Examples of org.apache.wiki.api.exceptions.ProviderException

org.apache.wiki.api.exceptions.ProviderException
This exception represents the superclass of all exceptions that providers may throw. It is okay to throw it in case you cannot use any of the specific subclasses, in which case the page loading is considered to be broken, and the user is notified.

                        //  Sanity check - shouldn't really be happening, unless
                        //  you mess with the repository directly.

                        {
                            throw new ProviderException("Attachment disappeared while reading information:"+
                                                        " if you did not touch the repository, there is a serious bug somewhere. "+
