Description

Hello,
I have been using display tag with column decorators in my project, recently there was case where we have to use the value in session to decide on the decoration of a column, As column decorator isn't supporting PageContext as of v1.0, i switched to Table decorator,everything works fine except sorting of Date Object Columns. The same column sorting is working fine with "Column Decorator". Date based sorting is very important in the existing functionality and i would request you to kindly help me with this issue. Please find the code snippet attached.

Hello,

I managed to solve this one with some work-aound. There is a condition in the compare method of RowSorter class, this logic checks for the decorator and the getterMethod of the property. If a getterMethod is found for the property it uses the decorated value for sorting and not the underlying object. In my case the underlying object was java.util.Date ,but it was always sorting based on the decorated value instead of the object.

Please find my work-around for this problem.
Added a new dummy Property with attribute sortProperty=originalProperty and added a getterMethod for the dummyProperty in my decorator class. Please find the attached file work-around.txt.

Can we have an attribute something like "sortByObject=true" in future release, so that we need not have to do any work around and decide the sorting pattern at the tag level.

public String getYourDateSortable() {
return String.valueOf(yourDate.getTime());
}

should be a work-around - see also http://stevelibonati.wordpress.com/2008/08/26/display-tag-date-column-sorting/

For decoration use property="decoratedProperty".
For ordering use sortProperty="property".
