XPages onclick event not submitting on NEW document -

i have xpage upon exists checkbox group control. have code defined onclick event submit value of checkbox managed bean on server, , trigger partial refresh of element.

this works fine when editing existing document.

however, when working new document, submit never fires.

here code:

<xp:checkboxgroup     id="cztypes1"     value="#{document1.cztypes}"     required="true"     layout="pagedirection">     <xp:this.validators>         <xp:validaterequired message="you must select @ least 1 employee type" />     </xp:this.validators>     <xp:selectitem         itemlabel="office"         itemvalue="o" />     <xp:selectitem         itemlabel="non-office"         itemvalue="n" />     <xp:selectitem         itemlabel="sub contractors"         itemvalue="s" />     <xp:eventhandler         event="onclick"         submit="true"         refreshmode="partial"         refreshid="alertrecipients1">         <xp:this.action><![cdata[#{javascript:alertmessage.echo(getcomponent("cztypes1").getvalue());}]]></xp:this.action>     </xp:eventhandler> </xp:checkboxgroup> 

any ideas?

ok, got answer friend on forum.

the issue had validators on other controls on xpage.
because lifecycle processing , failing validation (for other blank fields) onclick submittal portion not being processed.

this demonstrated adding immediate=true property event handler:

doing allowed testing proceed, , echo method called (with null value being passed due validation failure).

once other fields on xpage filled out, onclick event worked fine.
