[jboss-user] [JBoss Seam] - Seam conflict with a4j:include and a4j:support
I have already shared this with the ajax4jsf forum, but they believe this is more of a
seam issue.
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4076264#...
I am using a4j:support and onblur to do field validation on an edit screen.
The edit page works fine standalone.
When the edit screen is included using a4j:include i get some weird conflicts.
1 - When no field is selected the Save button works fine.
2 - When a field is selected and the save button is pressed then 2 requests are fired. One
for onblur and one for pressing the button. Sometimes this works fine, but most times a
NPE is thrown.
Is there anyway to ensure these 2 requests don't conflict?
