The actual Clipboard Impl class is throwing an exception - could be a lot of reasons why that might happen. Have you traced where the exception is occurring? (and searched the Forums to see if someone else has encountered a similar problem) Posted: 5 years agoAmitK248 CapGemini replied to AMIT158KThanks. Yes. I traced the issue , When flow reached the External assignment , Work - External activity is executed.However step 1 and 2 are skipped and activity exits after completing step3. ..followed by: " Cache Hit (not found) 0.0000 Looking for instance Rule-Message WRONG CLASS FOR PARAMETERPAGE: COM.PEGA.PEGARULES.DATA.INTERNAL.CLIPBOARD.CLIPBOARDPAGEIMPL in the Rule Resolution cache Cache Hit (not found) 0.0000 Looking for instance Rule-Message WRONG CLASS FOR PARAMETERPAGE: COM.PEGA.PEGARULES.DATA.INTERNAL.CLIPBOARD.CLIPBOARDPAGEIMPL in the Rule Resolution cache " Step 3 being implemented suggests @PageExists(".pyWorkParty(" + param.Party + ")", tools) is coming false...any suggestion.
