EStudio End User Form - Text Field - Validation Regex

David Smith

This should be simple, but there are absolutely no technical documents for EStudio, so nothing is simple with EStudio development. I have opened a support ticket, but even the support folks don't seem to know much about EStudio under the hood. What I am trying to do is solve this simple requirement: The input text field should not allow an entry less than 4 characters in length.

My validation regex looks like this: [0-9a-zA-Z]){4,}

I've tried some other variations, such as this and similar: ^([0-9a-zA-Z]){4,}$

No luck. It just happily allows an entry of: 123 or 1 or nothing entered at all. And if I modify the regex to be "[0-9a-zA-Z]){4,6}" and enter something much longer than 6 chars, it still allows it. So clearly this syntax is not registering with this field. I am wondering if anyone has had any luck with validation regex in EStudio with a similar requirement with success and what syntax was used. Or some other regex for something else with an obviously different syntax may be helpful as well. With no tech docs as a guide, and no experts at OpenText seemingly available, I am really at a loss here.
