Hi,
I am trying to upgrade from ZK 5.0.1 to 5.0.5 and encountered a problem with my dynamic images:
I create a set of images within a groupbox. When the user double-clicks on an image, it is moved into a second groupbox and a new set of images appears to choose from. It works fine with 5.0.1, but with 5.0.3 and 5.0.5 the first groupbox (the images to choose from) is not always updated correctly - old images are used rather than the newly created ones.
Any help is greatly appreciated,
meh
Here is the zul file:
choicesAreaChildren;
List choicesAreaKids;
int numChoices = 4;
String correctChoicesValue = "";
choicesAreaChildren = choicesArea.getChildren();
choicesAreaKids = new ArrayList();
// copy the list to prevent ConcurrentModificationException
for (Component comp : choicesAreaChildren) {
choicesAreaKids.add(comp);
}
// clear current choices
for (Component comp : choicesAreaKids) {
if ((comp.getClass() == Image.class) || (comp.getClass() == Space.class)) {
comp.detach();
}
}
// generate a new set of icons with the next numChoices numbers
for (int i = 0; i < numChoices; i++) {
anImage = new Image();
anImage.setContent(newimg((odd1 = !odd1), cnt));
anImage.setTooltiptext("image number: " + cnt);
correctChoicesValue += cnt + " ";
cnt++;
anImage.setDraggable("true");
anImage.addEventListener(Events.ON_DOUBLE_CLICK, new EventListener() {
@Override
public void onEvent(Event event) throws Exception {
DropEvent dropEvent = new DropEvent(Events.ON_DROP, pickedArea, event.getTarget(), 0, 0, 0, 0, 0);
Events.sendEvent(dropEvent);
}
});
aSpace = new Space();
aSpace.setSpacing("10px");
choicesArea.appendChild(anImage);
choicesArea.appendChild(aSpace);
}
correctChoices.setValue(correctChoicesValue);
}
public void onDrop$pickedArea(DropEvent evt) {
Space aSpace;
Image toolImg = (Image) evt.getDragged();
move(evt.getTarget(), evt.getDragged());
toolImg.setDraggable("false");
aSpace = new Space();
aSpace.setSpacing("10px");
evt.getTarget().appendChild(aSpace);
updateNextArea();
}
private void move(Component dropTo, Component dragged) {
dropTo.appendChild(dragged);
}
}
