of function: setProperty: function(attribute, value)

    Aicke: Could you please provide an example? Unfortunately there isn't enough information here to work with.

    as a test I executed only:

    window.addEvent('domready', function() {
    $$('a')[0].set('text', 'test'); $$('div')[0].set('text', 'test'); });

    this results in 2 syntax errors in the mentioned line above, with Companion.JS (a free javascript debug plugin for IE) in IE6 (the Xenocode version to get it running beside IE8). Can't check it with real IE6.

    I set up a very simple test page and couldn't reproduce your error.

    • State changed from “new” to “invalid”

    I cannot duplicate the error either. I will close until a better example is given. This could be the result of a problem elsewhere.

    I have the same problem using MooFlow on IE6 (under SharePoint). I believe it could be linked to the fact my page has no DocType, and hence works on quirks mode.

    Here's the line in MooFlow code that triggers the error :
    this.loader.set('text', (counter + 1) + ' / ' + this.loadedImages.length);

    Actually "this.loader.set('text', 'anything');" triggers the error too...

    I had this problem also, so I long time used Element.set('html',xxx) instead of Element.set('text', xxxx).
    I used IE6 and IE8 installed together.
    Problem now dissapeared after unistaling IE8 from computer.

    I am using MooTools 1.2.3 and can also confirm this issue. (IE throws "Unknown Runtime Error")

    Appears to be isolated to IE6 and is failing on both set('text') and set('html').

    @tvx, I also have IE8 installed, but unfortunately cannot uninstall it to test if the problem also went away. However, I tested on a colleague's computer w/ Windows XP native IE6 (never had IE8 installed) and the problem persisted.

    NOTE: I am running IE6 via "Internet Explorer Collection" from:

    I found that both .set('text','whatever') or .set({text:'whatever'}) both cause the error in IE6 consistently.I had to go through all of the scripts I wrote for a client using set('html' instead and it worked fine after that.

    It's interesting that pixelchutes say's

    Appears to be isolated to IE6 and is failing on both set('text') and set('html'). for me using 'html' worked in IE6

    I should not that all the elements I was working with were created via new Element not accessed from the existing dom incase that makes a difference (you never know with IE)

    If its an unfixable issue for ie6 perhaps 'text' could be turned into an alias for 'html' in the set function if mootools has detected the browser to be IE6?
