Column sorting is broken with a decorator
-----------------------------------------
Key: DISPL-501
URL: http://jira.codehaus.org/browse/DISPL-501
Project: DisplayTag
Issue Type: Bug
Components: Paging/Sorting
Affects Versions: 1.1.1
Reporter: allan flatoff
I created a column called "Document Title". I created a Table Decorator so I
could wrap a URL around the data (since the current linking implementation does
not support target="" in the hyperlink).
Example Decorator:
public String getDocumentTitle() {
Row currentRow = (Row)getCurrentRowObject();
String pidString = currentRow.getPidString();
String documentTitle = currentRow.getDocumentTitle();
return "<a href=\"/BPView/docOpener.jsp?pid=" + pidString + "\"
target=\"_blank\" class=\"doclinks\"><nobr>" + documentTitle + "</nobr></a>";
}
After doing this, the column no longer sorted on the data that was in my
"documentTitle" property, instead it sorted on the TEXT that was put into the
documentTitle after the decorator had been applied - so effectively I was
sorting on "pidString" instead.
Note that in the current URL linking mechanism, applying a URL does not alter
the Sorting. It still sorts on the data from the column instead of the URL
that was wrapped around the hyperlink.
Similarly, adding a decoration to a column should not have an effect on the
sort. Perhaps there could be an optional parameter sortOnDecoratedColumn or
something which would allow you to specify to sort on the actual data or the
"decorated data" for the column.
