DatePicker.js line 781 javascript error when Array is customized using
Prototype.js from http://prototype.conio.net/

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
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);
}
}
return result;
};
if (!Array.prototype.flatten) {
Array.prototype.flatten = function(excludeUndefined) {
return Array.flatten(this, excludeUndefined);
}
}
