Inconsistent default value treatment for HeaderCell.group
---------------------------------------------------------
Key: DISPL-378
URL: http://jira.codehaus.org/browse/DISPL-378
Project: DisplayTag
Issue Type: Bug
Components: HTML Generation
Affects Versions: 1.1
Reporter: erwin de ley
Priority: Minor
HeaderCell.group has a default value of 0.
Case 1: For a Table containing Columns defined with the Column tag, the
HeaderCell.group values are set to -1, by the ColumnTag.addHeaderToTable()
method, snice the ColumnTag.group is -1 by default.
Case 2 : For a Table without Column definitions in the jsp, the
TableTag.describeEmptyTable() leaves the HeaderCell.group at 0.
The documentation states that the grouping requires a value > 0 in order to be
activated. So both cases above should result in no grouping.
But the TableWriterTemplate.writeTableBody() method, at line 359, checks on
value -1! So grouping is active from group==0, and the 2 cases above behave
differently!
Would be nicer if ColumnTag and HeaderCell have same default values, and
TableWriterTemplate checks correctly on the common default value...
cheers
