Re: Reference Error

Hello Mike,

first of all thanks for your help and sorry for the late reply.

I will try to add more meat to my problem description:

What I have is two classes, named Article and MonitoredItem, with Article being the superclass of Monitored item.
The corresponding two lines (defining the converters) inside the dwr.xml look like the following:

<convert match="foo.bar.Article" javascript="Article" converter="bean"/>
<convert match="foo.thing.MonitoredItem" javascript="MonitoredItem" converter="bean"/>

Now one of the js files generated by DWR lets Firefox have the aforementioned exception. I attach the zipped .js file.

I also think that the definition of the subclass is missing but do not fully understand the generated file.

Thanks again for your help,
Florian

Specifically look for the definition of SubClass within the generated file. The error seems to indicate it is missing from the file, but normally the class definition and the prototype assignment (the problematic line) go hand in hand, albeit in different parts of the file.

No, it isn't, and we should be able to get your example working. Could you send along a somewhat larger snippet (10 lines before and after) of the generated code around the line with the error?

Best regards

Adding the subclass converter alone does work.
So is this a common practice NOT to include superclasses of classes already known to DWR?

Have you tried adding the subclass converter alone?

Hello,

when I add the following lines to my dwr.xml

<convert match="foo.bar.SuperClass" javascript="SuperClass" converter="bean"/>
<convert match="foo.bar.SubClass" javascript="SubClass" converter="bean"/>

where SuperClass is the SuperClass of SubClass, I see the following error in my Firebug console:

"ReferenceError: SubClass is not defined"

, referencing the line in the generated js (one of the files that have creators defined)

SubClass.prototype = new SuperClass();

Please excuse my blindness, but what am I doing wrong? I am using DWR 3.0rc1.

Thanks for your help,
Florian
