We have a report definition that uses a parameter in its only filter. We have checked the box " use null if empty".

When we run the report without providing a parameter, it returns zero results. Which is expected, the filter blocks all records as the parameter is not filled in.

Now we have a datapage with the same (not mandatory) parameter, which is loaded by the report given above. We use "pass current parameter page". If we run the datapage without providing a parameter, the datapage is loaded with all records in the table. In other words: the filter is not working. This is an unexpected result.

We can think of a workaround, but we were wondering if somebody has experienced this before, and if this is a bug in Pega?

(Changing the "pass current parameter page" to passing the actual parameter does not change the situation sketched above)
