Description

I have a table that uses nested properties in the columns:

<display:table name="customers" decorator="CustomerTableDecorator" id="customer">
  <display:column property="address.postalCode"/>
</display:table>

I want to decorate the column with a TableDecorator, but I cannot specify that the property "postalCode" should be decorated, as the hasGetterFor method of Decorator considers only the "address" part of the property name. Is there a way to do this or would this be an enhancement?

It should work, if you add to your table decorator a getAddress() method. The getPostalCode() method will be called on the object returned by the decorator. Better, you could add a getAddressPostalCode() (or similar) methods to your table decorator directly.

testcase added for nested properties.
using <display:column property="address.postalCode"/> will cause the getAddress() method to be called on your decorator, and getPostalCode() will be called on the returned object, as expected.

If you want to change/decorate the value returned by getPostalCode() you could add a new method to the table decorator, for example:

public String getAddressPostalCode() {
    return (Something)getCurrentRowObject()).getAddress().getPostalCode() + " - decoration";
}
