jsf 2 - Adding query param breaks a4j:commandbutton -


i have following a4j:commandbutton has been working fine when on /page.xhtml:

<a4j:commandbutton action="#{controller.redirectpage()}"                    data-theme="b"  value="review"                    styleclass="ui-btn"                    onclick="log('opt')"                    onbegin="validate(event); $.efc.busy($.efc.messages.loading);"                    oncomplete="$.efc.busy('', true);" />

however after adding query param uri /page.xhtml?edit=true controller.redirectpage() never called. why query param break , how fix it?
