[OpenLayers-Users] Object required error in OpenLayers.Ajax.Request.respondToReadyState

[Vincent-Gabriel Vallée]

I'm getting an error with the following bit of code in OpenLayers\Ajax.js in the respondToReadyState function:

        ...
        try
        {
            (this.options['on' + event] || OpenLayers.Ajax.emptyFunction)(transport, json);
             OpenLayers.Ajax.Responders.dispatch('on' + event,this,transport,json);
>        }
        catch (e)
        {
            this.dispatchException(e);
        }
        ...

I'm using IE7 and trying to debug in VS2005 a GML layer not appearing and an 'Object required' error at the '>'.
