Access to the current row in a column decorator
-----------------------------------------------
Key: DISPL-392
URL: http://jira.codehaus.org/browse/DISPL-392
Project: DisplayTag
Issue Type: New Feature
Components: Decorators
Affects Versions: 1.1
Reporter: Hani Suleiman
Fix For: 1.1.1
Attachments: patch.txt, RowAwareColumnDecorator.java
Currently it is not possible to get access to the current row within a column
decorator. Ideally, the API would be changed to pass this in, so a decorator
has access to more contexual information for cases where it needs to show
multiple links and so on within one cell.
However, for the sake of backward compatibility, the API cannot be changed. My
solution is to create a new class RowAwareColumnDecorator that's an abstract
implementation of DisplaytagColumnDecorator, with a get/setRowObject accessor.
The next change is Column.java, to check for this subclass, and if so, set the
row object before calling decorate.
Patch attached.
