a4j:support don't invoke action within rich:fileUpload

[le_chat]

Hi all.
I have some troubles with <rich:fileUpload>.
1) if i put <a4j:support action="#{test.actionTest}"> in it, this action is not invoked.
2) some fields are changed during request, but client not refresh theirs.

this is my page:

<f:view>
 <h:form>
 <rich:panel id="uploadPanel">

 <rich:fileUpload id="upload"

 acceptedTypes="dbf"
 autoclear="false"
 disabled="false"

 required="true"
 requiredMessage="Empty input..."

 fileUploadListener="#{test.fileUploadListener}"
 immediateUpload="false"
 maxFilesQuantity="1"
 noDuplicate="true"
 rendered="#{test.state=='uploading'}"
 uploadData="#{test.uploadedFiles}"

 listWidth="700px"
 listHeight="174px">

 <a4j:support event="onuploadcomplete"
 oncomplete="alert('oncomplete action')"
 action="#{test.actionTest}"
 reRender="info"
 />
 </rich:fileUpload>

 <a4j:outputPanel id="info">
 <h:outputText value="state: #{test.state}"/>

 <rich:panel rendered="#{test.state=='completed'}">
 <h:outputText value="File has been uploaded."/>
 </rich:panel>
 </a4j:outputPanel>

 </rich:panel>
 </h:form>
 <a4j:log popup="false" level="ALL" style="width: 800px; height: 300px;"></a4j:log>
</f:view>

this is my bean:

public class TestBean {

 private static final Logger LOGGER = Logger.getLogger( TestBean.class.getName() );

 private static final String STATE_UPLOADING = "uploading";
 private static final String STATE_COMPLETED = "completed";

 private String state;
 private List<UploadItem> uploadedFiles;

 public TestBean() {
 state = STATE_UPLOADING;
 uploadedFiles = new ArrayList<UploadItem>();
 }

 public void fileUploadListener( UploadEvent event ) throws IOException {

 UploadItem item = event.getUploadItem();

 if ( item != null ) {
 LOGGER.info( "File has been uploaded." );
 this.state = STATE_COMPLETED;
 }
 }

 public String getState() {
 return state;
 }

 public List getUploadedFiles() {
 return uploadedFiles;
 }


 public String actionTest(){
 LOGGER.info( "action" );
 return null;
 }
}

I need your help :)

Hi,

It caused by changed value of 'rendered' attribute in your actionListener.

File upload action listener is invoking when file was transmitted to server. Then <a4j:support> on client determines that uploading has been completed and sends another ajax request to server. This request should invoke action defined in attribute of <a4j:support> component.
But 'rendered' attribute of fileUpload already has been switched to false. So, this request does not invoke action.

To solve the problem just place this code

this.state = STATE_COMPLETED;

to action method.
