Palette-base component not showing

[Davor Miku]

Hi,

Palette-base custom component "category.palette" is not showing when
embedded into beaneditform:

<t:beaneditform t:id="content" exclude="id">
    <t:parameter name="categories">
        <t:category.palette t:id="categories"
t:currentCategories="content.categories" />
    </t:parameter>
</t:beaneditform>

Otherwise it woks fine. There is no exception. PRODUCTION_MODE is set to
false.

Can anyone help, please?

I'm pretty new to Tapestry, sorry if I'm making dumb questions.
