Following the gvNIX reference document, there is a geo component for the layer opacity control that is added by including the following tag in the show.jspx view of the map
<geo:toc-toolbar id="ps_org_cite_pese_web_Mapa_toc_toolbar"
z="user-managed">
<tool:opacity id="opacity_slider" z="user-managed" />
</geo:toc-toolbar>
inside the toc-toolbar toolbar. To my basemap I added two more WMS layers that I would like to have that component as well. I would like to know if it is possible or if I am doing the inclusion in some wrong way, my code is the following.
<geo:toc id="ps_org_cite_pese_web_Mapa_toc"
z="+MeANZ7lrQ3PHfF88iYJKjjbAyE=">
<geo:toc-toolbar id="ps_org_cite_pese_web_Mapa_toc_toolbar"
z="user-managed">
<tool:opacity id="opacity_slider" z="user-managed" />
</geo:toc-toolbar>
