RF4 a4j:mediaOutput x CDI ConversationScoped

edilmar Jul 1, 2011 1:53 PM

Hi,

Environment: NetBeans7.0 + GlassFish 3.1 + CDI 1.1 + JSF2.1 + RichFaces4.0.0-Final.

I tried to use a4j:mediaOutput to show a graphic generated by JFreeChart, like this:

<a4j:mediaOutput element="img" cacheable="false" session="false" id="graficoTotais"
            createContent="#{bean.criarGraficoTotais}"
            mimeType="image/jpeg" alt="img" standby="Carregando gráfico..."
            />

I tried with session=false and session=true.

The code for the bean is here:

public void criarGraficoTotais(OutputStream out, Object data) throws Exception {
    JFreeChart chart = criarGrafico(criarDataSet());
    BufferedImage buffImg = chart.createBufferedImage(500, 375, BufferedImage.TYPE_INT_RGB, null);
    ImageIO.write(buffImg, "jpeg", out);
}

If I configure the bean like ConversationScoped, GF arises this error:

GRAVE: org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.ConversationScoped

If I use SessionScoped, all works fine. Then, the problem here I think is that the "ImageIO.write(buffImg, "jpeg", out);" writes the image after the page was processed, there is no context conversation available at this moment.

Is there some work around to allow a4j:mediaOutput + bean ConversationScoped?

I'm struggling against the same issue.

I'm using JBoss AS 7.0.1.Final + RichFaces 4.1.0-SNAPSHOT

I basically copied the rich:fileUpload example from the showcase (which contains also a4j:mediaOutput).

If I change the scope of the bean to @ConversationScoped, I get the same exception you get:

I initially thought that the conversation got ended for some reason, but after adding the following:
<h:outputText value="#{javax.enterprise.context.conversation}"/><br/>

I noticed that the conversation works fine.

The problem must reside in the I/O objects such as OutputStream.

Hi,

I did what you said like below, but the same error occurs. My app server is with GlassFish 3.1.

<p>
<h:outputText value="#{javax.enterprise.context.conversation}"/><br/>
<a4j:mediaOutput element="img" cacheable="false" session="false" id="graficoTotais"
            createContent="#{controller.criarGraficoTotais}"
            mimeType="image/jpeg" alt="img" standby="Carregando gráfico..."
            />
</p>

Sorry for being unclear.

By "the conversation works fine" I only meant that the conversation was still alive and long running.

As for now, it seems the only way to get rich:mediaOutput to work is to set the bean scope to @SessionScoped

You are right. With @SessionScoped it really works.
What I did was to save the image in a temporary web dir, and use h:graphicImage instead of mediaOutput.

I registered this issue in JIRA: https://issues.jboss.org/browse/RF-11585
