Paul,
I would love for us to start getting a good body of these decorators in
the code base. Is this what you were looking for?
Hope this helps,
Benjamin Simpson
Package my.definition.decorators;
Import my.definition.of.Address;
Public class AddressColumnDecorator implements ColumnDecorator {
Public String decorate(Object obj) throws DecoratorException {
If(object == null || obj instanceof Address == false)
return ""; // throw new DecoratorException("Class cast or null, you
choose" + obj);
Address address = (Address) obj;
Return new StringBuffer(256)
.append(address.getStreet())
.append("<br>")
.append(address.getCity())
.append(", ")
.append(address.getState())
.append(' ')
.append(address.getZip())
.toString();
}
}
<display:column property="homeAddressObj"
decorator="my.definition.decorators.AddressColumnDecorator" />

Subject: RE: [displaytag-devel] ColumnDecorator
Since the addition of the implicit row object in 1.0-b1 I've replaced
all my
ColumnDecorators with code in the body of the <column>tag. I think this
is a
far nicer approach - I can create a custom tag to do any custom
formatting &
re-use the tag anywhere - not just inside a <table>.
You can use this approach to solve the problem you mention with the
jstl:
<display:column sort="true">
<fmt:formatDate value="${current.dateLogged}" type="date"
dateStyle="SHORT" timeStyle="SHORT"/>
</display:column>
Does anyone have any examples of formatting that can be done with a
column
decorator, but not via column body?
Paul

Subject: [displaytag-devel] ColumnDecorator
One use of the ColumnDecorator (a good addition) is to format dates
correctly according to the locale of the user. In order for the locale
information to be available to the decorator, a reference to the request
object needs to be available, correct? Would it make sense to extend the
ColumnDecorator class with a method for passing a reference to the
request object? This could be called once at class initialization.
Comments?
