Summary

A page from a data page was passed as a "page name" parameter to an activity. A property value was set on that page using Property-Set. Null pointer exception was observed when the activity was executed.

Error Messages

Not Applicable

Steps to Reproduce

1. Create a Node-Level data page.
2. Create an activity which accepts a Page Name parameter.
3. Set Page Name parameter to data page name.
4. Execute Property-Set referencing page name parameter.

Root Cause

The parameterized syntax of data page name D_DataType[p1=v1] is supported only in few controls like data transform's action source and target, and so on. The syntax is supported wherever expression builder is supported. So, parameter prompt text input in activity run rule dialog does not support it.

Resolution

Set the required parameter(s) of the data page before referring to the data page.
