value of context variable is not an instance of the component bound to the context variable

Sometimes this is caused by a hot deploy problem and can be rectified by doing a clean redeploy/restart. Other times it may indicate that you have a Seam component name (@Name annotation) the same as a variable name. Check your code carefully to see if your context variable is not already in use as a Seam component name. If it is, change one of them.
Check Factory and Seam Component
