    <p>Hey, I got the problem. The thing is this library isn't expecting you to use multiple animations at a time. the function SKEL.EFFECTS.Slide.animate which inits the animations creates a field in the animated object, called skel_animate_id, which is in fact the id of a timer set up to do the animation. </p> <p>As this library doesn't expect multiple animations at a time, when you create a new animation, it just does <code>element.skel_animate_id = setInterval(.....</code>, and if you are following me, you'll realize that anything that was on <code>skel_aimate_id</code> before (i.e. the library's only reference to any previous animation's timers) is lost after that assignment.</p> <p>Now, there's a step function, called by the timers, which is in charge of recognizing when the animation has ended, and stop the timer itself, but it does that by calling <code>clearInterval(element.skel_animate_id);</code>, which will obviously only clear the timer related to the last attribute animated.</p> <p>Long story short, when you call the second attribute's animation (before the first one ended), you leave an open timer, which keeps on going and going "animating" the first attribute (i.e. setting it to it's final value).</p> <p><strong>EDIT:</strong> <a href="http://jsfiddle.net/FcFzc/" rel="nofollow">Live demo of fix.</a></p> <p><strong>THE GUILTY SNIPPET</strong></p> <p>Lines [488-531]</p> <pre><code>SKEL.EFFECTS.Slide = { counter: 0, fps: 50, //handles the animation from an attribute to an attribute animate: function(element,cssAttribute,from,to,duration,transition){ if(element.css('display') != 'block'){ element.skel_old_display = element.css('display'); } //if there isn't a default transition set one if(!transition){ transition = SKEL.Transitions.quadOut; } //cancel any current animation // FELIX Note: I've commented this because when we had 3 transitions on the same element, this function would make only the first one to work. //SKEL.EFFECTS.Slide.stop(element); var startTime = new Date().getTime(); //IE doesn't support arguments, so make a function that explicitly calls with those arguments element.skel_animate_id = setInterval(function(){ SKEL.EFFECTS.Slide.step(element,cssAttribute,from,to,duration,startTime,transition); },(1000/SKEL.EFFECTS.Slide.fps)); return element.skel_animate_id; }, //cancels any animation event stop: function(element){ //console.log(this,element,element.skel_animate_id); //console.log(element.skel_animate_id); if(element.skel_animate_id){ clearInterval(element.skel_animate_id); element.skel_animate_id = 0; if(element.skel_old_display){ element.css('display',element.skel_old_display); } } }, </code></pre> <p><strong>POSSIBLE SOLUTION</strong></p> <p>I'd have <code>skel_animate_ids</code> as an array, and store every interval with a reference to the attribute animated, so the step function nows which interval to clear.</p> <p>in SKEL.EFFECTS.Slide.animate</p> <pre><code>if (!element.skel_animate_ids){ element.skel_animate_ids = new Object(); } //IE doesn't support arguments, so make a function that explicitly calls with those arguments element.skel_animate_ids[cssAttribute] = setInterval(function(){ SKEL.EFFECTS.Slide.step(element,cssAttribute,from,to,duration,startTime,transition); },(1000/SKEL.EFFECTS.Slide.fps)); return element.skel_animate_ids[cssAttribute]; </code></pre> <p>then in SKEL.EFFECTS.Slide.stop</p> <pre><code>//cancels any animation event stop: function(element,attribute){ if(element.skel_animate_ids[attribute]){ clearInterval(element.skel_animate_ids[attribute]); delete element.skel_animate_ids[attribute]; if(element.skel_old_display){ element.css('display',element.skel_old_display); } } }, </code></pre> <p>and in SKEL.EFFECTS.Slide.step (line 575)</p> <pre><code>if(finished){ SKEL.EFFECTS.Slide.stop(element,cssAttribute); } </code></pre> <p>I think that should do it, but I can't really test it in my browser. If my code doesn't quite work, I must have missed something, but I'm still sure that's the problem, you just have to figure out how to solve it (or change libraries =D). You just try my suggestion, let me know how it worked.</p> <p>Cheers</p> <p><strong>EDIT:</strong> I couldn't wait, so I whipped a JSFiddle to test, and yeah, it works with those changes. <a href="http://jsfiddle.net/FcFzc/" rel="nofollow">Check it out</a>.</p> <p><strong>EDIT2:</strong> Corrected typo: was still referencing skel_animate_id instead of skel_animate_ids in the first bit of code.</p>

    1. COWow, that was very neat! Now i understand where i was doing wrong, yeah, it makes total sense. I'm gonna test this when i get to work, and really thanks for pointing all that explanation.

    2. CO@Tio Hey, I had an error in the code for the proposed solution. Already fixed it in my answer: you should always be working with skel_animate_ids now instead of skel_animate_id (I had left one skel_animate_id in the first bit of code).

    3. COi noticed that, don't worry. :) Already fixed on my code. Thank you very much for this solution, bro. I wish someday i'll be able to know as much as you guys here, so i could help other people too. Marked as best answer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
