Scenario:

• WebEdit functionality is widely used by FirstSpirit editors
• they often try to work in different projects at the same time
• in general they use up-to-date browser versions offering multi-tabbing in one browser instance

Environment:

• FS 3.1, FS 4.0, FS 4.1, FS 4.2 R2, FS 4.2 R4, FS 5.0
• FirstSpirit WebEdit
• Multi-tab enabled browsers like FireFox, >IE6, Opera, etc.

Problem description:

• multi-tab browsers share sessions (JSESSIONID cookie) between different tabs
• opening multiple FirstSpirit projects in different browser tabs and working on them in turn
  lead to error messages and data lost in all tabs simultaneously
• "not connected" error messages appear in the Servlet Container logs (Tomcat or Jetty)
  endlessly (see below)

ERROR 17.02.2011 18:05:22 (de.espirit.firstspirit.client.webedit.servlets.SaveDataAction): SaveData.doAction() failed - java.lang.IllegalStateException: not c

• the following error message appears within WebEdit (see screenshot below):

Solution

• offer a tab-unique and tab-safe session handling in FirstSpirit WebEdit
• refer to the Java Seam-Framework solution. Details can be found here:
