Are you submitting values for those components? If so, the submitted
value will be rendered, not the value from the back-end.
Try this:
<a4j:region>
<h:inputText id="propertyTag" value="#{deviceBean.tagNumber}" >
<a4j:support action="#{dostuff}" event="onblur"
reRender="mypanel" ajaxSingle="true" />
</h:inputText>
</a4j:region>
<a4j:outputPanel id="mypanel">
...
</a4j:outputPanel>
What this will do is only decode/validate/update the inputText
component. Then, the other components in the reRender will not have a
submittedValue or a local value and thus will render the value from
the backing bean instead of the value from the client.
There was another thread recently talking about similar issues an how
to clear submitted values and local values. I don't have the URL for
that one though.
Hope I understood you correctly,

Andrew,
Thanks for quick response. I will definately use the PhaseListener to debug
the problem as you mentioned . Meanwhile i was thinking maybe i
misrepresented the problem .
Here is the situation
I have textfield with a4j onblur event
As i tab out it reRenders other fields on the form . But while reRendering
dropdown fields, it picks one element after the other in that dropdown , i
could see this on the page dropdown showing one element after the other. And
then cursor goes in wait mode for a while. Finally i get the correct results
I understand the reason to this behaviour. As these dropdowns appear later
in the page, JSF tries render them as part of rendering the page. But i have
already rendered them using ajax onblur event. As i couldn't do much in the
JSF page , So in the backing bean i am generating the dropdown only if its
null. It still didnt help.I have posted the snippets in the post
http://www.nabble.com/Performance-issue-%3A-Setting-Dropdown-value-from-onblur-event-tf4037597.html.
As i am sure i am making some small mistake somewhere like in this post, i
would appreciate your time in taking a look at the code snippets in other
post
