I did it like this..
[snip]
@Property
private LETTER selectedLetter;
public LETTER[] getLetters() {
return LETTER.values();
}
@Inject
@Path("context:images/letters/")
private Asset pathPrefix;
public String getImagePath() {
return pathPrefix.toClientURL() + "/" +
selectedLetter.name().toLowerCase() + ".gif";
}
[/snip]
and in my tml
<t:loop source="letters" value="selectedLetter">
<t:linksubmit t:id="letterSubmit" context="selectedLetter"
border="0" defer="false">
<img src="${imagePath}" alt="${selectedLetter}"/>
</t:linksubmit>
</t:loop>
Hope that helps.
