In Acrobat 8.x and 9.0, validation is not automatically performed when the user clicks the following type of form fields:
- text
- date/time
- numeric
- decimal
- password
- list box
- drop-down list
- signature
- image
- button
The automatic validation is performed when user clicks the radio button list, radio button and check box fields.
This behavior differs in Acrobat 7.x, where clicking any form field triggered an automatic validation.
