You guessed right. I'm not using the submit button. Not validating text.
I tried your suggestions but could find no luck.
- Created a button independent of the TEB. Initial state is hidden.
Created the empty (null) variable.
- Setup advanced action for TEB On Success. The action compares text property of the TEB with null. If not equal then the button is shown.
When I run the interaction, if I type some text into the TEB, because the TEB text variable updates in realtime, and is immediately not equal to the null variable, I would expect the button to become visible. It does not.
What am I missing?
