making something wrong? Any hints?

Kind regards,
redex
