[pkg-j2se-devel] j2re1.4: send ItemEvent without user action

[Joan Queralt]

Subject: j2re1.4: send ItemEvent without user action
Package: j2re1.4
Version: 1.4.2.03-1
Severity: normal

The following code:

Choice _idioma;

(...)

   int totalIdiomes=Etiquetes.idiomes.length;
   _idioma.removeAll();
   for (int i=0;i<totalIdiomes;i++) {
      _idioma.add(Etiquetes.idiomes[_numIdioma][i]);
   }

generate some ItemEvent's that are sended to the Choice ItemListener's.
This differs from Sun Virtual Machine behaviour and from what the Sun
documentation says: "Class ItemEvent: This high-level event is generated
by an ItemSelectable object (such as a List) when an item is selected or
deselected by the user", because they aren't produced by user action.

The following code will work on Sun JRE but not on Blackdown:

Choice _idioma;

(...)

public void itemStateChanged(ItemEvent arg0) {
    _numIdioma=_idioma.getSelectedIndex();
    int totalIdiomes=Etiquetes.idiomes.length;
    _idioma.removeAll();
    for (int i=0;i<totalIdiomes;i++) {
        _idioma.add(Etiquetes.idiomes[_numIdioma][i]);
    }
}

because it leads to an infinite loop.

Please, contact me if this message isn't clear enough or if you need a
full code example.

Joan Queralt
