Edited Issue: Access of undefined array in MaskedEditBehavior [27921]

There is a bug in Sys.Extended.UI.MaskedEditBehavior.prototype.ConvFmtTime, where an undefined Array is accessed. It can easily be seen, when looking at the source:

```
ConvFmtDate: function(input, loadFirst) {
var m_arrDateLD,
m_arrDate;

m_arrDate = input.split(this.get_CultureDatePlaceholder()).filter(function(element) {
return element != "";
});
m_arrDate = m_arrDate.map(function(element) {
return element.replace(/[^\/\d]/g, '')
});

if(loadFirst) {
if(this.get_UserDateFormat() != Sys.Extended.UI.MaskedEditUserDateFormat.None) {
[...]

m_arrDate[this.get_CultureDateFormat().indexOf("D")] = m_arrDateLD[this._CultureDateFormat.indexOf("D")];
m_arrDate[this.get_CultureDateFormat().indexOf("M")] = m_arrDateLD[this._CultureDateFormat.indexOf("M")];
m_arrDate[this.get_CultureDateFormat().indexOf("Y")] = m_arrDateLD[this._CultureDateFormat.indexOf("Y")];
}
}
[...]
```
the Array "m_arrDateLD" is never defined, but when "loadFirst" is true, its values are read.
This JS-error only happens when the page is loaded (loadFirst) but it causes all following scripts to fail, which makes this component of the Toolkit de facto unusable
