Hello everybody,
I'm quite new to Wicket, and to web component framework to.
Until now I just try simple examples, which seem to work (really) fine.
So now, I want to pass to a little more complexe one, to try to
understand how things work in Wicket (version 1.3).
I work on LDAP directories, so I play with *entries*, identified by
there "dn". Each entry has a Set of *attributes*. Attributes are linked
to an unique entry, are identified by there "name", and have a Set of
*values*. A spring managed DAO allows to do CRUD actions on entries. A
summary of these object is given at the end of the email.
I think I understand that I have to take care that objects are
detachable. I succeed in using spring annotation to use a spring proxy
to connect to my DAO and retrieve an entry and write his it on screen.
Now, I want to see how powerful is wicket, and for that I want to
translate this algo to edit an entry
* given an entry {
print the dn ;
for each attribute {
select an input method base on the name of the attribute;
for each value {
add an edit box according to the input method;
}
}
}
(I think that the printing of an entry would work on the same model,
say :
* given an entry {
print the dn ;
for each attribute {
select a formatting method;
for each value {
print the value formatted according to the selected method;
}
}
}
)
If I well understand how works wicket, I need to define a detachable
model for the "entry" object, and a detachable model for each "type" of
attribute. Then, I have to play with repeaters at attribute and value
level. Or perhaps I need to define a component for each attribute ?
Well, as you see, I don't know where to begin. I look carefully in
examples and wiki, but I don't really find how to put concept together.
Could you, please, point me some entries or give me some advice in the
main line of what I have to do to implement my algo ?
Any help would be welcome,
Francois
-----------------------------------------
PS : to detail a little bit mare, I have these objects (and I have to
deals with them, I cannot change them because I relay upon a framework):
SpringEntryDao {
Entry get(String dn);
...
}
Entry {
String dn:
Set<Attribute> attributes;
Attribute getAttribute(String name)
void setAttribute(Attribute attribute)
...
}
Attribute {
String name;
Set<Value> values;
Value getValue(); //return next value if one remain, null otherwise
Set<Value> getValues(); //return a set of all value
...
}
Value {
Object value;
Object getValue();
...
}
