    Does the "too much recursion" error come from MooTools or the nsSessionSaver.js? (Firebug right side)

    I tried with mootools-1.2.3-core.js and mootools-1.2.3.1-more.js (full options, no compression)

    --> same problem

    Firebug report "too much recursion" error from mootools :

    mootools-1.2.3-core.js (line 1112) : var result = method.apply(this, arguments);
    mootools-1.2.3.1-more.js (line 1133) : return this.get('value');

    i get the same error with FF 2.0.0.11

    too much recursion
    [Break on this error] var result = method.apply(this, arguments); mootools...3-core.js (line 1112)

    too much recursion
    [Break on this error] (1133 out of range 2) mootools...1-more.js (line 1133)

    but FF 2.0.0.20 have no problems

    • State changed from “new” to “hold”
    • Assigned user set to “Valerio”

    This is a bug in Firebug (to my knowledge), not in MooTools. Can anyone verify that this error occurs w/o Firebug installed (get something like Developer Toolbar and watch it's JS console)?

    Firefox 2.0.0.11 Firebug plugin disabled
    Firefox Error Console says:

    Error: too much recursion

    Mootools-core version:
    var MooTools = {

        'version': '1.2.3',
        'build': '4980aa0fb74d2f6eb80bcd9f5b8e1fd6fbb8f607'
    

    };

    Mootools-more version:
    MooTools.More = {

        'version': '1.2.3.1'
    

    };

    Firefox 2.0.0.1 vanilla install (no addons installed at all). Just to clear, this is not a firebug bug (tested on multiple computers and a from-scratch virtual windows install with absolutely no references to firebug).

    Using Mootools-core standalone does not produce this error.

    The function causing 'too much recursion' is on line 1114 of mootools-core (well, in the version I use), in the new Native() wrap: function, calling method.apply( this,arguments ) causes the recursion.

    This is triggered when mootools-more is loaded and an instance of URI is created (with my debug alerts surrounding it),

    alert("debug , before error, should be visible" );
    URI.base = new URI( $$('base[href]').getLast(), { base: document.location } );
    alert("debug, after error, not visible" );

    This is what actually seems to loop for ever, called when creating a new instance of URI()

    ['toString', 'valueOf'].each(function(method){

        URI.prototype[method] = function(){
                return this.get('value');
        };
    

    });

    Couldn't quite figure out why does this (the variable 'this') cause a recursion problem here.

    (trying to touch 'this' (ie. try to alert(this)) inside the function causes a stack overflow on Safari also - why this.get('value') still works as a return I do not know..)

    Hope this debug helps.

    Cheers,
    Ilkka

    And it is only the 'valueOf' prototype method that causes recursion. this.get('value') calls valueOf() internally perhaps?
