Portals are not rendering the section properly
User made changes for few rules in ruleset version in their application environment.
However, due to these changes they observed that all portals got blanked out for a particular section which are related to the application change.
Steps to Reproduce
1. Copy the rule from higher ruleset version to lower version.
2. Observe whether the rule is executed during run time.
An issue in the custom application code or rules.
User has a list view control in the section configured in higher ruleset.
Later, user has copied the section and pasted it the lower ruleset version, and somehow the generated java for the rule was not generated properly.
That is, the list view was not copied properly.
Perform the following local-change:
Re-configure the section in the lower ruleset, by adding the list view explicitly in the section and save the rule.
By this, the stream rule was properly re-generated and the portal was able to render the section/list view during run time.
