cannot achieved ajax capability with a4j:commandButton

[orkun]

hello

I couldnot achieved partial update using -a4j:commandButton- & -a4j:mediaOutput-

As far as I have understood from partial update and a4j, when I operate --a4j:commandButton id="graticule" --,

my --a4j:mediaOutput id="harita1"-- is expected to be updated. But it never updates.

Instead it requires whole page update with --oncomplete="document.forms['harita'].submit();return false"-- in

--a4j:commandButton id="graticule"--

But I need partial update of my a4j:mediaOutput id="harita1" when I use reRender="harita1" in a4j:commandButton

Could you tell me where I am wrong ?

here is my code fragment

~~~~~~~~~~~

<a4j:commandButton id="graticule" value="graticule"
                            action="#{haritaBean1.graticule}"  reRender="harita1"
                            image="./images/Graticule2.png" >
                           
</a4j:commandButton>

~~~~~~~~~~~~

<a4j:mediaOutput id="harita1" element="img" mimeType="image/png"
                            createContent="#{haritaBean1.drawMap}"
                            style="width: 500px ; height:500px " >

</a4j:mediaOutput>

Hi,

Try setting cacheable="false" for a4j:mediaOutput. If this doesn't help, add a4j:log to the page and check if there are any errors/warnings there.

Use workaround used there http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf?c=fileUpload&tab=usage (define f:param nested to mediaOutput or just component value defined with the property which returns different values for every request) In other case - browser gets image from cache as URL for img not changed.

B.t.w. https://jira.jboss.org/jira/browse/RF-7055 - should handle that in future automatically.
