Can I evaluate an expression formed as string type in when rule
Hi,
I have a Parameter of string type set in my Primary page which will contain some set of expression in string format which will be formed dynamically while the code gets executed. So for eg during execution based on some condition i'm setting the parameter to the following value:
Param.SearchCriteria = "@contains(.pyID,RS-239) && @equals(.pzInsKey,RS)"
Now I'm accessing this parameter from a when rule. Is there any such method in Pega using which I can dynamically evaluate the string expression passed to the when rule?
I tried with the following function but it's always returning true which should not be the case :
@CRPDecision.EvaluateExpression(Primary,"@contains(.pyID,239)") -- the SearchCriteria parameter will contain the string "@contains(.pyID,239)" actually.
Please help me out. It's urgent.
Thanks in advance.

Ya Im able to access the parameters from when rule. That's not the issue. The problem is that the when rule is treating the string parameter as a string value. So in when if we are putting the parameters directly under evaluate expression type it's not treating the string as a condition instead it's treating it as a string. This I need some way to make the when rule understand the parameter string should be considered as an expression interest of only string
