> The HtmlCommandJSCookMenu component renders its own html-form called linkDummyForm. If
it is embedded into another form the other form (including its children) will never be decoded
because its submitted-property is set to false in UIForm.decode().
> It should be possible to control wether the HtmlCommandJSCookMenu component should render
its own form or should be part of an existing form.
> In my application I developed a solution for this problem.
> 1. The HtmlJSCookMenuTag needs a new property, which holds the id of the form which is
the parent of this tag. I called it formId. This new property has to be added in HtmlJSCookMenuTag.setProperties().
> 2. The HtmlCommandJSCookMenu component needs the formId property, described in step 1,
aswell. And it has to be added to saveState() and restoreState()
> 3. The HtmlJSCookMenuRenderer has to read the formId of its component. 
> 3.1 If it is not set everything stays as it is in the moment. That means: DummyFormResponseWriter.writeDummyForm
is set to true, which causes the writer to append a linkDummyForm at the end of the rendered
html page.
> 3.2 If it is set writeDummyForm of DummyFormResponseWriter is set to false. Instead of
rendering a form (called linkDummyForm) at the end of the rendered html page, there are only
two input-fields, which will be rendered within HtmlJSCookMenuRenderer.encodeChildren(): jscook_action,
which holds the choosed actionstring from the menu (in the moment it is rendered as part of
the linkDummyForm only) and a new field named jscook_form_id which gets the formId of the
HtmlCommandJSCookMenu component.
> 4. The cmItemMouseUp function within the JavaScript library named JSCookMenu.js needs
to read the jscook_form_id field, rendered previously in step 3.2 like this:
> -------begin code--------------------------------------------
> var formId = null;
> var dummyForm = null;
> var inputFormIds = document.getElementsByName('jscook_form_id');
> if (inputFormIds.length > 0) {
>   formId = inputFormIds[0].value;
>   dummyForm = document.forms[formId];
> } else {
>   dummyForm = document.forms['linkDummyForm'];
> }
> dummyForm.elements['jscook_action'].value = link;
> dummyForm.submit();
> ------------end code-------------------------
> 5. Moreover it is needed to configure the immediate attribute of the component in the
HtmlJSCookMenuTag. In the moment it is hardcoded in HtmlCommandJSCookMenu. There exists another
issue here in the database concerning this point.
