Hi,

Sometimes, i've got the following error in my logs

2008-07-31 17:29:46,100 ERROR [org.jboss.seam.web.ExceptionFilter] exception root cause
java.lang.IllegalArgumentException: value of context variable is not an instance of the component bound to the context variable: org.jboss.seam.captcha.captcha

I can't determine why it's append ...

I override the seam captcha component as follow

@Name("org.jboss.seam.captcha.captcha")
@Scope(ScopeType.SESSION)
@Install(precedence = Install.APPLICATION)
public class MyCaptcha extends Captcha {

I run on jboss 4.2.2GA jdk 6 and seam 2.0.2.SP1

Any idea ? thanks !
