One way to achieve this is the override the transclusion method so
that instead of displaying nothing it displays a msg of your choice.
I have written a short plugin that achieves this.
(function(){
var macro = config.macros.tiddler;
var _transclude = macro.transclude;
macro.transclude = function(wrapper, tiddlerName, args){
// check to see if empty
var text = store.getTiddlerText(tiddlerName);
if(!text){
config.macros.tiddler.renderText(wrapper,tiddlerName+"
does not
exist",tiddlerName,params);
} else {
// call original
_transclude(wrapper, tiddlerName, args);
}
};
})();
You can change 'tiddlerName+" does not exist"' to any msg you want to
display.
Hope that is what you were looking for...
