From: Ryan Wynn [EMAIL PROTECTED] I am getting the following exception and though I have looked at bug 37796 I still can't decide if what I am trying to do cannot be done with symbol replacement or if I have made a mistake. The Component jsfid attribute is null. The cause is most likely a missing clayJsfid attribute when using HTML templates and nesting a clay component. It is also likely that the problem was caused by using generic templates with symbol replacement of the [EMAIL PROTECTED]: java.lang.NullPointerException What's the rest of the NullPointerException?

In my component that extends clay, clayJsfid is tied to a value binding expression [EMAIL PROTECTED] and in my .html file I specify the symbol managed-bean-name to be myBean. I don't think that I've ever tried that. I think the error has to do with the suffix of the jsfid or clayJsfid in this case. The suffix is used to determine what handler should be used.

What are you specifically looking for? Thanks, Ryan Gary Thanks, Gary. The bindingType=Early fixed it. I guess Clay was looking for an extension and it was being done too late. My whole generic templates question came from the error msg that was reported from the clay message bundle. I thought it was telling me that particular the way I had configured my templates was too much for it to handle with symbols. But I guess I was wrong, so far Clay can handle all I can throw at it :-) One thing I did notice though was that Clay was interpreting some components nested within !-- -- in a html template. I removed the whole comment block and the error went away.
Re: [shale] clay generic templates and symbol replacement
From: Ryan Wynn [EMAIL PROTECTED] Thanks, Gary. The bindingType=Early fixed it. I guess Clay was looking for an extension and it was being done too late. I'll make that the default. I don't think that a VB bindingType even works. I'll do a little refactoring here. My whole generic templates question came from the error msg that was reported from the clay message bundle. I thought it was telling me that particular the way I had configured my templates was too much for it to handle with symbols.
