Rerender is stronger than the pages.xml

                 Key: JBSEAM-3863
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3863
             Project: Seam
          Issue Type: Bug
    Affects Versions: 2.1.0.GA
            Reporter: joe Koch
            Priority: Trivial


hi,

we had a bit a strange thing on one of our pages after we added a a4j thing. 

as it used to work correctly:
we entered a value in a field, the browser gave us some values we entered before (auto completion). when we left the focus on the input field, the "drop down list" was still there, and we pressed a button that did a action and left the page via an return code via pages.xml

as we liked the input field to be formatted nicely we added a 

 <a4j:support event="onchange" reRender="selectUnderlyingForm"/>

so now the imput field was renderd as wished when we left the field. 

But when we left the page (with the action button) and had the values on the auto completion on the input field, the action from the button was called and exited correctly but the page reload it self an did not redirect as told on the pages.xml => we never left the original page.

we searched for days, till we found out that the render of the "onchange" was stronger than the pages.xml, without the a4j everything is working correctly. 

we did some test with the "live http headers" and saw that first the rerender goes to the server and than the button click. what is correct.

as i had not enough knowledge i was not able to see the responds for that page. may that came synchronous back after the button action? 

i guess seam should stop comunication with the page as soon as it comes to the pages.xml. i guess this is the problem.

this is not an important issue but someting hard to find!

if you need any more information i am glad to help you.

best regards
