Sorting on the Date Format Treating it as Date and not as String for the table Component

[Amol Yadwadkar <ay...@webifyservices.com>]

Hi All/MB,
I am using Table Component.I have the following Issue:-
I am having one Column which shall accept Date in the Format as "Aug 21, 2003 10:37am PST" and I will like to sort in this Format from Table Component.
Is it Possible ?

Problems that I am facing:-
1>> Date type object does not give me the facility to convert it into the Format as "Aug 21, 2003 10:37am PST" (same Date Object) it will be the String 
(I mean "Aug 21, 2003 10:37am PST " will be treatted as String) and Sorting will happen for the String and not for the Date which is required.

Please let me know if I am not clear with my Problem to u all
Thankx
best regds,

Hi Amol,

If I understand you correctly you want to present date value in your custom
date format but you want it to be sorted as a date object. So here is my
solution:

Extend class SimpleTableColumn and override the following methods:

    /**
      * this method will return the string presentation of date in your data
format
      */
  public IRender getValueRenderer(IRequestCycle arg0, ITableModelSource
arg1, Object arg2);

    /**
      * This method will return the real date object - java.util.Date
      */
  public Object getColumnValue(Object arg0);

The default column comparator uses the second method to obtain a columnValue
for each row. That will be a Date object that implements Comparable
interface so they will be compared as a date objects(not as a string
presentation).
