UMG: no "Expose on Spawn" for Text variables?

When creating Blueprint Widgets, I can mark editable variables as “Expose on Spawn” so I can fill them when creating the widget, before the Construct event is dispatched. But the option is not available for Text variables, is there a reason for that? This is very inconvenient since I’m creating custom widgets like buttons and alert boxes and cannot pass their text in their constructor.

– EDIT –
This is clearly a bug: I temporarily changed the variable type to String, enabled “Expose on spawn”, changed it back to Text and the variable was correctly exposed on the Create Widget node.

Yup, wasn’t a thing anyone had tried to expose on spawn before in blueprints until UMG. Has been fixed for 4.6.

Cheers,
