Swing not repainting when I run the .jar except in command prompt

Question

I have a project with a lot of panels. I have one method that switches the card (jpanel) in a card layout panel (see below). This all works fine when I run it from my IDE (Netbeans) and when I run the jar from command prompt (java -jar MyStuff.jar). But when I double click the Jar the card changes but doesn't repaint producing undesireable results (when I mouse over the components appear). If I call the method again by clicking the button again it'll apply. I need help immediately please :) Thanks!

/**
* Shows a panel by the given panel name (in the cardPanel)
*
* @param panelName
*/
private void showPanel(String panelName) {
  if (panelName.equals("revenueSources")) {
    backButtonIcon.setVisible(false);
  } else {
    backButtonIcon.setVisible(true);
  }
  currentPanelName = panelName;
  ((CardLayout) cardPanel.getLayout()).show(cardPanel, panelName);
  repaint();
  revalidate();
}

very well, could be nice question in the case edit your question with [SSCCE](http://sscce.org/) — mKorbel, Apr 07 '12 at 14:49
This [SSCCE using `CardLayout`](http://stackoverflow.com/a/5786005/418556) works without calling `repaint()`, `revalidate()` *or* `validate()`. I can only conclude that your code is very wrong. But I'll reserve further comment for ***your*** SSCCE. — Andrew Thompson, Apr 07 '12 at 14:56
You're right, I'm wrong to not use SSCCE. I just don't have time and in a few hours it wont matter. I'll just use a bat file to run it instead. Thanks for the help. — kentcdodds, Apr 07 '12 at 14:59
If you don't have the time to create an sscce, then neither do we. Best of luck. — Hovercraft Full Of Eels, Apr 07 '12 at 15:40

(when I mouse over the components appear) for this code only swap from

repaint();
revalidate();

to

revalidate();
repaint();

@kentcdodds: if it didn't work, then you may wish to create and post your [sscce](http://sscce.org). – Hovercraft Full Of Eels Apr 07 '12 at 15:19
+1, I will go with the answer :-), just couldn't understand the call to `repaint()/revalidate()` by OP, that too in CardLayout :-) – nIcE cOw Apr 07 '12 at 17:26
