Launch wizard from Active Help page in Eclipse

问题

I'm creating an RCP application and wanted to provide documentation using the Eclipse Help Contents (Help > Help Contents), I managed to add some pages to it by using the extension point org.eclipse.help.toc, this works fine, but I'm interested in providing a link in one of those pages to launch a wizard, I found that Eclipse provides support for this using a feature called Active Help.

First, in my html Help page I have imported the livehelp.js script:

<head>
    ...
    <script language="JavaScript" src="PLUGINS_ROOT/org.eclipse.help/livehelp.js"></script>
<head>

Then in the <body> I added a link:

<a href='javascript:liveAction("com.test.my.plugin", "com.test.my.plugin.actions.TestAction", "")'>Execute action</a>

And finally, this my TestAction class:

public class TestAction implements ILiveHelpAction {

    @Override
    public void run() {
        System.out.println("Action executed");
        // code to launch wizard is here
    }

    @Override
    public void setInitializationString(String str) {

    }
}

But when the link is clicked the action is not executed, I tried setting a breakpoint in the run() method but it is never called, any idea why this is happening?
