Hi Sumit,
the bug seems to be related to the content of that method
/*
* Helper method used to simplify the construction of JsonRPC objects
*/
function JsonRpcObjectBuilder( methodName, methodArguments ) {
var args = [];
if(typeof(methodArguments) != "undefined") {
if(typeof(methodArguments) != "object") {
args = [ methodArguments ];
} else {
args = methodArguments;
}
}
return {
id : 1,
method : methodName,
params : args
};
}
inside the file WebServer/PWService/web/js/dev/paraview.js which you
can point to in your testing process instead of its parent compressed
one ParaViewWeb.js. Although, don't forget to add /dev/json2.js and
/dev/jsonrpc.js too when you are using the development version of the
js.
Once you figured out, what need to be done to prevent those extra "
around [] then you can either send me the full paraview.js or just the
diff so I can patch and update the ParaViewWeb repository.
Thanks for your help,
Seb
