Passing more than one property to columntag

In one of mine ColumnDecorator classes I need more than one property to handle the decoration of the column.
As I understand the <display:column property="methodname" .....decorator="some.decorator.class"/> grabs the methodName, uses the Reflection api to actually grab the value from the method and passes it on to the decorator class for the final finish / appearance. Formatting a Date Object is quite easy, as shown in one of the examples submitted with the displaytag distribution and I have made severals myself, including displaying an image.
My requirements however is this: One column should display some text, along with an image.
Piece of code from a table before using displaytag:
...
<td>
<bean:write name="element" property="name" />
<il:productViewer name="element" property="type" />
</td>
...
Meaning, within the <td></td> tag I write the name, then by using a taglib and passing in the 'type' property I am returning html code for displaying the proper image. Both name and image is displayed within one 'column' How to solve this with the <display:column> tag?
I need both the name and image within 1 column (as within <td></td>) not like this:
<display:column property="name" ..../>
<display:column property="imageName" ... decorator="some.image.decorator.class/>
Actually I would like to pass in the object beeing iterated to some attribute in the columntag.
Anyone with some good ideas?
Consider this as closed. I added a method in the DTO object returning itself.
SomeDTOObject {
.
.
.
public SomeDTOObject getSelf() {
return this;
}
}
<display:table .....>
<display:column property="self">
</display:table>
Allowing me to do more computations inside a ColumnDecorater since I now can retrieve all values from the SomeDTOObject, rather than a simple value from the same object.
