Done it like this (in a grid, but that's basically the same):
implemented our own GridCell (copy-pasted all of AbstractPropertyEditor and
original GridCell for visibility reasons), but changed these two methods:
Object beginRender(MarkupWriter writer)
{
Object before = renderPropertyValue(writer,
getPropertyModel().getId()
+ "BeforeCell", false);
Object main = renderPropertyValue(writer,
getPropertyModel().getId()
+ "Cell", true);
Object after = renderPropertyValue(writer,
getPropertyModel().getId()
+ "AfterCell", false);
if (main instanceof BlockImpl)
{
BlockImpl bi = (BlockImpl) main;
BlockImpl result = new BlockImpl(bi.getLocation(),
"multiblock");
if (before != null && before instanceof BlockImpl)
{
result.addToBody((BlockImpl) before);
}
result.addToBody(bi);
if (after != null && after instanceof BlockImpl)
{
result.addToBody((BlockImpl) after);
}
return result;
}
return main;
}
protected Object renderPropertyValue(MarkupWriter writer,
String overrideBlockId, boolean
showdefault)
{
Block override = overrides.getOverrideBlock(overrideBlockId);
String datatype = model.getDataType();
if (override != null)
{
Debug.debug("overrideBlock=" + override);
Block ov = override;
return override;
}
if (showdefault)
{
[snip...]
// Don't render anything else
return false;
}
return null;
}
where formerly I'd write
<t:parameter name="lastloggedinBeforeCell">
i'm your decoration ${originalValue}
</t:parameter>
in the Component Template now I use
<t:parameter name="lastloggedinBeforeCell">
i'm your decoration
</t:parameter>
I have yet to "wrap" an Actionlink around it, I probably have to split the
ActionLink-Component into two, one before and one after the main BlockImpl,
opening and closing the Link respectively.
