Todd Hansberger commented on DISPL-565:
---------------------------------------
I had the exact same problem trying to figure this out, and finally I
downloaded the source code, created my own sub-class of TotalTableDecorator,
overrided a few methods to debug them, and this is what I found:
The only time a grand total label will display is if there is a column defined
with a group = 1, so I set one of my <display:column> tags to have a group
attribute of "1" (which does not even need to be grouped). However, doing that
not only showed the total label, but it also added subtotal rows for my grouped
column, which I didn't want.
In order to remove the subtotal rows, I sub-classed TotalTableDecorator like so:
<code>
public class GrandTotalOnlyDecorator extends TotalTableDecorator
{
public GrandTotalOnlyDecorator()
{
super.setTotalLabel("Total"); // set this to whatever you want, it
defaults to "Total"
}
protected String createTotalRow(boolean grandTotal)
{
if(grandTotal)
{
return super.createTotalRow(grandTotal);
}
return "";
}
}
</code>
Then in the <display:table> tag, set the decorator attribute to the full
class name of your sub-class above. I sure hope there is an easier way to do
this.

> org.displaytag.decorator.TotalTableDecorator totals = new
> org.displaytag.decorator.TotalTableDecorator();
> totals.setTotalLabel("Full Total");
> pageContext.setAttribute("totals", totals);
> </jsp:scriptlet>
> and then added decorator="totals" to my table, but only the value is shown,
> not the label.
> Thank you!
