I am reading in a file, parsing it on the server, then storing data
into an object. I then pass the object back to the client, but i keep
getting an error:
com.google.gwt.dev.shell.HostedModeException: Something other than an
int was returned from JSNI method
'@com.google.gwt.user.client.rpc.impl.ClientSerializationStreamReader::readInt()':
JS value of type undefined, expected int
I dont have any int values in the object. Both classes are serialized
because i am using RPC calls.
I add an array of doubles to a list that is part of the object, if i
remove List.add(doubles[]) it works successfully, but doesnt return
any data from my object.
Here is an excerpt from my code, where the issue is happening (server
Side) -> returning to client
while ((inputLine = in.readLine()) != null)
{
String[] fName = new String[1];
double[] newPolygonCoords = new
double[8];
if(inputLine.equals("<coordinates>") ==
true)
{
String newPolyLine =
in.readLine();
String[] one =
newPolyLine.split(",");
fName[0] = one[0];
System.out.println(fName[0]);
String newPolyLine1 =
in.readLine();
String[] two =
newPolyLine1.split(",");
newPolygonCoords[0] =
Double.parseDouble(two[0]);
System.out.println(newPolygonCoords[0]);
newPolygonCoords[1] =
Double.parseDouble(two[1]);
System.out.println(newPolygonCoords[1]);
String newPolyLine2 =
in.readLine();
String[] three =
newPolyLine2.split(",");
newPolygonCoords[2] =
Double.parseDouble(three[0]);
System.out.println(newPolygonCoords[2]);
newPolygonCoords[3] =
Double.parseDouble(three[1]);
System.out.println(newPolygonCoords[3]);
String newPolyLine3 =
in.readLine();
String[] four =
newPolyLine3.split(",");
newPolygonCoords[4] =
Double.parseDouble(four[0]);
System.out.println(newPolygonCoords[4]);
newPolygonCoords[5] =
Double.parseDouble(four[1]);
System.out.println(newPolygonCoords[5]);
String newPolyLine4 =
in.readLine();
String[] five =
newPolyLine4.split(",");
newPolygonCoords[6] =
Double.parseDouble(five[0]);
System.out.println(newPolygonCoords[6]);
newPolygonCoords[7] =
Double.parseDouble(five[1]);
System.out.println(newPolygonCoords[7]);
}
newFileList.add(fName);
the
error goes away if i remove these two lines
newPolyList.add(newPolygonCoords);
}
in.close();
srv.setPolyList(newPolyList); the error goes
away
if i remove these two lines
srv.setFNameList(newFileList);
return srv;
Thanks for any advivce
