khaliq/Nusa, I am also getting the cast exception. I was able to create a regular JSF managed bean and bind/cast to it just fine however, binding to a Seam component caused the cast exception: Caused by: java.lang.ClassCastException: org.apache.myfaces.trinidad.component.core.data.CoreTable cannot be cast to org.apache.myfaces.trinidad.component.core.data.CoreTable I can only speculate at this point, but I assume it's something to do with AOP mechanisms changing something about the class during the binding process. Generally in Seam one would be injecting classes based on interfaces or entity beans rather than 'raw' object instance. I would appreciate it if someone could explain what's going on here or direct me to some further reading.
The reason I was binding the table to the Seam component was to get a handle on the component before render response so that I could initialise row selection for the <tr:table ... rowSelection="single"> mode. This requires direct access to the component instance after it has been bound to its data. From what I can tell, my efforts were in vein due to the life cycle of Facelets: * BEFORE_RENDER_RESPONSE event fired; * facelets build process starts, binding to my seam component occurs; * getter is called for the component; * data model factory is called; * AFTER_RENDER_RESPONSE event fired; Basically, the last possible hook into this process (that I could find) was with the getter for the component or even the data model factory (yuk!). Since the actual data model binding occurs after this, there is nothing that I can use to set the selected row keys. As a general comment, I have been able to do this sort of processing easily under the Java Studio Creator 2 application model using the prerender() method on my backing beans. This is essentially a hook invoked during the BEFORE_RENDER_RESPONSE phase. With this in mind, I tried experimenting with Seam "org.jboss.seam.beforePhase" event but this is fired before facelets even starts building its tree. I understand that the JSC2 approach and the facelets approach are very different, but it does seem odd that there is no way to get at the underlying JSF components before they are rendered. I assume that facelets tree is built during this phase? Or perhaps (probably) I'm missing something, but I have searched for the best part of a day on this and not come across anything. C.
