How to open a classical Notes document in a new client tab, triggered by a XPage -

i have implement following request, tries failed:

if click on button/link in xpage (xpinc), classic notes-document shall created in notes database. new notes document has open in new client tab beside tab xpage.

i’ve tried several ways with

facescontext.getcurrentinstance().getexternalcontext().redirect("notes://server/anotherdb/newdocumentunid?opendocument") 

but none of them led desired result (there 3 tabs opened or xpage tab empty).

edit:

it possible execute csjs ssjs view.postscript().

    <xp:button value="client" id="button3">         <xp:eventhandler event="onclick" submit="true" refreshmode="partial" disablevalidators="true">             <xp:this.action><![cdata[#{javascript:var url = myjavaclass.createnewdocumentandreturnnotesurl(); view.postscript("window.open('" + url + "')");}]]></xp:this.action>         </xp:eventhandler>     </xp:button> 

csjs function window.open(url) executed ssjs after creating document in other database , getting url new document. way, code executed when button clicked , new document opens in new window.
