Have anyone used IsPageListEmpty() function ?
I need to create a when condition which would check if a pagelist is empty or not. i can see there is a function named IsPageListEmpty which has three arguments.
does anyone know what values should we have to pass to these arguments.
@Utilities.IsPageListEmpty(tools,aPageListRef,aPropName)
tools - ?
aPageListRef - ?
aPropName - ?

i used @(Pega-RULES:Utilities).LengthOfPageList(pagelistpropertyname) in a when rule and mentioned it in an activity. it throwed the below error when it tried to evaluate the when rule.
The Flow Action pre-processing activity "activity name" failed: cannot be null or blank. page: "page list name".
Details: Invalid value for aReference passed to com.pega.pegarules.data.internal.clipboard.ClipboardPageImpl.getProperty(String, char).

I used this to check if PageList is empty.
@(Pega-RULES:Utilities).LengthOfPageList(.PageListName) == 0
Hope it helps.

It sounds like it would be useful to track down why you are getting the error you reported. If you paste some snapshots showing both your design and the tracer clipboard values, we can take a look. /Eric

Hi Dilipan,
I would take a look at the OOTB activity pzGetApplicationCompletionPercentage, which does use the utility function in the when rule pyDoBusinessObjectivesExist in step 5.
