May the same UICommand component prepare dataExporter's data source and trigger the dataExporter to get the XLS file?

[rosière]

Hello,
I would like my command link to achieve 2 goals after one click:
1. call a backing bean method in action attribute to fill the list of data to dump.
2. trigger data Exporter to download the data file.

Howeve this seems impossible.
I also tried to trigger programmatically with JQuery a commandButton that encapsulates data Exporter.
but it never went into effect.

So is my presumption reasonable? Thanks

Code: Select all

                   <p:dataTable id="myList" value="#{myBean.list}" >
....
 <p:commandLink action="#{myBean.fillList}"
                                           update="myPanel" oncomplete="$(button[id*='exporterLink']).submit();" />
                            <p:commandButton id="exporterLink" ajax="false" rendered="#{service.showExportLink}" oncomplete="alert('We will now trigger exporter...');"
                                             widgetVar="exporterLink" styleClass="NoDisplay">
                                <p:dataExporter type="xls" target="myList" fileName="detailedServices" />  
                            </p:commandButton>

I don't see any reason why it should not work from the oncomplete. Just make sure you have the right selector and do a 'click()' instead of submit(),
