https://community.appian.com/discussions/f/user-interface/14596/validating-the-regular-expressionHi, I have requirement where user enters a regular expression in text field and i have to validate if the regular expression entered is correct or not. Any leads will be appreciated. Thanks, Prashanten-USTelligent Community 12https://community.appian.com/thread/65447?ContentTypeID=1Thu, 28 Mar 2019 05:01:53 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:b160ab0c-6d65-4174-96b6-390691d51bfbjosep<p>Please let us know more about the requirement but what I can tell you is that there is a regex plugin. </p> <p>What I don’t get is the regular expression validation, can you define if “is correct” basically if you put a bunch of characters in a regular expression that is valid? And how complex you want the regular expression yo validate but here I found an interesting post like “regex to validate regex”. </p> <p>The post:</p> <p><a href="https://stackoverflow.com/questions/172303/is-there-a-regular-expression-to-detect-a-valid-regular-expression">stackoverflow.com/.../is-there-a-regular-expression-to-detect-a-valid-regular-expression</a></p> <p>Hope this helps </p> <p>José </p><div style="clear:both;"></div>https://community.appian.com/thread/65436?ContentTypeID=1Wed, 27 Mar 2019 15:26:14 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:5142fa26-e7a0-4800-ba5e-9d446532c3c8Robert ShankinWhat&#39;s the use case for end users to enter regex into Appian at runtime?<div style="clear:both;"></div>
