Body
It isn't perfect, but I found a partial solution. Fact 1: <code>Error.prototype</code> is an Error object. Fact 2: The method <code>Error.prototype.toString</code> is called whenever an error is created. Fact 3: The field <code>Error.prototype.toString</code> can be modified. That method typically just returns the string "Error", so we can replace it with our own method that stores the stack and then returns the string "Error". <pre class="lang-js prettyprint-override"><code>Error.prototype.toString = function() { if (typeof this.stack === "undefined" || this.stack === null) { this.stack = "placeholder"; // The previous line is needed because the next line may indirectly call this method. this.stack = $.stack; } return "Error"; } try { throw new Error("Houston, we have a problem."); } catch (e) { $.writeln("Line: " + e.line); $.writeln("File: " + e.fileName); $.writeln("Message: " + e.message); $.writeln("Stack: " + e.stack); } </code></pre> Result: <pre><code>Line: 11 File: ~/Desktop/Source10.jsx Message: Houston, we have a problem. Stack: [Source10.jsx] toString() </code></pre> It works! The only problem is automatic errors. <pre class="lang-js prettyprint-override"><code>Error.prototype.toString = function() { if (typeof this.stack === "undefined" || this.stack === null) { this.stack = "placeholder"; // The previous line is needed because the next line may indirectly call this method. this.stack = $.stack; } return "Error"; } try { var foo = null; foo.bar; } catch (e) { $.writeln("Line: " + e.line); $.writeln("File: " + e.fileName); $.writeln("Message: " + e.message); $.writeln("Stack: " + e.stack); } </code></pre> Result: <pre><code>Line: 12 File: ~/Desktop/Source12.jsx Message: null is not an object Stack: undefined </code></pre> So it doesn't work on all errors, but its progress.

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.
