Hi,

The ORM we are using accepts and returns custom data transfer objects
(GenericDTO). This generic dto is implemented as a hashMap of pojo's (by pojo I
mean a java class with getter and setter methods))
For example,
public class GenericDTO implements Serializable {
private static final long serialVersionUID = 1L;
private Map<String, Attribute> attributes = null;
private String name = null;
public GenericDTO(String name) {
notNull(name, "The name of the DTO cannot be null...");
this.attributes = new HashMap<String, Attribute>();
this.name = name;
}
public GenericDTO add(String name, Attribute attribute) {
notNull(name, "Attribute name cannot be null");
notNull(attribute, "Attribute with name: " + name + " is null!");
this.attributes.put(name, attribute);
return this;
}
// there are getter/setter method to return the HashMap of Attributes.
The attribute class is the base class of all data types. So we have
StringType (for String), IntegerType (for Integer) that extend Attribute. Class
Attribute
public Object getInputValue();
public void setInputValue(final Object object);
ZK supports java EL expressions so it is possible for me to bind this generic
dto with zk ui controls as follows
<label value="@load(each.attributes.account.inputValue)" /><label
value="@load(each.attributes.fullName.inputValue)" /> Where "each" represents
the generic dto, attributes (is a hash map with key as field name and
inputValue holds the field value).
I am assuming it is possible to create ActionScript (as3) versions of
GenericDTO, Attribute (with subclasses StringType, IntegerType e.t.c)
1. Can I bind my custom DTO to royale ui controls ? would the above be
possible ? 2. Can BlazeDS support transfer of such objects from a royale
client to my java back end ? 3. I am currently using the mvvm approach with
ZK. is mvvm design pattern supported with royale ? 4. Are command (method
bindings) supported ? can i bind a button click to an as3 method ?
Roman,
