Require help on JBPM 6.0 - KIE workbench form modeller

[vidya_k]

Hi,

I am new to KIE workbench on JBPM and I need to know the following with respect to Task forms on JBPM 6.0 - KIE workbench:

1. Adding custom validations for different fields on the form (have discovered that there is a general message appearing when the mandatory fields are not entered).
2. Dynamic and conditional Drop downs (say, a drop down must appear based on the chosen value on the current drop down) (have discovered that 'Range' field helps for a straight forward pre-defined drop down list).
3. How to write a 'Formula:' on a field's properties window?
4. How to configure 'Default value formula:' on a field's properties window?
5. Is it possible to have multiple tabs on one UI via this KIE workbench? If yes, how can that be achieved?

Thanks in advance.

Regards,
