Pass tables values

Question

Hi...
I am trying to call  an external function in R/3 via WebDynpro.  The function uses a table with associated type W3Query. I execute the function in R/3 by adding name/value pairs to the table.
In WebDynpro, I am setting the same values in table.
When I execute the function, an exception is thrown by the program that indicates that the parameters aren't present.
However, the parameter data is being displayed from the context on my output screen.  Any suggestions on how to pass the parameters would be appreciated.....
In the init method, I am binding the input and output:
Www_Get_Report_Input wgri = new Www_Get_Report_Input();
    Www_Get_Report_Output wgro = new Www_Get_Report_Output();
    wdContext.nodeWWW_GET_REPORT().bind(wgri);
    wdContext.nodeOutput().bind(wgro);
In the implementation for testing, I am binding the Query String table:
Vector v = new Vector();
W3Query w3q1 = new W3Query(wdContext.currentWWW_GET_REPORTElement().modelObject().modelInstanceId());
w3q1.setName("_REPORT");
w3q1.setValue("ZM1BOMX2");
v.add(w3q1);
wdContext.nodeQuery_String().bind(v);
W3Query wqnew = new W3Query(wdContext.currentWWW_GET_REPORTElement().modelObject().modelInstanceId());
try {
wdContext.currentWWW_GET_REPORTElement().modelObject().execute();

hello Stephen
instead of creating a Vector object you create the objects of ur internal table that you want to pass ( here i think its "W3Query" )
ie W3Query obj = new W3Query();
   obj.setName("_REPORT");
   obj.setValue("ZM1BOMX2");
   wgri.addW3Query(obj); // wgri is ur  "Www_Get_Report_Input" object.
repeate this in a loop for "n" no. of records. hope this will help u. no need of creating " Www_Get_Report_Output" object.
