[gatein-issues] [JBoss JIRA] Commented: (GTNPORTAL-1169) Likely issue on DataStorage 's cache , listeners
[
https://jira.jboss.org/jira/browse/GTNPORTAL-1169?page=com.atlassian.jira...
]
Minh Hoang TO commented on GTNPORTAL-1169:
------------------------------------------
As the test cases in component.portal always pass. It 's likely that below states
occur in the DataStorage blackbox
1. When dataStorage.create(pageNavi) is invoked. The parsed argument pageNavi is put on
the cache, meanwhile a real creating query is dispatched to JCR
---> that explain why the first getPageNavigaiton() is non NULL, and why the test cases
pass
2. Once the creating query is dispatched, the cache is cleared
----> that explain why during the loop the getPageNavigaiton(..) often returns NULL,
or the NPE exception reported by Social team
3. The creating query is handled succesfully in data layer, then events would be fired and
relevant listeners syncrhonize the DataStorage 's cache with model in data layer
Likely issue on DataStorage 's cache , listeners

Key: GTNPORTAL-1169
URL: https://jira.jboss.org/jira/browse/GTNPORTAL-1169
Project: GateIn Portal
Issue Type: Bug
Affects Versions: 3.0.0-GA
Reporter: Minh Hoang TO
Assignee: Julien Viet
Social team reported that there is delay in creating PageNavigation. Below code snippet
illustrates the scenario
String owerType = "group";
String ownerId = "blahblah";
PageNavigation pageNav = new PageNavigation(ownerType, ownerId);
dataStorage.create(pageNavi);
pageNav = dataStorage.getPageNavigation(ownerType, ownerId); ---> Here the pageNav is
not NULL
for( int i =0; i < 100; i++)
{
pageNav = dataStorage.getPageNavigation(ownerType, ownerId);
if(pageNav != null)
{
break;
}
else{
//Print out something saying that pageNav is null
}
}
pageNav = dataStorage.getPageNavigation(ownerType, ownerId); ---> Here the
pageNavigation is always non NULL, as about 45 seconds has elapsed
Within the loop, the pageNav is often null.
From UI, if user create a new navigation and click immediately on that navigation (Ex:
Create a Space in Social), then there is NPE
