Can't create params for custom component - components

Question

I'm currently working on a custom joomla component but I fail to get the component wide parameters to work.
The joomla docs say that if you add
to your 'myComponent.xml' file, the parameter should appear in the _components table. I do see my component but there are no params there.
Is there anything I should know? Or anything I might do wrong?
here is test.xml { myComponent.xml }:
<?xml version="1.0" encoding="UTF-8"?>
<install type="component" version="1.5.0">
<name>test</name>
<creationDate>2010-08-05</creationDate>
<author>test</author>
<version>1.0.0</version>
<description>test</description>
<administration>
<menu>Ctest</menu>
<files folder="admin">
<filename>controller.php</filename>
<filename>test.php</filename>
<filename>index.html</filename>
<filename>models/test.php</filename>
<filename>models/index.html</filename>
<filename>views/index.html</filename>
<filename>views/test/index.html</filename>
<filename>views/test/view.html.php</filename>
<filename>views/test/tmpl/default.php</filename>
<filename>views/test/tmpl/index.html</filename>
</files>
</administration>
<params>
<param name="test" type="text" default="" label="test" description="test" />
</params>
</install>

Make sure you're configuring the params correctly in both places config is needed.
In COMPONENTNAME.xml, you need the block you've got above (although I think only 'name' and 'default' are used here).
Also, in admin/config.xml, you'll need something like:
<root>
<params>
<param type="text" name="test" size="30" label="test" description="test" />
</params>
</root>
You'll then need to make sure there's a way to get to these config options, with this in your 'toolbar.COMPONENTNAME.html.php':
JToolBarHelper::preferences('com_magentocatalogue');
Then, a 'config' button should appear in the toolbar for your component. Only once you save some changes will these parameters appear in the #__components.params field.
