Sorting Issue in Repeating Grids
I am using a repeating grid, where sorting should be enabled. Grid Source using is ABC.pxResults.
Able to sort only some columns. For some columns I am getting error like below.
Exception Trace com.pega.pegarules.pub.clipboard.InvalidParameterException: Failed to process comparator list, com.pega.pegarules.pub.clipboard.InvalidParameterException: Cannot get property information for: Class:"ABC-Data-XYZ" Property:".abc". Details: Invalid value for aClassName, aPropertyName passed to com.pega.pegarules.data.internal.clipboard.PageComparator.getDefaultComparator(Executable, String, String). Details: Invalid value for aComparator passed to com.pega.pegarules.data.internal.clipboard.Sorter.sortPageList(ClipboardProperty, String[], boolean[], String[])

Wrf to this article:
Eventhough I am using toplevel page of clipboard (ie. ABC.pxResults ) as my grid source, I am able to sort for some columns and for some columns I am not able to.
If it is the Pega Code issue, it should not work for all the columns I assume. Please confirm and suggest a solution.

Hello Jeevan,
For columns where sorting is not working, are you using any section include or non-auto generated controls?
No I am not using section include or non- auto generated controls.
Repeating grid directly. For some columns - sorting worked and for some, it did not.
Hi,
What is the data type of all these properties, Is the non-working column is having some different type.?
Accepted Solution
Hi Neha,
All are of same data type.
But while checking for this, I came to know that - the .pxObjClass of the property in the clipboard page (ABC.pxResults ) is not same as the class of the source ABC.pxResults (which I gave in pages & classes of this section).
So I explicitly used Page-Change-Class in the activity (where this page is populated). Then it worked fine.
Thanks,
Sri Lalitha.
Hi Jeevan,
I think you got confused with the referred PDN article, it says to use the Page List property which is embedded within the pyWorkPage(i.e. Orders page list property which is embedded in the pyWorkPage) instead of using the Top level clipboard page(i.e. FinalResults.pxResults).
So perform this change and let us know if it helps you.
