Add validation rules to Form Field validation workflow task

[MikeAlhayek]

Is your feature request related to a problem? Please describe.

Currently we have a workflow task called “Validate Form field” which is responsible of validating field from a form. However, this task only check if the given field is empty!

Describe the solution you'd like

I think this task should include a way for the user to select different cases of validation. So we would add a new drop down menu names “rule” with the following options to name some

• Valid Email
• numeric value (when selected show min and max value inputs)
• Text (when selected show show length and max length inputs)
• Regular expression (when selected show input to capture regular expression)
• predefined list (show valid values to pick from)
• Date time (when selected show min and max value inputs)
• Date (when selected show min and max value inputs)
• Time (when selected show min and max value inputs)

In addition to the above, we would have a checkbox called required. We would have to check this box by default for backward comparability.
