Re: Chart and Graphs with Legend
You may check out GWT-RCharts hosted on http://code.google.com/p/gwt-rcharts/ and demo at http://gwt-rcharts.appspot.com/ .

Re: GWT Chart which displays bars on x axis at irregular intervals
You may check out GWT-RCharts hosted on http://code.google.com/p/gwt-rcharts/ and demo at http://gwt-rcharts.appspot.com/ . You can trick API to give irregular interval at categorical axis on CategoryDataTable by giving space instead of name like jan,feb, ,apr, , ,july,.. just take care you give different amount of space each time.

Re: RequestFactroy dilemma when entity id is null.

RequestFactroy dilemma when entity id is null.
Hi everyone,
I have been using GWT-RequestFactory and I have to admit that it pretty
much ease and speed up the development but also some times I feel a bit
more control and flexibility required to be given out of the *API* to
developer.
In short my problem here is : I am not able to send an entity proxy to
server with an id and null version because I get something like this
*The persisted entity with id '1' has null version'*
Here is detailed explanation by example
1)Consider Entity : Employee (id, name, age, address, city country,
gender).
2)Consider a search by keywords page where we have textboxes for
i) Employee ID
II) Name
iii) City
iv) Country
v) gender
3) User chooses any number of above fields, types things and hit enter.
eg. Name : thom --- hit on search
4) A Celltable or Grid appears as results of search
eg. list of all employees whose name like '%thom%', - Thomas, Thor etc
Hope that explains the feature. So here I am sending the keywords to sever
wrapped in a bean proxy itself. for example when user hits 'Search' button
: -
req = reqFactory.getEmployeeRequest();
EmployeeProxy emp = req.create(EmployeeProxy.class);
emp.setId(idTextBox.getValue()); //getting entered (or null) value in
text box
emp.setName(nameTextBox.getValue());
//..
req.searchEmployeeByKey(emp).fire(new ReceiverListEmployeeProxy ()
{
public void onSuccess(ListEmployeeProxy list) {}
});
Here I am using a entity proxy just for search purpose. But if the '*id'
*entity
is populate ( consider user knows employee id and enters it in respective
text box and hit search) like
emp.setId(idTextBox.getValue()) // it not null this time!!! say id is '*
1'*
RequestFactory complains *'The persisted entity with id '1' has null
version'
*So I tried to find a workaround by setting version to *'0' *or any number.
But in my EmployeeLocator I have this :
@Override
public Employee find(Class? extends Employee clazz, final Integer id)
{
return employeeDao.findById(id);// *Assume version is 21*. *bam!!
0 != 21 -- Autobean frozen! *
}
Which will return latest entity from database having the latest version.
Now if its now *'0' *, I mean if it does not match with the arbitrary
version set on client, the RequestFactory will again throw exception
complaining :
*The AutoBean has been frozen.
*
*
--x---x---x--x
*
*
*Is there any way I can tell RequestFactory:
'*Hey RequestFactory, chill !!!, don't make any checks and don't throw
any exception, this one is just for search purpose*'
Thanks in advance.

RequestFactory Sending EntityProxy with Associated Entites Fields as null
Hi all,
At first is it a necessity to use 'InstanceRequest' for persisting
Entites?
Anyway what I am doing is
_
client
creating a proxy - calling edit() [request.edit(proxy)] - set the data
to proxy e.g.
proxy.setName(name')
...
...//Also some where setting the field for associted type
...//how I get a countryProxy is like this
...requestCon.findById(123).fire
proxy.setCountry(countryProxy); // I am sure countryProxy has required
field. *checked for 'ID' i.e countryProxy.getId() != null
..
- call RequestContext appropriate method to save it to database.
request.save(proxy).fire.
__
On servier side..
public void save(MyEntiry me) {
me.getCountry() != null; //Yesss!!! country is not null ... there is
something
me.getCountry().getId() == null; //Yes!... Id field is null ... on
client side it wasn't
}
___
I need to load the associated entities to hibernate session at least it
could have given me ID. :(
At the same time an udate method is working fine somehow ... !!!
uses hbmSession.saveorupdate(.
may be its just ignoring associated nulls... I have to yet check it out.
I have a presentation for this app tomorrow...
Help!!!.
Please!

Re: RequestFactory Sending EntityProxy with Associated Entites Fields as null
Hi,
It's seems if I use the same RequestContext reference to create Proxy it
doesn't give a problem...
But what if I am getting a proxy from somewher else already populated with
values ...
is there a way to use that proxy or I just have to do all the setters and
getters to create new proxy from the existing one.!

Re: RequestFactory Sending EntityProxy with Associated Entites Fields as null
Pheww,
Caught the culprit... The Locators.
---
@Override
*public* MyDto find(Class? *extends* MyDto clazz,*final* Integer id) {
*return *new MyDAO.findById(id);//Earilier - return create(clazz);
}

Beware whenever you are going for the '*Eclipse RPC Generater.' *
Rather I am thinking now I could have saved a lot of time and done this by
using 'Reg-ex'

RequestFactory Eagerly Fetches the collections in my entity meant to loaded Lazy
Hi all,
RequestFactory seems to fetch whatever the collection I have in my
ValueProxy eagarly.
Lets see the code
@Entity
public class Venue implements Serializable {
private name;
private Address address;
private SetVenueContact contacts;
@OneToMany(fetch = FetchType.LAZY)
public SetVenueContact getVenueContactses() {
return this.contacts;
}
// other getters and setters
}
Lets assume I have set everything else for RequestFactory and Hibernate
(Hibernate standalone tests run fine) in order.
I call the below code from client:
requestFactory.venueRequest.findById(7).fire(new RecieverVenueProxy() {
public void onSuccess(VenueProxy res) {
log.info(I never get this :();
}
});
In service method
public Venue findById() {
//currently I am using a command pattern for a unit of transaction
but anyway I just write simply whats happening
// assume try catch and variable declaration code
session = HibernateUtil.getSessionFactory.openSession();
trx = session.getTrasaction();
trx.beginTransaction();
venue = veneuDao.findById(7);
trx.commit();
session.close();
}
##
Run Application and get this exception

collection of role: com.x..dto.Venue.contacts, no session or
session was closed

Why does the view need to be a singleton ?
I guess why I am having view as singleton is having better performance
as I see views are expensive to create.
Not creating em everytime saves operation deep down like
Document.create - appendChild. and so the DOM manipulation
that saves time.
Anyway, when you are done with the presenter, then you need to tell it so.
In that case it can unregister any installed handlers.
