refresh a4j:mediaOutput

[pschuett]

Hallo,

I want to refresh an a4j:mediaOutput by a button click.

<a4j:mediaOutput id="myImage" element="img" cacheable="false" createContent="#{myBean.paintImage}" />

...

<a4j:commandButton immediate="true" render="myImage"/>

If I press the button the image is not refreshed.

If I set execute="@form" for this button it works, but I do not want to refresh the whole form.

I also try a4j:region around both but it does not work.

Perhaps someone has an idea for me.

Thanks for any hint.

Ciao

Hi Peter,

i built your code by your example and it works for me. I suppose, that something on your page interferes with the rerender. I used following code:

  <h:body>
     <h:form>
        <a4j:mediaOutput id="myImage" element="img" cacheable="false" createContent="#{pictureModel.getImage}" />
        <a4j:commandButton immediate="true" render="myImage" />
     </h:form>
  </h:body>

Best regards,

Mark
