I cannot be of big help here, since I have not Seam running currently
but as it seems, the ajax component triggers a bug in the variable
resolver of Seam, due to the fact that it causes a call back into the
application over ajax and then cannot find the method binding.
Since this mechanism works on plain jsf without any hickkup,
it probably has to be fixed on the Seam side of things, unfortunately.
Anyone from JBoss reading this?
