Default value for radio button [message #516837]

I have a menu with a sub menu that contains three radio buttons. I want the third of the radio buttons checked by default (i.e. at program start). However, all three radio buttons are checked.
This is a snippet from my plugin.xml:

<extension
         point="org.eclipse.ui.menus">
      <menuContribution
            locationURI="menu:org.eclipse.ui.main.menu">
         <menu
               id="viewMenu"
               label="View">
            <menu
                  id="navigationMenu"
                  label="Connections">
	              <command
			            commandId="myApp.commands.navigationAll"
			            label="snap to road"
			            style="radio">
			         <parameter
			               name="org.eclipse.ui.commands.radioStateParameter"
			               value="all">

			      </command>
			      <command

			            label="direct connection"
			            style="radio">
			         <parameter

            </menu>

Why do you need three different commands. All you need is one command
with the parameter and three different contributions

Thanks for the quick answer. That's what I first thought, too. When I use only one command, no radio buttion is selected at the beginning. The snippet now looks like this:

<extension
         point="org.eclipse.ui.menus">
      <menuContribution
            locationURI="menu:org.eclipse.ui.main.menu">
         <menu
               id="viewMenu"
               label="View">
            <menu
                  id="navigationMenu"
                  label="Connections">
	              <command
			            commandId="myApp.commands.navigation"
			            label="snap to road"
			            style="radio">
			         <parameter
			               name="org.eclipse.ui.commands.radioStateParameter"
			               value="all">
			         </parameter>
			      </command>
			      <command
			            commandId="myApp.commands.navigation"
			            label="direct connection"
			            style="radio">
