Problem with af:tableSelectOne / af:commandButton

Question

Hi,
I have an af:tableSelectOne and an associated af:commandButton 'Confirm' whos action is the method processLink() in the backing bean .
For the first page of table results, everything works as expected, however, for any subsequent page of table results selecting a row and clicking 'Confirm' submits the page but does not call processLink() ie does not hit my breakpoint. After the submission, clicking 'Confirm' hits processLink().
Why do I need to click the command button twice to hit its action?
Furthermore, if i set AutoSubmit to true on the af:tableSelectOne it solves the problem, but has the undesired side effect of submiting the page everytime a row is selected.
Any ideas?
Please let me know if further information is required.
Thanks.

Hi, I am newbie to JSF-ADF and face a similar problem. I am working off of Steve Muench's example ([http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#85]) and trying to add a download component to the page.
Below is a snippet of the download segment from the JSF page.
+<af:table value="#{bindings.LastFiveUploadsList.collectionModel}"+
+var="row" rows="#{bindings.LastFiveUploadsList.rangeSize}"+
+first="#{bindings.LastFiveUploadsList.rangeStart}"+
+emptyText="#{bindings.LastFiveUploadsList.viewable ? 'No rows yet.' : 'Access Denied.'}"+
+id="table1">+
+<f:facet name="selection">+
+<af:tableSelectOne binding="#{UploadFileToBlob.tableSelectOne}"+
+id="tableSelectOne1" />+
+</f:facet>+
+<f:facet name="actions">+
+<af:panelButtonBar>+
+<af:commandButton text="Download"+
+binding="#{UploadFileToBlob.downloadButton}"+
+id="downloadButton"+
+action="#{UploadFileToBlob.downloadAction}"/>+
+</af:panelButtonBar>+
+</f:facet>+
+<af:column headerText="#{bindings.LastFiveUploadsList.labels.Filename}"+
+<af:outputText value="#{row.Filename}"/>+
+</af:column>+
+</af:table>+
And in the managed bean:
+public String downloadAction() {+
+DCIteratorBinding Iter = ADFUtils.getIterator("LastFiveUploadsList");+
+Row r = Iter.getCurrentRow();+
+System.out.println((String)r.getAttribute("Filename"));+
+}+
Irrespective of the selection from the list for download, the "r.getAttribute('Filename") always returns the last uploaded file.
What am I missing here? Thanks.
