Hi Neal,
I will try to explain what I have done so far.
-Actions performed by Admin user
1. Created a project site from School site setup .
2. Then create a user under user section.
3. Assigned user to this created project site with role admin(so this user will acts as a site admin).
-Actions performed by site admin user :
1. Login with to sakai , able to see added project site assigned to him ,including My Workspace . Able to access all site tools .
2. Created users as student(including parent), teacher.
-Login as site admin or teacher or admin :
ü Able to see 2 tabs at homepage as My workspace & assigned site .
ü Able to see tools on My Workspace home page like calendar,Message,Recent announcement .
ü Able to see similar tools in site home page also.
Login as Student:
ü Able to see 2 tabs at homepage as My workspace & assigned site .
ü Able to see tools on My Workspace home page like calendar,Message,Recent announcement .
ü Able to see similar tools in site home page also. Only no session established no tool session established error displays under Recent announcement iframe.
ü Able to see recent announcement successfully in My Workspace home page.
This error comes for every site assigned for any student user only.
I am wondering as I debugged, got to know that all tools displaying on home page like site information display, calnder,chat messages, Recent announcement comes from the same code .
Please let me know if you need anything more explanation.
Thanks ,

I'm not aware of a problem like this in 2.9.x . It would have been a blocker bug, I assume.
>I have created a site , created site-Admin, then by using siteadmin, created users like teacher,student etc.
It sounds like this is an issue in the synoptic view in the Home page of a particular site? What do you mean that you created a "site-Admin"? Was this a course site or a project site you created? How did you create it?
It sounds like :
Announcements in a site work fine
Announcements synoptic view on My Workspace works fine
Announcements synoptic view within a course or project site does not work for the student/access role?
Please provide a step-by-step way to reproduce the issue and I'll try it on Sakai 2.9.x .
Thanks,
Neal

Hi All,
Is this issue is invalid? I have seen similar error posts on sakai forum also.
Please at least can anybody provide me guidance to resolve this problem. I am trying to find out root cause behind this error , but still no luck. It ‘s not even calling any announcement related methods. Then how it is generating (rendering )announcement sections for other users ?
I am currently debugging sakai-portal-render-impl, sakai-portal-render-engine-impl. And when this error comes , its not showing even showing any errors in logs.
Anybody can tell me atleast what can be the possible reason behind this error ?
It’s been a week I am expecting a positive response.
Thanks

Hi Sakai ,
Can anyone help me to solve this issue ?
Is this error belongs to only 2.9.1 src ?
I have tried to used 2.9.x all version for source code portal-render. But still that error comes . Is somebody is getting same error for student in announcement ?
Thanks,

Hi ,
I have tried with debugging functionality for site page rendering ,I am able to see session in debugger mode also .
Session s = SessionManager.getCurrentSession();
Value for session is available .
So how error can come with saying no session established .
And if tool session is not established then how can user will be able to see other tools like gradebook,attendance,profile,subjects.....
As my student user is able to see all these tools, so tool session is established .
But one more thing I have noticed is : in includePageBody.vm file value for : ${tool.toolRenderResult.getContent()} is nothing but whole error “session established no tool session established error .
<!-- end Tool Col2 -->
<!-- start Tool Body -->
#if (${tool.hasRenderResult})
<div class="portletMainWrap">
${tool.toolRenderResult.getContent()}
</div>
#else
<div class="portletMainWrap">
<iframe name="${tool.toolPlacementIDJS}" id="${tool.toolPlacementIDJS}" title="${tool.toolTitle}"
class ="portletMainIframe"
height="475"
width="100%"
frameborder="0"
marginwidth="0"
marginheight="0"
scrolling="auto"
src="${tool.toolUrl}?panel=Main">
</iframe>
</div>
#end
<!-- end Tool Body -->
Above code generates contents for announcement for users.
Please guide me to solve this error , I am really stucked with this.
Thanks,

Hi Sakai Team,
I am using sakai source code 2.9.1 .
I am getting an error for user Student when he tries to see his site homepage –error comes for announcement frame only as “no session established no tool session established error”.
I will try to explain what I have done till so far.
I have created a site , created site-Admin, then by using siteadmin, created users like teacher,student etc.
So after that when I tried to login with different users, it only gives error 'no session established no tool session established' for student user only in announcement section.
It displays correct announcement when student user comes in My workspace. So it means this error comes only when it comes to site.
I tried to debug source code provided at <https://source.sakaiproject.org/svn/sakai/tags/> https://source.sakaiproject.org/svn/sakai/tags/ for announcement , I have tried to add logs to all methods in class "AnnouncementAction " as this is the file where all announcement related actions goes on like create/edit/update ,display announcement.
I am able to get all added logs for other users, but unable to get not even single log for student user "when student user tries to see announcement in site."
After some more research I found that this site or by default home page for user gets rendered from portal-render(part of portal), where I got to know this error gets loaded from error.vm page.
Why this session error comes for only user student and in site only ?As announcement gets rendered successfully in by default Myworkspace tab.
Can anybody guide me how I can resolve this error so that student will be able to see his site’s announcement similar to other users(admin,teacher etc).
I also tried to truncate date for the tables related to announcement which I knew so far i.e announcement_channel & announcement_message
I have also seen similar posts are available on sakai forums , but nobody has given solution for it.
Please guide me in this context.
Thanks,
