Virtual Page Lists do not support this method (Data Transform)

Hi,

I'm trying to look into the current application Work classes to check if a class already exists before assigning it to a case, like using Dynamic Class Referencing (DCR). I found ootb Data page D_AllClassesInApp contains this information, but when trying the below When rule it results in an error:

When rule condition

Also using an expression like this results in the same error:

@IsInPageList(Param.CountryClass, .pyClassName, D_AllClassesInApp.pxResults)

Error: "Virtual Page Lists do not support this method"

Since I'm not trying to edit the items of the Page list, I don't understand why this approach is not supported...

Also any thoughts on work-around approaches are welcome.

Thanks

-Jose
