[CLOSED] direct method returns undefined value

[atroul]

Hello,
I have a direct method which gets 2 arguments and returns a value (string). While I can see that the direct method is called and the return value "result" is as expected (the alert function prints it with the correct value), the value in the HTML is 'undefined'

Handler="
    this.body.dom.innerHTML = String.format('{0}',(#{QueriesStore1}.getAt(rowIndex).get('PtId') !=null? #{DirectMethods}.callFNGetPtidPrfx(#{QueriesStore1}.getAt(rowIndex).get('SiteId'),#{QueriesStore1}.getAt(rowIndex).get('PtId'),{
                 success: function (result) {
                     alert(result);
                     return result;  
                 }
             }):'-')

The direct method:

[DirectMethod]
        public string callFNGetPtidPrfx(int siteid, int ptid)
        {
            DAL.CDataContext dc = new CDataContext(); //the arguments have the correct value here
            return dc.fn_GetPtid(100, siteid, ptid);
        }

Hello @atroul!

That's an assynchronous call. You have to bind the result to an outside variable during the success (or failure) function execution, it won't be returning anything at call-time.

In other words, you should rather

#{DirectMethods}.callFNGetPtidPrfx(#{QueriesStore1}.getAt(rowIndex).get('SiteId'),#{QueriesStore1}.getAt(rowIndex).get('PtId'),{
    success: function(result) {
        this.body.dom.innerHTML = result;
    }
});

instead of

this.body.dom.innerHTML = #{DirectMethods}.callFNGetPtidPrfx(#{QueriesStore1}.getAt(rowIndex).get('SiteId'),#{QueriesStore1}.getAt(rowIndex).get('PtId'),{
    success: function(result) {
        return result;
    }
});

Hope this helps!
