My Apologies and thank you Thomas. This is perfect. I failed to see
that you had added the alternate code to the quote.

Thanks again.

Robert.

 Wouldn't it be easier to rewrite your openReportWindow in Java rather than

Re: how to pass hash map to native java script method

when I do a post from gwt, the generated html page is returned in an
object. there are 2 problems with this.

1. I want the browser to render the returned page
2. this report could be excess of 1GB.

OK, I'll try this.

Thanks

 Actually I don't think it's as simple as you'd think. Gwt java objects
 are pretty opaque to JSNI. Depending on what you need, i'd suggest
 using JSONObject as a replacement for HashMap. That should probably
 work for you.

how to pass hash map to native java script method

[rsutton]

I am trying to pass a Hashmap to a native method as can be seen below.
I have been unable to find any suitable example code. Any assistance
would be greatly appreciated.

I know this is simple, I just haven't done it before.

Thanks.


public void onClick(ClickEvent event)
{
MapString, String params = new HashMapString, String();
params.putAll(definition.getParams());

   this is where my problem is, how to convert the params
object to a suitable
   object to work with the native openReportWindow method

openReportWindow(definition.getReportServletName(), params);
}

private static native void openReportWindow(String action,  values) /*-
{
   var form = document.createElement(form);
   form.setAttribute(method, post);
   form.setAttribute(action, action);


   // setting form target to a window named
'formresult'
   form.setAttribute(target, _blank);


   for (var i=0; ivalues.length; i++) {
var hiddenField = document.createElement(input);
hiddenField.setAttribute(name, values[i].name);
hiddenField.setAttribute(value, values[i].value);
form.appendChild(hiddenField);
   }
   document.body.appendChild(form);
   form.submit();
   document.body.removeChild(form);
   }-*/;
