I would need to create global actions that can change state in the time, but don't depend on any editor or view. The actions can be in two states:
index.php/fa/7503/0/

or:

When I define the action with class attribute:

          <action
                class="com.gooddata.clover.designer.actions.SignInAction"
                id="com.gooddata.clover.designer.action.SignIn"
                label="%authorization_sign_in"
                menubarPath="com.gooddata.clover.designer.Server/Server">
          </action>

the label and state can't be changed dynamicaly. But, when I mark the action as "retarget" I can add it to the editor or view only.
What is the proper way of handling such situation?

AFAIK it's not possible to do with out-dated Actions. Actions are considered out-dated, checkout Commands Framework instead. In case of Command Frameworks it is achievable with

<extension point="org.eclipse.ui.menus">
    <menuContribution
          allPopups="false"
          locationURI="menu:com.virtage.plexflow.menu.file?after=additions">
          
          <command
             commandId="com.virtage.plexflow.ui.explorer.NewContainer"
             label="New folder...">
             
             <!-- visible when Explorer editor is focused -->
             <visibleWhen>
                <with variable="activePartId">
                      <equals
                            value="com.virtage.plexflow.ui.explorer.ExplorerEditor">
                      </equals>
                </with>
             </visibleWhen>
             
       </command>
    </menuContribution>
    ...

There's a lot of possible <visibleWhen> conditions that are made win use of so-called core expressions.

Thank you for answer. This way I'm able to control enability of the menu item, but I'm not able to change the label Sad

Is it possible to provide "visibleWhen" programatically? If it would be possible I could create more diffrent actions and show the one with label I need. But I have no idea how to implement visibleWhen, with the current state of my object.

At last I've found that it is piece of cake: all I need is to add a dynamic element that implements IContributionItem to my menu. Then I can change the label as well as enablement.
