Hi there
Thats an interesting approach I've never actually called GWT methods
that way.
It looks like from your code that you're calling it that way because
you need to pass a parameter? Is this correct?
I think with GWT you have must have an entry point so that the script
gets loaded and that may be the reason you cannot access the
function?
In the past I have used a hidden div with inner content to pass
parameters to the GWT application like so:
<div id="myParamsDiv">
myParamValue
</div>
RootPanel paramsDiv = RootPanel.get("myParamsDiv");
String paramsText = DOM.getInnerText(paramsDiv.getElement()); //
paramsText would equal myParamValue
Then the entry point would run as normal?
Also have you tried debugging the script on Firefox using Firebug -
I'm aware that as it goes to the GWT script you wont be able to debug
that easily but you should be able to debug your callGWTUtils function
and you can check that all the variables exist?
