rf4 a4j:mediaOutput event oncomplete

[tatatanja]

Hi,

i have a mediaOutput which creates an Excel-Sheet. On event onclick I show a popupPanel which has a progressbar. When the export is finished I want to hide the popupPanel, but a4j:mediaOutput has no event oncomplete.

Has anyone an idea how i can hide the popupPanel?

My code:

<a4j:mediaOutput element="a" createContent="#{exportController.getExcelFile}" cacheable="false" id="createExcel"
     value="test.xls" mimeType="application/csv" styleClass="btnList" onclick="#{rich:component('inProgressPanel')}.show();">
     <h:outputText value="download excel" />
</a4j:mediaOutput>

<rich:popupPanel modal="true" id="inProgressPanel" width="500" height="150"
        resizeable="false" moveable="false" >
        <f:facet name="header">
            <h:panelGroup>
                Bitte warten...
            </h:panelGroup>
        </f:facet>
        <div align="center">
            <p>
           Download!
            <rich:progressBar mode="ajax" enabled="true" maxValue="100" value="99.9">
                ...loading ...
            </rich:progressBar>
            </p>
        </div>
    </rich:popupPanel>

Greets, Tanja

Hi,

the progressbar has an onfinish attribute, you can use that.

I tried it, but the Panel didn't close. My method is started with the a4j:mediaOutput and so the progressBar don't know when the method is finished...

Any other Idea?

I thought the progressbar was there to monitor the progress. You could define a data attribute pointing to some variable that will be set to true once the export finishes.

<rich:progressBar data="#{exportController.exportFinished}" onbegin="if(event.data){#{rich:component('inProgressPanel')}.hide();}">
