Subject: Re: LazyActionForm
I have submitted LazyDynaBean and LazyDynaClass to commons beanutils.
http://issues.apache.org/bugzilla/show_bug.cgi?id=29879
The version of LazyDynaBean posted on my web site only dealt with "simple"
properties, but the version submitted to commons now handles mapped and
indexed properties in a "Lazy" way.
Setting a 'mapped' property now adds the mapped property and instantiates a
Map if it doesn't exist.
Setting an 'indexed' property now adds a List property and instantiates a
List if it doesn't exist. Also automatically grows Lists or Arrays if they
are not big enough to accomodate the index being set.

This is a blank Struts configuration file with an example

Tiles and the Struts Validator are configured using the factory defaults
and are ready-to-use.
NOTE: If you have a generator tool to create the corresponding Java classes
for you, you could include the details in the "form-bean" declarations.
Otherwise, you would only define the "form-bean" element itself, with the

This plugin initialize Tiles definition factory. This later can takes some
parameters explained here after. The plugin first read parameters from web.xml, then
overload them with parameters defined here. All parameters are optional.
The plugin should be declared in each struts-config file.
- definitions-config: (optional)
Specify configuration file names. There can be several comma
separated file names (default: ?? )
- moduleAware: (optional - struts1.1)
Specify if the Tiles definition factory is module aware. If true (default),
there will be one factory for each Struts module.
If false, there will be one common factory for all module. In this later case,
it is still needed to declare one plugin per module. The factory will be
initialized with parameters found in the first initialized plugin (generally the
one associated with the default module).
true : One factory per module. (default)
false : one single shared factory for all modules
- definitions-parser-validate: (optional)
Specify if xml parser should validate the Tiles configuration file.
true : validate. DTD should be specified in file header. (default)
false : no validation
Paths found in Tiles definitions are relative to the main context.
