HtmlToolBar can not be saved in session: Non-serializable at

mores Jan 8, 2008 11:00 AM

I am currently building a org.richfaces.component.html.HtmlToolBar on a query from a database. The only way it will work is with a managed-bean-scope of request. When I try to use session scope I get:

java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute

How can I improve performance by caching the build of this tool bar ?

What's your application server?

I am currently running this under tomcat 5.5 with facelets so I can use JSF RI 1.2

I guess the problem is not in the component itself, but in the value of some attribute, that is not Serializable. Could you please provide page & beans code?

I have tried to make the code as small as possible and still exposes the stack trace

Nick, can you reproduce this or do I need to supply more details ?

The org.richfaces.component.html.HtmlToolBar cannot be saved in the session, but it CAN be saved in a cache.

By using OSCache my menu build time has decreased from 2 seconds to 2 miliseconds !

I think this error is because < distributable /> is in the web.xml.

I am now seeing similar errors using fileUpload when distributable is turned on.
