How to catch Exception in backingbean which is thrown from the Model layer.

Question

Hi,
JDev Ver: 11.1.1.2.0
In my application there are two layer viewcontroller & model.
In model layer I have created JPA service facade which does the database operation like persist, merge & remove entity.
I am calling this service facade method from backing bean via below standard code.
public static Object invokeMethod(String methodName, String mapKey,
Object object){
BindingContext bcx =
DCUtil.getBindingContext((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest());
JUFormBinding bc1 = (JUFormBinding)bcx.getCurrentBindingsEntry();
FacesCtrlActionBinding reassignOperationBinding =
(FacesCtrlActionBinding)bc1.findControlBinding(methodName);
if (mapKey != null && object != null) {
Map params = reassignOperationBinding.getParamsMap();
params.put(mapKey, object);
Object result = reassignOperationBinding.execute();
return result;
This is a static method which I am calling from backingbean to invoke service facade persist, merge or remove entity method
I have written throws in all the methods signature of service facade.
The exception which is thrown from the service facade are not comming back to backingbean catch block.
Is there any way to catch this exception in backingbean.
regards,
devang

Hi,
2 things to check
1 - does reassignOperationBinding has errors. You can check on the component
2 - does the exception show on the binding layet. See the Fusion Developer guide for how to define an error handler on the databindings.cpx file
