Martin,
I could not find any help using this extension. May be I missed something
somewhere.
Let's look at a peice of code of what I am trying to do:
private void setScreen(String screen) {
try {
Panel myPanel;
myPanel = (Panel)
Class.forName("com.mycompany.components."+screen).newInstance();
screenPanel.replaceWith(myPanel);
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
So assuming I need to display a screen called "EditUserScreen", I need
to load
myPanel = (Panel)
Class.forName("com.mycompany.components.EditUserScreen").newInstance();
With the above code everything works fine. But Nothing is replaced. I
mean it executes with with no error, but the new panel is not shown. One
more thing to mention, if I add additional components in the
EditUserScreen Panel class, without adding them in the html, I see NO
error generated ! Is't correct to conclude that the html template for
EditUserScreen is never parsed, and instead the Panle.java is used ?
Shouldn't the old panel should be removed in this case, at least?
