Summary

A grid layout displays a user worklist. The source of the grid layout is a Data page which gets populated from a Report Definition.
The report definition has a join and hence the resultant structure is a pagelist having embedded pages of the joined class.

On trying to use the properties of the embedded page within the grid layout, the application does not allow this.

Error Messages

String value of a cell:
.pxPages(<your data page>).<property name> doesn't exist or is not a valid entry for this ruleset and its prerequisites

Steps to Reproduce

1. Create a Report Definition in Index-WorkPartyUri class and Join it with the Work class.
2. Create a Data Page and use the Report Definition and Data source.
3. Create a section, drag a repeating grid and refer the above created Data Page as the Data source.
4. Try to use any embedded property of the work object in the column of the grid layout and save the rule.

Root Cause

This is an issue due to Pegasystems' code or rules.

Resolution

Local-change is to modify Pages and Classes TAB to specify:

<your Data Page name>.pxResults - class it is applied to .pxPages(<your synonym for join>)
<your Data Page name>.pxResults.pxPages() - the same as above

This allows the property to be set as: .pxPages(W).<property name>

The same value can be set as Parameter for action if needed, after performing the mentioned modifications.
