How to transmit parameter (or more) between an ActionEventextended class and a Screen extended class?

[Chappuis J.-Vincent]

Hi! I need assistance.   Question:   How to transmit parameter (or more) between an ActionEvent extended class and a Screen extended class? I tested to transmit a parameter via "RunData" but it doesn't work :   Description that I have tested :   ActionEvent.doSavesoft(RunData data) { int identifient = 5; [...] data.getParameters().add("identifient", identifient);  [...] identifient=data.getParameters().getInt("identifient"); <--here, identifient has the right value : 5 ! }   And then...   Sceen.doBuild(RunData data) { int identifient; [...] identifient=data.getParameters().getInt("identifient");  <--here, identifient value is null ! Why? Does data isn't persistant? [...] }   Any idee?
