Re: [udig-devel] Catch and deal with rendering errors on mapview

[Jody Garnett <jody.garnett@xxxxxxxxx>]

The layer has recorded the last error; produced by the last attempt to
render it. If this value is non null a error icon appears on the
layer; and you can see the message when the layer is selected in the
status bar.

You can check this value yourself as a programmer; getStatusMessage;
and check if the layer is in error using getStatus() == Layer.ERROR
