Hi there,

I think perhaps I'm not currently using this component apropiately. My intention is to generate a file for download. I've used this:

<ice:outputResource attachment="true" styleClass="botoimprimir" renderedOnUserRole="DISTRIBUCIO"
label="#{lit.exportarExcel}" shared="false" fileName="informeAnual.csv"
resource="#{informes.informeAnualCsv}"
rendered="#{!empty(informes.informeAnual.linies)}"/>

It works. But as I have a log on the method getInformeAnualCsv from the 'informes' backing bean I can see that the method is invoked also on each rendering which includes navigation on a table that is shown in the page. Which of course is quite a waste of CPU.

What I'm doing wrong?

Thanks!

Hi,
Try placing some partialSubmit="true" on some of those components that have nothing to do with your file. This is not 100% certain.

What you can also do is cache the .csv file so you don't have to generate it every time, but this still leaves the waste of bandwidth of sending it more than once...

Radu

Thanks for the answer. Sorry for the late response. Working on the issue but not prioritary right now. Will post any news. Thanks!
