Hi,
do you implement the
interface "ColumnDecorator" ?
I guess not because the
signature of your decorate method does not match the signature of the decorate
method of the ColumnDecorator.
If you use that
interface, the object representing the current row is given as argument to the
decorate.
Check the javadocs of
that interface at: http://displaytag.sourceforge.net/11/displaytag/apidocs/index.html
regards,
Miro

Subject: [displaytag-user] uid: row object not updated?
I'm trying to build a table from an array of StartJobCard, an in-house complex class.
I use DisplayTag 1.1 and JBOSS 4.0.2.
It goes like this:
<display:table name="startJobCards" uid="currentStartJobCard">
<display:column decorator="my.package.decorator.StartJobCardDecorator" />
</display:table>
As I understand it, the uid attribute allows me to get the object in the current row, using PageContext.
So, in my decorator, I do this:
+++++
public Object decorate(Object inSJC, PageContext inPc, MediaTypeEnum
inMte) throws DecoratorException {
String result = "";
Object sjc = inPc.getAttribute("currentStartJobCard");
if (sjc != null) {
if (!(sjc instanceof StartJobCard)) {
result = sjc.toString();
} else {
result = findStatus((StartJobCard) sjc, inPc);
}
}
return result;
}
+++++
inPc.getAttribute("startJobCard") 'almost' works, in the sense that I get a StartJobCard object indeed. I was happy, until I noticed that the object wasn't actually updated, and it was the same one for every row... (i.e., the object I get is always the last one from my array of StartJobCard objects.
Am I understanding the whole 'uid' thing correctly? If not, do you see a workaround, to get current row object in my decorator?
Many thanks in advance, and I hope I've been clear enough.
