Gmap3 NullPointerException
Hi all,
I have set up this to report errors
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", "");
Regards
VIshal

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

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

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.
