--------------------------------------------------------------------
not sure you understood correctly the issue.
there is an ajax request to the server, the server detects that there is a
problem with the response, in this case that the reponse would generate an
invalid html page with duplicated IDs and sends an error message back.
until now everything is fine. the point is that the client can not correctly
handle the error message because the ajax response with the error message is
not well formed:
<?xml version="1.0" encoding="utf-8"?>
<partial-response>
<error>
<error-name>java.lang.IllegalStateException</error-name>
<error-message><![CDATA[component with duplicate id "form:myId"
found]]></error-message>
</error>
</changes> <======= HERE
</partial-response>
