Niall,
Your response got me headed in the right decision. I have already written
my own iteration scheme that rolls through a returned RowSet. As such, I
went ahead and wrote a tag that would return a class attribute the will
rotate through class values. Example:
<tr <afrs:RotateClass id="caseTableClasses" classes="dataViewOdd
dataViewEven"/> >
where
id attribute: uniquely identifies this set of class values to rotate through
for this page (scoped within the pageContext)
classes attribute: provides a space delimited list of class values to rotate
through. Note that even though my examples shows only two class items,
there could be any number.
The example above would yeild:
<tr class="dataViewOdd "> on the first time through, and
<tr class="dataViewEven "> on the second time through
The tag is not dependant on any iteration sheme other than it expects to be
used within the scope of some type of iteration. The tag also assumes that
the classes identified in the 'classes' attribute have been set up in a
style sheet or style tag.
If anyone thinks this would be generically useful, I'd be glad to contribute
it to the taglibs project. If it appears to be redundant effort, I won't
bother.
Thanks for the response,
Bill Pfeiffer
