Thanks very much for your help Jeff. There were a few issues with the code
you've sent, which I've fixed. I've included the modified code below for the
benefit of any future readers. Please let me know if you can see any problems
with this implementation
public class SuppressZeroDecorator implements DisplaytagColumnDecorator {
public Object decorate(Object rowObject, PageContext pageContext,
MediaTypeEnum mediaType) {
if (rowObject != null && rowObject.toString().trim().equals("0")) {
return null;
}
return rowObject;
}
}

Subject: Re: [displaytag-user] suppress zero values
You should probably ColumnDecorator since you want to use it in several places.
Here is an example of how to do that.
// in the jsp
<display:column property="dataAvailable" title="Has Data"
decorator="com.microsoft.BooleanColumnDecorator" />
// in the decorator ZeroColumnDecorator
public class ZeroColumnDecorator implements DisplaytagColumnDecorator
{
/**
* retrieve the html decorate string
*/
public String decorate(Object rowObject, PageContext pageContext,
MediaTypeEnum media)
{
String display = "";
if (rowObject instanceof Integer)
{
Integer value= (Integer)rowObject;
// build the html
display=(value.intValue()>0)?value:"";
}
return display;
}
}

Hi,
I would like to prevent zero values from being displayed in a HTML table that I
generate with displaytag. It seems like implementing a decorator would be the
most convenient way to achieve this, but I'm not sure whether I should be
exending TableDecorator or PageDecorator?
If someone could let me know which of these 2 is the most appropriate, and give
me some pointers regarding which methods to override, it would be much
appreciated. I would like to be able to use this decorator in any table, i.e.
the decorator should not depend on the table retrieving it's data from beans of
a particular class
Thanks in advance,
Don
