Hello,

Are you talking about the Edit Validate rule? If not can you share some screen shot of your rule where you are trying to perform this validation. If you are trying it in Edit Validate rule then its just a piece of Java code that you can write to perform your validation.

Thanks,

Hi Susan, 

Thanks for the thread but unfortunately I did read that before writing this post. I believe that post is just pointing out an enhancement request to add expression evaluates to false as a standard. 

It would be nice to know how to do the expression evaluates to true from a different method so the opposite can be done. 

I have an expression below that evaluates to true.

@IsInPageList("Specific Value","Property in List",PageList) 

I would like to have a condition where I can use the expression above evaluates to false. 

Thanks,
Masato
