How can a plugin return a specific error message for display at the GUI?1 follower
The SDK documentation shows that the main action of a plugin has to take place in a class which implements a ValueComputor interface. The methods which have to be implemented are compute(), computeIntermediate(), computeFinal(), etc. depending on the underlying interface type. The definition of these methods does not include any exception throwing. So, how can a plugin return a specific error message back to its caller so that it can be displayed at the GUI?
