    <p>I've written a server-side utility that is meant to manage javascript page dependencies. During development, it serves the javascript as separate files (embeds individual script tags in the order defined), and in production mode it reads the files, minifies them (Google Closure in Whitespace only mode), and embeds them via a single script tag.</p> <p>For the moment, I've turned off minification to eliminate that variable...so all it is doing is joining the files together with a newline between each.</p> <p>When I go to production mode, I get spurious problems in a number of the files that are embedded.</p> <p>So, does anyone have any ideas of what problems I could be causing by serving a set of files as a single, concatenated file? I'm at a loss.</p> <p>For those wanting more detail:</p> <p>I am certain the order is correct.</p> <p>The list of files in question is rather large for this example, but include jquery, angular, controllers, jquery dnd fileupload, controllers, etc.</p> <p>I get "Uncaught Type Error: undefined is not a function" at this line of the combo:</p> <pre><code>(function(b){b.support.touch="ontouchend" in document;if(!b.support.touch){return;}var c=b.ui.mouse.prototype,e=c._mouseInit,a;function d(g,h){if(g.originalEvent.touches.length&gt;1){return;}g.preventDefault();var i=g.originalEvent.changedTouches[0],f=document.createEvent("MouseEvents");f.initMouseEvent(h,true,true,window,1,i.screenX,i.screenY,i.clientX,i.clientY,false,false,false,false,0,null);g.target.dispatchEvent(f);}c._touchStart=function(g){var f=this;if(a||!f._mouseCapture(g.originalEvent.changedTouches[0])){return;}a=true;f._touchMoved=false;d(g,"mouseover");d(g,"mousemove");d(g,"mousedown");};c._touchMove=function(f){if(!a){return;}this._touchMoved=true;d(f,"mousemove");};c._touchEnd=function(f){if(!a){return;}d(f,"mouseup");d(f,"mouseout");if(!this._touchMoved){d(f,"click");}a=false;};c._mouseInit=function(){var f=this;f.element.bind("touchstart",b.proxy(f,"_touchStart")).bind("touchmove",b.proxy(f,"_touchMove")).bind("touchend",b.proxy(f,"_touchEnd"));e.call(f);};})(jQuery); </code></pre> <p>which follows some other file embeds that generate global vars:</p> <pre><code>var FocusElementDirective = function() { ... } var DirectiveApplier = function(){ ... } var AgeCalculator = function(){ ... } </code></pre> <p>Another one: when I trigger an "add" event in the angular plugin for jquery fileupload, it gives Uncaught TypeError: Object # has no method 'scope'. The line it is pointing to is within the jquery fileupload angular module (line 89 of version 9.0.5):</p> <pre><code> add: function (e, data) { if (e.isDefaultPrevented()) { return false; } var scope = data.scope(), // this line </code></pre>

    1. COIs it maybe concatenating them in the wrong order? Can you identify a single problem of the many encountered and focus just on the cause of that one problem?

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).
