Hi all.
It would be nice if I could catch CapabilityDisabledException on the client
in the RPC calls onFailure callback methods but it appears it isn't
possible; seems like the exception can only be declared in server code so I
came up with another solution and would like your feedback.
I am thinking about defining a custom exception derived from Throwable and,
sharing it between the client and server. I'd catch
CapabilityDisabledException in my RPC methods and in response I would throw
my custom throwable exception back to the client. In my client's RPC
onFailure callback methods I would catch my custom exception in the
following manner:
@Override
public void onFailure(Throwable caught) {
try{
throw caught;
}catch (MyCapabilityDisabledException e) { *<<===
catch it here**
* // direct the user to a view which explains
that the db is not available and to try again later
}
}catch(IncompatibleRemoteServiceException e){
}catch (InvocationException e){
}catch (Throwable e) {
Window.alert("Severe error!");
}
}
What do you think, do you like the solution or do you have a better one that
you have implemented and successfully tested and used?
Thanks in advance for your feedback.
