[twdev] [TW5] compiled filter with titles doesn't work? but with tags it does... Help please

[Felix Küppers]

Hi,

I have worked a lot with compiled filters now but this one here... I just 
don't get it.

If you open tiddlywiki.com and a firebug (or similar) browser-console and 
enter

var filter = "[title[Get the Ring]] [title[Kill the Dragon]]";

var compiledFilter = $tw.wiki.compileFilter(filter);

var changedTiddlers = { "Get the Ring": {"modified": true} };

var source = function(iterator) {
  $tw.utils.each(changedTiddlers, function(property, title) {
    var tiddler = $tw.wiki.getTiddler(title);
    console.log(title);
    iterator(tiddler, title);
  });    
};

var results = compiledFilter.call($tw.wiki, source);
console.log(results);
// outputs ["Get the Ring", "Kill the Dragon"]



Why doesn't it only display "Get the Ring"?


In fact, the compiled filter call does not even call the source function.

Consider this

var filter = "[title[Get the Ring]] [title[Kill the Dragon]]";

var compiledFilter = $tw.wiki.compileFilter(filter);

var changedTiddlers = { "Get the Ring": {"modified": true} };

var source = function(iterator) {
  console.log("hello woooooorld");
};

var results = compiledFilter.call($tw.wiki, source);
console.log(results);

// outputs ["Get the Ring", "Kill the Dragon"]



But the filter is valid, if you enter it in tiddlywiki.com advanced search 
it will find the tiddlers

An example that works perfectly but the filter is different:

var compiledFilter = $tw.wiki.compileFilter("[tag[task]]");

var changedTiddlers = { "Get the Ring": {"modified": true}, "bla": {
"modified": true} };

var source = function(iterator) {
  $tw.utils.each(changedTiddlers, function(property, title) {
    var tiddler = $tw.wiki.getTiddler(title);
    console.log(title);
    iterator(tiddler, title);
  });   
};

var results = compiledFilter.call($tw.wiki, source);

console.log(results);
// = [ "Get the Ring" ]

Where is my mistake?

Thanks
Felix
