Dynamic graphicImage doesn't work w/ConversationScoped bean
Posted: 09 Nov 2011, 19:32
I was trying to use a graphicImage tag with a value supplied by a ConversationScoped backing bean that pulls an image out of a database BLOB column. However, it wasn't working. All I ever got was the alternate text. After chasing the problem from the server side for 2 days - where I concluded that everything was working fine - I finally decided to look at the generated page to see if it might hold any clues. In there I found the <img> tag for my image:
In Firefox's Source display window it created a link for the img's src attribute, so I clicked on it and got another page of source that included the following error:
I get the same error whether or not I actually begin a conversation (e.g. in a preRenderView event). I don't know if there's some kind of incompatibility between PrimeFaces' graphicImage and Glassfish (3.1.1), between PF and Conversation scopes, or something else. I'd like to submit an error report to someone, but I'm not even sure who the org.jboss classes belong to.
I was able to work around the problem by using a SessionScoped rather than ConversationScoped bean.
