Mapviewer demo mapinit.jsp with svg doesn't work with jdeveloper

Question

hi ng,
i tried the source code for the svg-sample in jdeveloper and first of all jdeveloper dislikes the line "<embed id="map" src="<%= mv.getGeneratedMapImageURL() %>...". after "embed" a green line is to be seen.
When i start the sample the map looks okay, but when i want to hide a theme (or zoom), i get the internet_explorer-message "error on the page".
"themeVisibleArray[idx]='false';" goes right but the next line occurs the error: "map.window.hideTheme(theme) ;"
map is not known at this place, it seems to me.
who can help (please)?
greetings
thomas

hi,
i still have a problem. i can work on an existing svg-map but not on a just generated svg-map. zoomin2 works.
here's the code:
