We have a pagelist property which is populated based on the values selected on a screen as a checkbox and submitted. Once the flow action is submitted, we see that at times the flow action executes successfully while at other times we get the error "The property was of mode Page List while com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.getPageValue() was expecting Page mode ". The property for which the error is being thrown has been created in the system as a PageList property. Select one of the checkbox values and submit the screen. The error is seen on the screen intermittently. Traced the error and we could see that this was happening in step 5 of the activity “ReCalculateAndSave” in Work- class. Any resolution for this?
