When set the value of a 'val' ?

[gbasso]

The following code highlight an error (Assignment to final field) :

agent TransmitterAgent {
    val capacityValue : Double

    on Initialize {
        capacityValue = occurrence.parameters.get(0) as Double;
    }
}

Moreover an error occurs in the java code.

public class TransmitterAgent extends Agent {
  /**
   * Creates a new Agent of type TransmitterAgent
   */
  public TransmitterAgent(final java.util.UUID parentID) { // error
// Multiple markers at this line
//  - The blank final field capacityValue may not have been initialized

[ngaud]

val capacityValue : Double = 5 this is the only way to initialize a val inside an agent. Because val keyword is mapped to a final attribute in Java, and the Agent's constructor is not accessible to the user.

The various "on initialize" must be the constructors of the agent but currently there is no easy solution to do that.
