primefaces v3.5
trying use requestcontext.getcontext().scrollto("") scroll form programmatically @ end of ajax request.
xhtml snippets:
<h:form id="genericmessagesform"> <p:messages id="genericmessages" /> </h:form> <p:commandbutton id="testbutton" value="test" process="#{cc.attrs.itemname}final, @this" actionlistener="#{mybean.methodcalledbyajax()}" /> bean:
public void methodcalledbyajax() { list<string> updatetargets = new arraylist<string>(); updatetargets.add("currentrecordform"); updatetargets.add("genericmessagesform"); requestcontext.getcurrentinstance().update(updatetargets); requestcontext.getcurrentinstance().scrollto("genericmessagesform"); } update does work.
scrollto does not work (same id!).
no server errors thrown.
no javascript console errors thrown.
browsers tried: firefox (latest), chrome (latest), ie8.
did in documentation? here's cite requestcontext#scrollto() javadoc:
scrollto
public abstract void scrollto(string clientid)scroll component after ajax request completed.
parameters:
clientid- client side identifier of component.
look, says client id, not component id. makes sense, scrolling job done javascript via document.getelementbyid() , friends. works client id.
for starters haven't memorized whole namingcontainer thing, easy way figure right client id looking @ jsf-generated html output via rightclick, view source in webbrowser.
for
<h:form id="genericmessagesform"> <p:messages id="genericmessages" /> </h:form> that's like
<form id="genericmessagesform" ...> <div id="genericmessagesform:genericmessages" ...> ... </div> </form> so, fix call accordingly:
requestcontext.scrollto("genericmessagesform:genericmessages"); by way, if form contains solely <p:messages>, can alternatively rid of whole form altogether. <p:messages> not editablevalueholder nor actionsource component , therefore not require placed in uiform component. way can keep using initial attempt.
