Re: GWT 2.4 editor framework ui for create weak one2many relation

2012-05-09 Thread Human izatara

thanks for your attention Brandon !
I didn't understand your first way completely. I don't use App engine.
our application use spring and jpa and I use eclipse and currently we
run application on jetty.
in our previous application, we used jsf and we could implement such
scenarios for entities with owned collection and after copying
collections from ui into entity, hibernate handle persisting entity
and it's owned collection and we didn't do anything. in that
application when we annotate a property with cascade="all-delete-
orphan" and ask hibernate to save(entity), it saves it's owned
collections too.

I want to know how to implement such scenarios, when we use gwt 2.4
with editor framework. and is there any sample or tutorial for doing
this on web ?

Re: How to determine CellTable row height?

2012-05-09 Thread Mike Dee

Andrei,

That's a good response.  I think you convinced me to not do it.

Instead, I wonder if it is possible to do something like what other web 
apps do (Twitter and even the new GWT google group), which is to keep 
adding rows as one scrolls down.  I've experimented with range change event 
handler.  Maybe that would be a more modern way to provide tabular data?

Re: GWT, Spring when projects are split apart (client, services, persistence)

2012-05-09 Thread Christien Lomax

Hi Thomas,

First, I want to say that your examples and blogs have helped us a lot over 
the last year!  Thanks!

Secondly, thanks for the super quick reply!

I added the sources generation to the POMs for the Shared, Persistence and 
Services projects, and fixed the ".class" issues.  However, we are still 
getting issues with GWT not being able to find classes/sources...  they (at 
the moment) seem to be around classes specified via @ExtraTypes which we 
have specified in our IAppRequestFactory interface.

eg:

@ExtraTypes({
IAlertProxy.class, IAlertOptionsProxy.class, IAlertTypeProxy.class
})
public interface IOris4RequestFactory extends RequestFactory
{
IAlertRequest alertRequest();

...
}

The specific error is:
   Resolving com.mycompany.client.IAppRequestFactory
  Found type 'com.mycompany.client.IApp4RequestFactory'
 [ERROR] Annotation error: cannot resolve com.mycompany.
client.alerts.proxy.IAlertProxy
   java.lang.ClassNotFoundException: com.mycompany.
client.alerts.proxy.IAlertProxy
   ...
   [ERROR] Annotation error: expected class java.lang.Class, got null

It then eventually down the list starts complaining about the Adapters

Resolving com.mycompany.client.alerts.proxy.IAlertProxy
  Found type 'com.mycompany.client.alerts.proxy.IAlertProxy'
 [ERROR] Annotation error: cannot resolve com.mycompany
.adapter.alert.AlertGwtAdapter
  java.lang.ClassNotFoundException: com.mycompany
.adapter.alert.AlertGwtAdapter

The proxy classes are specified in the main client project, and the adapter 
classes are in the same project, but outside the client package (referenced 
via )

Sorry to bother you again about this, but its had us stuck for a while now.

No problem, but keep in mind that you now have two browser history entries 
which are both the same. So you should not use this throughout your app if 
you need to reload things otherwise the browsers back/forward buttons would 
feel odd. For login its probably ok.

Re: 2 RequestFactory with 2 differents Proxy on the same domain class

2012-05-09 Thread Thomas Broyer

Yes, please file a bug for that.

If you can contribute the patch to gwt-code-reviews.appspot.com it'd be 
even better (see 
https://developers.google.com/web-toolkit/makinggwtbetter#contributingcode)
As far as the patch goes, your processing loses the "most-to-least-derived 
type" ordering of the domainToClientType values that 
Deobfuscator#getClientProxies mandates.
See 
http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/web/bindery/requestfactory/apt/TypeComparator.java
 for 
the ordering, to be ported to Class 
(see 
http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/place/rebind/MostToLeastDerivedPlaceTypeComparator.java
 
for an almost-equivalent)

You could copy the PlaceController.goTo() method and omitting the

2 RequestFactory with 2 differents Proxy on the same domain class

2012-05-09 Thread Alexandre Ardhuin

Hi All,

I have an application with 2 gwt modules. Each module uses its own
RequestFactory and its own Proxy for the same domain object (ie. 2
RequestFactory with 2 differents Proxy on the same domain class).
The first RF call succeeds and following RF of the same type too but when
the other RF is used an exception occurs :
"The domain type Xxx cannot be sent to the client"

After some tests, the problem occurs only for 2 RF. Having only one RF with
2 Proxy on the same domain object works well.

The problem seems to be in
com.google.web.bindery.requestfactory.vm.impl.Deobfuscator.Builder.merge(Deobfuscator).
Doing the following modification resolves it.

public Builder merge(Deobfuscator existing) {
+  Set domains = new HashSet();
+  domains.addAll(d.domainToClientType.keySet());
+  domains.addAll(existing.domainToClientType.keySet());
+  for (String domain : domains) {
+Set clientTypes = new HashSet();
+clientTypes.addAll(d.domainToClientType.get(domain));
+clientTypes.addAll(existing.domainToClientType.get(domain));
+d.domainToClientType.put(domain, Collections.unmodifiableList(new
ArrayList(clientTypes)));
+  }
-  d.domainToClientType.putAll(existing.domainToClientType);
  d.operationData.putAll(existing.operationData);
  // referencedTypes recomputed in build()
  d.typeTokens.putAll(existing.typeTokens);
  return this;
}

Can someone confirms this is a bug ? (I haven't found any issue on that)

Re: How to determine CellTable row height?

2012-05-09 Thread Andrei

If your data never wraps within a cell, then the height of the row is
always the same - it is determined by the CSS. (As a sidenote, you can
change it in your CSS, or even apply different heights to different
tables).

Else,

1. The height changes as data wraps within a cell. Thus, you can't
know the actual height of the row until the table is rendered.

2. If the height changes with data (some rows have longer data and
wrap, other rows don't), what's the point of changing the number of
rows? Your first 10 rows may take 240 pixels, the next 10 rows can
take 330 pixels, and so on.

Also, remember that data can wrap more often when columns are
narrower. This means that if you want to predict the height of your 10
rows, you also need to take into consideration the width of each
column.

3. Users can change the size of the font in their browsers, unless you
disable it, which is not a good practice. They can also resize their
windows, add or hide toolbars in their browsers, etc. You just can't
avoid having a scroll-bar.

FilteredActivity

2012-05-09 Thread Thomas Lefort

Hi,

I have the following issue: I use a FilteredActivityMapper with the 
following filtering:

@Override
public Place filter(Place place) {
if(// check user is logged in) {
return new EIRegisterPlace("", place);
}
 return place;
}

Filtering works well except that when the user logs in I call 
placeController.goTo(nextPlace) and the code gets stuck. The reason is that 
the "where" variable is still set to the old place (and not the 
EIRegsiterPlace), so where = nextPlace and the placeController gets blocked.

Any idea if this normal (that the place doesn't change to 
"EIRegisterPlace")? and is there a workaround? another way of proceeding?

Thanks,

Thomas

You ahve to produce a source JAR for your artifacts, and then reference 
them as dependencies in your GWT project.
See 
https://github.com/tbroyer/gwt-maven-archetypes/tree/master/modular-requestfactory/src/test/resources/projects/basic-rf/reference
 for 
an example (here, the GWT client-side, server-side, and shared code 
–RequestFactory interfaces– are separated into 3 distinct modules; the 
client module depends on the shared module's 
sources to bring its sources in the GWT compiler 
classpath.

Don't include the ".class", it's not part of the name of the class.

This is the default in GWT 2.4 AFAIK (or will it only be starting with 2.5?)

Re: GWT, Spring when projects are split apart (client, services, persistence)

2012-05-09 Thread Jens

How do you compile your app? Maven? Ant? In Eclipse using GPE?

You have to make sure that the GWT compiler's classpath contains all needed 
source files (= add src/main/java of all projects that need to be compiled 
by GWT to the compilers classpath).

GWT, Spring when projects are split apart (client, services, persistence)

2012-05-09 Thread Christien Lomax

Hi All,

We could use a bit of insight and help if anyone has a moment.

We currently have a project that is quite huge (thousands of classes) 
including the GWT client, a spring service layer and 
hibernate persistence layer.

We are trying to split up the project into more manageable pieces including:

   - client project (contains our GWT widgets, RequestFactories, etc, 
   Spring servlets)
   - service project (contains the spring service layer, web services 
   (REST, SOAP))
   - persistence project (contains the domain beans - hibernate mapped 
   objects, persistence code, etc)
   - shared project (classes that can be used on both the client (gwt 
   compiled) and server side.

Everything compiles and works (unit tests, etc) until we hit GWT's compile. 
 At this point, we get complaints about GWT not being able to see items 
in the service layer (which makes sense, it is trying to compile references 
to the beans, services, etc).
We've tried a number of approaches, including using @ServiceName instead of 
@Service and using the  specifications on the modules.  Right 
now we a few errors we are unable to resolve:

1 - we get this one for every Adapte:)
  [ERROR] Errors in 'file:/C:/workspace/client/src/main/java/com/
mycompany/adapter/alert/AlertBeanGwtAdapter.java'
 [ERROR] Line 14: No source code is available for type 
com.mycompany.service.alerts.IAlertService; did you forget to inherit a 
required module?

2 - if we omit the "-strict" parameter when compiling GWT, we get this:
 [ERROR] An internal compiler exception occurred
 com.google.gwt.dev.jjs.InternalCompilerException: Failed to get JNode
 ...
 [ERROR] : public interface com.mycompany
.service.alerts.IAlertService
 ...
 org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding
 [ERROR] at AlertBeanGwtAdapter.java(14): private IAlertService 
getService() {
   return (IAlertService) 
EcmLocator.getApplicationContext().getBean(IAlertService.TYPE);
 }
 org.eclipse.jdt.internal.compiler.ast.MethodDeclaration

Can anyone shed any light on what we may be doing wrong?  When it is all in 
one project, everything works fine, but splitting it into multiple projects 
(that are references via maven) it fails.

Example source (some code is omitted):

*Client Layer:*

*...client.alerts.request.**IAlertRequest.java*
@ServiceName(value = "com.mycompany.service.alerts.IAlertService.class", 
locator = "SpringServiceLocator.class")
public interface IAlertRequest extends RequestContext
{
Request countAlerts(String eventClass, Date dateLimit);
Request> listAlertTypes();
Request> listUnviewedAlerts();
}

*...web.**SpringServiceLocator.java**
*
public class SpringServiceLocator implements ServiceLocator
{
 public Object getInstance(Class clazz)
{
ApplicationContext context = 
WebApplicationContextUtils.getWebApplicationContext(RequestFactoryServlet
.getThreadLocalServletContext());
return context.getBean(clazz);
}
}

*OurProject.gwt.xml*












 










*Service Layer:*

*...services.alerts.**IAlertService.java*
public interface IAlertService
{
String TYPE = "AlertService";
Long countAlerts(String eventClass, Date dateLimit);
List listAlertTypes();
List listUnviewedAlerts();
}

*...services.alerts.AlertService.java*
@Service("AlertService")
@Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
public class AlertService extends EcmService implements IAlertService
{
public Long countAlerts(String eventClass, Date dateLimit) {...};
public List listAlertTypes() {...};
public List listUnviewedAlerts() {...}; 
}

*Persistence Layer:*

*...domain.alerts.AlertBean.java*
@Entity
@Immutable
@Table(name = "alertdisplayview")
public class AlertBean implements Serializable
{
 ...
}

*...domain.alerts.* *AlertType.java*
@Entity
@Immutable
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
@Table(name = "alerttype")
@NamedQueries({
@NamedQuery(name = "alertType.findByName", query = "select alt from 
AlertType alt where alt.name =:name or alt.internalName =:name")
})
public class AlertType implements Serializable
{
 ...
}

*Persistence.gwt.xml*

GWT: CheckBoxCell and Selection change event

2012-05-09 Thread Qrunk

I am using the following constructor to create a checkboxcell in an 
editable data grid.
   
*CheckboxCell(false, true)*

When I use this and click at any place in the row, selection change event 
does not fire and I am using *Single selection model* .

When I use,

*CheckboxCell();*

Selection change event fires on the row but,
1) We have click twice to check or uncheck the check box cell.
2) if we check or uncheck in the checkboxcell, the value will reverted as 
soon as I click anywhere.

I am trying to figure out the solution, but not successful yet. Any help 
would be appreciated. 

Am using  *GWT 2.4.0 *

Sure its possible. GWT/RF does not make any assumptions about the database 
you are using.
