FiltersManager.getAllServices({
callback : updateServiceFilter,
errorHandler : function(message) {
alert(message);
}
});
Although I throw an exception when an error occurs in the backend, the error message always shows as "Error" when alerted.
Do I need to enable a specific setting for this to display the correct error message?
If an exception is not assigned a specific converter, the client will receive the exception object in this format:
{
javaClassName:'java.lang.Throwable',
message:'Error'
}
To display more detailed information about exceptions, add the following code to dwr.xml:
<convert match="java.lang.Exception" converter="exception"/>
By default, this configuration will attempt to convert all available data within the exception. The converted exception may look something like this:
{
javaClassName:'org.xml.sax.SAXParseException',
lineNumber:42,
publicId:'somePublicId',
message:'Missing >'
}
Have you considered examining the second parameter of DWR's errorHandler function?
errorHandler:function(errorString, exception) {
console.log(exception);
}
