Seam and tomahawk-sandbox graphicimagedynamic

[frehan]

Hi!

I am trying to use the graphicimagedynamic component of sandbox togheter with Seam. the graphicimagedynamic uses a ImageRenderer where the FacesContext is set using:

public void setContext(FacesContext facesContext, ResourceContext imageContext) throws IOException

The problem is that when facesContext.getApplication() is called it is null.
IF I then try with the Seam context Contexts.getApplicationContext() or Contexts.getSessionContext() it is also null in the renderer.

Has anybody a solution for this problem. Or any other working method of diplaying a dynamic image in a web page using seam and jsf.?

And, as pointed out, A4J has a component as well. I would steer clear of tomahawk where possible and especially sandbox.

Thanks for your reply!
I have tried the A4J component, but I always get an Application context not available when using it with seam.

I have also tried your component, but I am not using faclets so I did a taglib to work with jsp/jsf (seam) but I get exceptions about missing metohds, and more.. I will try to post the stacktrace..

I believe you would need to write a Tag file for it as well but I've never developed tags for JSP.
