iabughosh Feb 15, 2012 5:36 AM (in response to joesepp1974)hello joesepp,
i think your value attribute must be something like this :
value="{mbj3.WochenChar}" not value="WochenChart"
and try also adding session="true" attribute to your a4j:mediaOutput.
regards.

joesepp1974 Feb 15, 2012 5:56 AM (in response to iabughosh)Hi Ibrahim!
The "value" attribute is not the problem. this attribute takes an object, so my string with the name of the chart to create is working fine.
I tried the "session" attribute, but "session" is not definded in the component´s interface and it did not work.
The chart is shown correct loading the page for the first time, but when I want to reload the chart with ajax, the a4j:mediaOutput is not calling the "createContent" method in my bean, and it still shows the old chart.
When I make a complete page refresh without ajax, the updated chart is shown correct. So it is only the question how I can force the a4j:mediaOuput to call the "createContent" method and show the actualized chart.
greetings

</h:body>
</html>when i click the button, the actionListener creates a new chart and renders the baseValueForChart with the new value, but the a4j:mediaOutput don´t calls the "createContent".

iabughosh Feb 15, 2012 8:14 AM (in response to joesepp1974)i think your problem is in render attribute:
<a4j:commandButton value="update" render="chart,baseValueForChart" actionListener="#{testBean.test2()}"/>
you can separate by two elements using space , try render="chart baseValueForChart" or render="@form"
regards.
