Hi,
I have a column in a table that is mapped to a collection. I want this
column to display a number of items in this collection, so I'm using a
decorator for this column that returns the collection size.
While it displays what is needed, when I'm trying to sort this column it
gives some unpredictable and inconsistent results. Perhaps it's just not the
best way to accomplish what I want or there is something I'm doing wrong.
Anyway any halp would be appreciated.
Here is the code:
in my jsp:
...
<display:column property="items" title="${itemsTitle}" sortable='true'
decorator="com.util.ItemsNumberFieldDecorator"/>
...
decorator:
public Object decorate(Object object, PageContext pageContext,
MediaTypeEnum mediaTypeEnum) throws DecoratorException {
Collection itemsCollection;
try {
itemsCollection = (Collection)object;
} catch (ClassCastException e) {
return 0;
}
if(itemsCollection != null){
return itemsCollection.size();
}
return 0;
}
