Workbench and Sessions [message #1386549]

Hello,

I currently work on a big RAP application which has been migrated from a RCP application.

My current goal is to provide a multi-user access to this application.

My problem is :

When i launch the application and access to it with the browser for the first time : no problem.
When i try to access again to this application (with a second tab or in an other browser) i access to the initial application session and i needed to refresh the page to access to a other session.

So my question is : How to have a session for each workbench/page/tab/user ?

I tried to use the session singleton but i don't know how apply it on workbench in my application.

I would be very grateful for any help you could might be able to give me on my problem.

Thank you.

Clément

Hi,
you have a separate Workbench instances for every UI session (see
Workbench#getInstance()). If you have static instances in your code, you
should replace them with UI session singletons (see
SingletonUtil#getSessionInstance or SingletonUtil#getUniqueInstance).
HTH,
Ivan

Hi Ivan,

First, thanks for you reply.

Do you know why i need to refresh the page to get a new workbench instance ?
This is my current problem, i just need a new instance for each new access...

Hi,
probably something in your code. Check all your static instances as a
start. Our Workbench Demo [1] is working fine in multiple tabs.
BTW... which RAP version are you using?

Hi,
My RAP version is 2.2
I will try to check my static instances but it is a very huge application with hundred of static attributes so it will take a long time...
The workbench demo doesn't work since i deleted rap.eclipsesource cookies on my browser
And before deleting cookies i had always the same instance (even if i tried a other browser)

Thanks for helping,
Clément

Hi,
this is strange. If you can create a reproducible scenario with our
Workbench Demo that demonstrate the "same instance" problem, please open
a bugzilla.
Thanks,
Ivan
