Command [message #655800]

I'm testing seriously the command framework, to get rid of Actions, and having just one way of doing things.

The problem I have is that I have a command with a toggle state:

<command
categoryId="com.jobisjob.crud"
id="com.jobisjob.crud.lock"
name="Bloquear cambios">
<state
class="org.eclipse.ui.handlers.RegistryToggleState:false"
id="org.eclipse.ui.commands.toggleState">
</state>
</command>

with a binding.
It appears in a toolbar and in a menu item in the main menu.

The problem is that when the toggle state changes, it isn't reflected on the other GUI items, i.e. when I click the toolbar, the menu item doesn't appear checked, and when I click the menu item, the toolbar icon doesn't appear checked.

My hanlder implements the IElementUpdater interface :

public void updateElement(UIElement element, Map parameters) {
element.setChecked(....);
}

How can this be solved?
Any suggestions will be very welcome.

David.

The state of the command is not updated automatically. Its the
responsibility of the handler. In your handler's execute method you need
to toggle and update the command's state
