Exception on sorting optimized table.
We have a table that has "Optimize code" option checked.
This table when sorted on any column except first, and when filter is applied , and user clicks to sort again, exception is thrown which is pasted below.
This exception is coming form step 17 of @baseclass.pzDoListAction from pega-UiEngine:08-08-05.
Param value pySectionName is coming blank in step 17 which needs to be set in step1 by pega.getUIEngine().getGridUtilities().setPartialParams(tools);

@VarunP16768037 The exception you're facing occurs due to a missing parameter (pySectionName) when sorting an optimized table after applying a filter. In Pega, optimized tables rely on dynamic UI stream generation, and this parameter (pySectionName) is critical for identifying which section to render during the partial refresh. When filters are applied and then sorting is triggered again, the section name is not being passed properly — likely because the partial parameters are not set in the correct order or are getting cleared. To resolve this, ensure that your section is correctly configured and that the pzDoListAction activity is called with all required parameters. One workaround is to override the section rule and explicitly include pyStreamName and pySectionName parameters using a pre-processing data transform or in the action parameters of the grid. Also, check if the latest version of the section or UIEngine rules are being used, as this could be a version-specific bug.
