Hi,

I am using Richfaces 4.0.0.Final under Tomcat 7.0.

Here is the xhtml-part

<rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
    id="upload" 
    acceptedTypes="csv, zip"
    maxFilesQuantity="1">
    <a4j:ajax event="uploadcomplete" execute="@none" render="info" />
    <a4j:ajax event="filesubmit" execute="@form" render="info" />
    <f:facet name="progress">
        <rich:progressBar 
            interval="500" 
            id="pb"
            value="#{fileUploadBean.currentValue}"
            label="#{fileUploadBean.processed} of #{fileUploadBean.toProcess} processed.">
        </rich:progressBar>
    </f:facet>
</rich:fileUpload>

and here the fileUploadBean

import java.io.Serializable;
import javax.inject.Inject;
import javax.inject.Named;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.richfaces.event.FileUploadEvent;
import org.richfaces.model.UploadedFile;
import org.springframework.context.annotation.Scope;

import de.mbb.abgst.service.Loader;

@Named("fileUploadBean")
@Scope(value = "session")
public class FileUploadBean implements Serializable {
    private final static Log log = LogFactory.getLog(FileUploadBean.class);
    private static final long serialVersionUID = -4473074092916884407L;

    @Inject
    private Loader loader;

    private int lineCount = 0;
    public FileUploadBean() {
    }
    public void listener(FileUploadEvent event) throws Exception {
        UploadedFile item = event.getUploadedFile();
        lineCount = loader.countLine(item.getInputStream());
        log.info("Start loading ...");
        loader.load(item.getInputStream());
    }
    public int getProcessed() {
        log.info("getProcessed");
        int processed = loader.getProcessed();
        log.info("processed: " + processed);
        return processed;
    }
    public int getToProcess() {
        log.info("getToProcessed");
        return lineCount;
    }
    public int getCurrentValue() {
        int ret = 0;
        if (lineCount > 0) {
            ret = getProcessed()*100/lineCount;
        }
        return ret;
    }
}

Most of the time is spend on

loader.load(item.getInputStream())

Uploading takes just a couple of seconds, but the progressbar is filled after

uploading is processed.

I thought, I could overwrite the progressbar with own configuration, but the shown code has no effect.

Trying to put a separate progressbar would be also fine, but

<a4j:ajax event="filesubmit" execute="@form" render="info" />

is not firing (although an explicit onfilesubmit is firing) so that I can't enable the separate progressbar.

Any idea or best practice ?

Thanks and regards
