Sergey Derugo updated WICKET-1919:
----------------------------------
Description:
1. Create any components that is derived from MarkupContainer, for example,
create Panel.
2. Put some components to the Panel, for example, TextInput, Label etc.
3. Call panel.setEnabled(false)
Result: all controls on panel are still disabled.
Notes: after some investigation I found that MarkupContainer doesn't override
setEnabled and therefore it cannot enable/disable components stored in the
container.
Workaround: manually disable all components that are displayed on the panel,
for example:
public void setEnabledForChildren(boolean enabled) {
setEnabledRecursive(this, enabled);
}
private void setEnabledRecursive(MarkupContainer container, boolean
enabled) {
Iterator<? extends Component> iterator = container.iterator();
while (iterator.hasNext()) {
Component component = iterator.next();
component.setEnabled(enabled);
if (component instanceof MarkupContainer) {
setEnabledRecursive((MarkupContainer) component, enabled);
}
}
}
I think that MarkupContainer must be responsible for disabling/enabling child
components.
