Hi Bob,
That makes a lot of sense. Many of our objects cannot be instantiated
without arguments to the Constructors, so I've made sure that all of
them were set up previously and that the Form.copyTo wouldn't come
across anything null.
Here is some more info. Click calls the getter method of the path to
figure out whether to instantiate
a new instance or not.
field = new TextField("address.street");
form.copyTo(client);
From the above Click will tokenize the field path into "address" and
"street". Next it will try and check if
address is null through reflection by invoking the address getter:
client.getAddress();
If client.getAddress returns null Click tries and instantiates the Address.
If you use a debugger you can place a breakpoint roughly on line 595 of
class net.sf.click.util.ContainerUtils#ensureObjectPathNotNull.
If your breakpoint is hit, it means Click tries to instantiate a object...
kind regards
bob
