> Key: TAPESTRY-669
> URL: http://issues.apache.org/jira/browse/TAPESTRY-669
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Environment: Windows XP, Internet Explorer 6
> Reporter: Herbert Hui
> Assignee: Howard M. Lewis Ship
> Priority: Minor
>
> Line 781 in DatePicker.js fails when thirdparty methods are added to Array
> using Prototype.js from http://prototype.conio.net/
> For example if you add the flatten method from
> http://www.schuerig.de/michael/javascript/stdext.js
> then line 781 will attempt to execute the
> "frm.replace(/\bflatten\b/,'function(excludeUndefined) {return
> Array.flatten(this, excludeUndefined);}');"
> Suggested modification to DatePicker.js:
> var keys = new
> Array('d','dd','ddd','dddd','M','MM','MMM','MMMM','yyyy','yy');
> for (var i = 0; i < keys.length; i++) {
> frm = eval("frm.replace(/\\b" + keys[i] + "\\b/,'" + bits[keys[i]] +
> "');");
> }

> Array.flatten = function(array, excludeUndefined) {
> if (excludeUndefined === undefined) {
> excludeUndefined = false;
> }
> var result = [];
> var len = array.length;
> for (var i = 0; i < len; i++) {
> var el = array[i];
> if (el instanceof Array) {
> var flat = el.flatten(excludeUndefined);
> result = result.concat(flat);
> } else if (!excludeUndefined || el != undefined) {
> result.push(el);
