 Hi all,

 this.getRequestCycleListeners().add(new AbstractRequestCycleListener() {
 @Override
 public IRequestHandler onException(RequestCycle cycle,
 Exception e) {
 return new RenderPageRequestHandler(new PageProvider(new
 InternalError(e)));
 }
 });

 One of the types of errors I am continuously being reported is below. I
 cannot understand how to recreate this or why it is occurring.
 Any help would be appreciated.

 I am using Gmap3 6.7.0 with Wicket 6.7.0
 The line seems to refers to
 final String overlayId =
 request.getRequestParameters().getParameterValue(overlay.overlayId).toString().replace(overlay,
 );


For me this means that
request.getRequestParameters().getParameterValue(overlay.overlayId).toString()
returns null, and replace() fails with NPE.
Create a Pull Request and it will be in 6.10.

Hi Martin,

I am not sure on the resolution to this. I do not know why overlay.overlayId
would be null?

Me too.
Put a breakpoint and see what other parameters are sent to the server.
Maybe it is misspelled or something.
