I made a simple test form for post request testig.
My simple goal is: send POST request with 2 parameters, store server response in the instance (server just sends recieved parameters back to form, untouched)
<xf:model>
<xf:instance id="request" xmlns="">
<data>
<arg1>param1</arg1>
<arg2>param2</arg2>
</data>
</xf:instance>
<xf:instance id="response" xmlns="">
<null/>
</xf:instance>
<xf:submission id="post-instance"
method="put"
replace="all"
instance="response"
resource="adderPost.xq"
ref="instance('request')"
serialization="application/xml"
mediatype="application/xml"
includenamespaceprefixes=""
>
</xf:submission>
</xf:model>
</head>
<body>
<h1>XForm interaction with XQuery</h1>
<xf:input ref="instance('request')/arg1" incremental="true">
<xf:label>Arg1:</xf:label>
</xf:input>
<br/>
<xf:input ref="instance('request')/arg2" incremental="true">
<xf:label>Arg2:</xf:label>
</xf:input>
<br/>
<xf:output ref="instance('response')/result">
<xf:label> Response:</xf:label>
</xf:output>
<br/>
<xf:submit submission="post-instance">
<xf:label>Post</xf:label>
</xf:submit>
<p id="status"></p>
</body>
if I use parameter replace="all", as it shown in code above, server returns answer:
<?xml version="1.0" encoding="UTF-8"?>
<result>
<arg1>param1</arg1>
<arg2>param2</arg2>
</result>
but, if I use parameter replace="instance" instance="response"
this one occurs:
throw 'allowScriptTagRemoting is false.';
(function(){
var r=window.dwr._[0];
//#DWR-INSERT
//#DWR-REPLY
r.handleCallback("2","0",[{bubbles:true,cancelable:false,contextInfo:{"resource-uri":"http://10.40.171.50:8080/exist/apps/RBS_path/adderPost.xq",

})();

If you want to replace an instance replace="instance" is the way to go, by using replace="all" you will replace the whole page. Also I noticed you use method="put", if you want to POST you should use method="post".
See http://pastebin.ubuntu.com/11908113/ (xforms) and http://pastebin.ubuntu.com/11908115/ (xquery) for a working example.
