when i use flexgrid 

$("#flex1").flexigrid
({
    url: '../application/recommendList',
    dataType: 'json',
    mehtod:'post',
    colModel: [
    { display: 'ISBN', name: 'isbn', width: 130, align: 'center' },
    { display: 'title', name: 'title', width: 130, align: 'center' },
    { display: 'aujthor', name: 'author', width: 130, align: 'center' },
    { display: 'publisher', name: 'publisher', width: 120, align: 'center' },
    { display: 'date', name: 'date', width: 105, align: 'center' },
    { display: 'status', name: 'status', width: 40, align: 'center' },
    { display: 'detail', name: 'status', width: 40, align: 'center' }
    ],
    sortname: "isbn",
    sortorder: "asc",
    usepager: true,
    striped: true,
    useRp: false,
    rp: 10,
    width: '778',
    height: 255,
    onError: function(XMLHttpRequest, textStatus, errorThrown){
    alert(textStatus)
        alert(XMLHttpRequest.responseText)
    }
});

the flexigrid.pack.js
$.ajax( {
type : p.method,
url : p.url,
data : param,
dataType : p.dataType,
success : function(data) {
g.addData(data)
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
try {
if (p.onError)
p.onError(XMLHttpRequest, textStatus,errorThrown)
} catch (e) {
}
}
})

when i delete the param data : param, everthing is ok

maybe there is something about data
in other word, is there some null param in the data param

If you use json plugin for struts you may define the result type 'input' in 
your strutx.xml

Ex.:

<action name="yourActionUrl"
            class="your.full.classPath" >
            <result type="json" name="input">
                            .... your params ....
            </result>
            <result type="json">
                            .... your params ....
            </result>
        </action>
