gwt - Why PlaceRequest doesn't work normally as we expected (GWTP)? -

-

i using gwtp. there method openurl following:

public void openurl(int key){      placerequest request = new placerequest(nametokens.search).with("showdata", "y");      if(key==1){          request.with("firstvariable","2154");      }      else if(key==2){          request.with("secondvariable","4454");      }      string url =   window.location.createurlbuilder().sethash(placemanager.buildhistorytoken(request)).buildstring();      window.open(url, "_blank", null); }

there button call openurl(1), after clicking button open url in form:

abc.com#search;showdata=y

clearly above url missing firstvariable param part.

the correct url should be

   abc.com#search;showdata=y;firstvariable=2154

i don't know why gwtp didn't read request.with("firstvariable","2154"); part expected.

can find out solution?

request.with(param, value) returns new placerequest, so

request = request.with("firstvariable","2154");

is need.
