Hi there,

I am using v3.5.2

Despite setting the persisted parameter to true, the state isn't stored between two sessions.

Here is how I define the command:

      <command
            defaultHandler="xyz.example.commands.menuColumns.NameHandler"
            id="xyz.example.commands.menuColumns.name"
            name="Name">
         <state
               class="org.eclipse.ui.handlers.RegistryToggleState"
               id="org.eclipse.ui.commands.toggleState">
            <class
                  class="org.eclipse.ui.handlers.RegistryToggleState">
               <parameter
                     name="persisted"
                     value="true">
               </parameter>
            </class>
         </state>
      </command>

And here some code of the menu contribution part:

<command
                     commandId="xyz.example.commands.menuColumns.name"
                     label="Name"
                     style="toggle">
               </command>

Any help will be appreciated!

There doesn't appear to be anything wrong with your XML, and a brief examination of the code seems to indicate that it was available in 3.5.x. Here's an example to look at:

      <command
            categoryId="org.eclipse.ui.category.edit"
            defaultHandler="org.eclipse.example.commands.MonitorCountHandler"
            id="org.eclipse.example.commands.monitorCount"
            name="Monitor Count">
         <state
               class="org.eclipse.ui.handlers.RegistryToggleState:false"
               id="org.eclipse.ui.commands.toggleState">
         </state>
      </command>

and then in the toolbar something like:

            <command
                  commandId="org.eclipse.example.commands.monitorCount"
                  icon="images/collapseall.gif"
                  style="toggle">
            </command>

The handler then uses org.eclipse.ui.handlers.HandlerUtil.toggleCommandState(Comma nd) to work with the command State object.

The example is at https://github.com/paulweb515/commandsEclipseCon2011 in the org.eclipse.example.commands plugin.
