[jira] Commented: (TRINIDAD-1632) Trinidad 2 - exception thrown
when partial state saving turned on
[ https://issues.apache.org/jira/browse/TRINIDAD-1632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12776199#action_12776199 ]
Gabrielle Crawford commented on TRINIDAD-1632:
----------------------------------------------
What's happening
First render:
- UIViewRoot.setRenderKitId - id is stored in the properties
- markInitialState called for UIViewRoot, so the id won't be state saved
postback:
- neither UIViewRoot.setRenderKitId or markInitialState called, so there's no renderKitId on the viewRoot
- UIViewRoot.getRenderKitId called, it tries to look up the renderKitId in the properties map, but it's not there, so returns null
