Af:commandToolbarButton to open a link but not navigate away from taskflow

Question

I would like to be able to have the following
- a commandToolbarButton that when clicked upon downloads a document (by a simple URL call whos http response tells the browser to download the file, not open it)
- when click on the arrow on the right of the button, get a list of other download/open options for the document
To get a document/document rendition, we simply make a URL call, so the options in the command buttons drop down is simply goMenuItems that go the URL obtained from the backing bean. I want the same behaviour as a goMenuItem on the actual button when it is clicked on.
I have the following
<af:commandToolbarButton text="#{dlBndl.VIEWDOC_DOWNLOAD}" id="dlvtrm" >
<f:facet name="popup">
<af:menu text="" id="dlvtrm1">
<af:goMenuItem text="#{dlBndl.VIEWDOC_OPEN_NATIVE}" id="dlvtrm2"
destination="#{pageFlowScope.prprts.item.url}#{pageFlowScope.prprts.portletLinkPostfix}"
rendered="#{pageFlowScope.prprts.item.nativeFileWebViewable}"
targetFrame="_blank"/>
<af:goMenuItem text="#{dlBndl.VIEWDOC_OPEN_PDF}" id="dlvtrm3"
destination="#{pageFlowScope.prprts.item.webRenditionURL}#{pageFlowScope.prprts.portletLinkPostfix}"
rendered="#{pageFlowScope.prprts.item.webViewableAvailable}"
targetFrame="_blank"/>
</af:menu>
</f:facet>
</af:commandToolbarButton>
I can not work out how to have the button click go to a url like the goMenuItem's. I have tried adding an action to my taskflow and using that on my button, but its not working
<url-view id="downloadNativeFile">
<url id="dldv78">#{pageFlowScope.prprts.item.downloadNativeFileURL}</url>
</url-view>
<control-flow-case id="dldv82">
<from-outcome id="dldv83">downloadNativeFile</from-outcome>
<to-activity-id id="dldv84">downloadNativeFile</to-activity-id>
</control-flow-case>
Attempt 1:
<af:commandToolbarButton text="#{dlBndl.VIEWDOC_DOWNLOAD}" id="dlvtrm" action="downloadNativeFile">
when the button is clicked on, the file did ask to be saved, but then nothing else on my page works, i can not even click on the arrow of the button to see the drop down list of options
Attempt 2:
<af:commandToolbarButton text="#{dlBndl.VIEWDOC_DOWNLOAD}" id="dlvtrm" action="dialog:downloadNativeFile" useWindow="true">
Now when the button is clicked on nothing happens, the page doesnt break though.
Question: How do i get behaviour that when a user clicks on the actual commandToolbarButton it goes to a URL (like the goMenuItem) but does not break my page so i can carry on using my page.
I have tried having an action, and then in my taskflow to go to a URL view,
<af:commandToolbarButton text="Google"
action="goToGoogle">

Answer 1

i.e. with a goMenuItem/goLink you would have
<af:goMenuItem text=""DOWNLOAD file"
destination="http://download.oracle.com/docs/cd/E10316_01/ContentIntegration/Pdf/cis-administration-guide.pdf"
targetFrame="_blank"/>
<af:goLink text=""DOWNLOAD file"
destination="http://download.oracle.com/docs/cd/E10316_01/ContentIntegration/Pdf/cis-administration-guide.pdf"
targetFrame="_blank"/>
i.e. i would like to do the exact same thing for the commandToolbarButton when you click on it, as if it was
<af:commandToolbarButton text="DOWNLOAD file"
destination="http://download.oracle.com/docs/cd/E10316_01/ContentIntegration/Pdf/cis-administration-guide.pdf"
targetFrame="_blank"/>
