I think it might be the last one, but we really need Johnathan's input, because I don't think anyone knows how it works.

Johnathan..?

Oh and meant to ask you Nikodem,

Do you have any plans to do the Scenario connector? Is that the last outstanding page type Julian - it's on my list (but really low on my priorities) but would be nice to draw a line under them...

Also I'd appreciate any feedback on the rendering of the Javascript engine in IE6/7/8/9/10 since my R1028 changes, or even just to test it on some more examples - you can use BrowserStack.com for any browsers that you don't have access to...

Subject: [Xerte-dev] Possible Issue (maybe) with Xenith.js
Importance: High

Hi (this is probably for Nikodem),

I saw a console error in xenith.js yesterday when debugging a video issue from the Forum that I can't seem to reproduce (and can't even remember which browser it was in, perhaps a Mac or Linux on...) but it might be worth keeping an eye out for if you are developing any of the javascript engine...

>From memory, this code appeared to be the culprit (but as I say it's not doing it in Chrome or Firefox now after recent trunk updates) - Lines 145-160 R1031

                        if (x_pages.length < 2) {
                                // don't show navigation options if there's only one page
                                $("#x_footerBlock .x_floatRight").remove();

                        } else {
                                if (x_params.navigation == undefined) {
                                        x_params.navigation = "Linear";
                                }
                                if (x_params.navigation != "Linear" && x_params.navigation != "Historic" && x_params.navigation != undefined) { // 1st page is menu
                                        x_pages.splice(0, 0, "menu");
                                        var page = new Object();
                                        page.type = "menu";
                                        page.built = false;
                                        x_pageInfo.splice(0, 0, page);
                                }
                        }

Basically Fay added this code in to hide the navigation when there is only one page. However, it seems to me anyway that, when there's more than 1 template page the page object is created and page.type and page.built are set... these are then used later on... but they give an undefined console error when there is only one page as page hasn't been defined...

This is the last thing on my list before getting back to working on the API and making a proper start on the HTML5 editor so would appreciate it if you had time to take a quick look and see if you can reproduce and fix...

PS, Fay probably passed on the google doc bug/features sheets to you before she left. If you are planning to keep them relatively up to date with the Javascript engine developments then I will usually dip in there when I need a welcome break from PHP and give you a hand... alternatively if want a fresh pair of eyes casting over any code then just drop me an email on or off list...
