In customer application 'WorkFormStandard' HTML Fragment was overridden, hence JQuery related JS and CSS were not getting loaded. By overridding OOTB 'WorkFormStandard' HTML Fragment rules this issue is resloved.
"WorkFormStandard" rule is locked and we don't have any open accessgroups/rulesets to make a saveas and edit the rule. Private edit doesn't reflect the changes.Can you suggest us for some other approach.
If so then you can try one thing. in your Pega 6 environment change that rule in one of the open or existing application rule set then take only R-A-P of that rule and import into Pega 7 using email@example.com
