Suggestbox suggestions not displayed when navigating using arrow keys

2012-05-02 Thread ALB-PSP-DV1

We have a suggestbox with approx. 50 suggestions. We are displaying a
scrollbar for the suggestbox using the following css

.suggestPopupContent{
height:auto;
width:auto !important;
max-width:400px;
max-height: 165px;
overflow-y: auto;
padding-right:18px;
}

Now when the user tries to navigate through the suggestions using the
Up/Down arrow key, the suggestions not within the current visible area
are not displayed.

Thanks in advance.

Aha, got it !

  Hi everyone, now that i am working with GWT i am facing a problem with
  the event handling mechanism the first problem was (

 http://groups.google.com/group/google-web-toolkit/browse_thread/threa...
  ), but when i read this article MVP II (
 https://developers.google.com/web-toolkit/articles/mvp-architecture-2
  ) - actually i read it several times - i still don't understand when u
  to use EventBus mechanism and when not ? and if i have to use when u
  use EventBus Handler and HandlerManage ?.
  Here is what confuses me:

  public class ContactsPresenter implements Presenter,
  ContactsView.PresenterContactDetails {
  ..
  public void onAddButtonClicked() {
      eventBus.fireEvent(new AddContactEvent());
    }

    public void onDeleteButtonClicked() {
      deleteSelectedContacts();
    }

    public void onItemClicked(ContactDetails contactDetails) {
      eventBus.fireEvent(new EditContactEvent(contactDetails.getId()));
    }

  
  }

  Why one method fires and event and the other just do some logic witch
  is defined the class ?

  Thank you all for your replies.

  the source code of the example is here :

Re: How to build text trimming cell for GWT DataGrid

Works good, thanks!

 @Jens,

 Just to expand on Jen's answer. For this solution to work, you need to
 apply it to a div inside a cell:

 .myDataGrid td div {
     white-space: nowrap;
     overflow: hidden;
     text-overflow: ellipsis;







 }
  Apply CSS to your cell:

  white-space: nowrap;
  overflow:hidden;
  text-overflow: ellipsis;

Apache Proxy 500 error or RPC serialization

2012-05-02 Thread Kulnor

I'm trying to proxy a GWT app running on my local Tomcat server through 
Apache use AJP but am getting 500 errors during RPC calls.

I simply have a standard entry in my httpd.conf file:
Location /user/
ProxyPass ajp://localhost:9009/openmetadata-www-user-gwt/
/Location

When I run the app directly on 
http://localhost:9090/openmetadata-www-user-gwt/ I have no problem, but 
when I go through the proxy, I can see the RPC call go through but then 
getting serialization errors while returning objects:

SEVERE: Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type 
'org.openmetadata.www.user.client.UserServiceException' was not assignable 
to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a 
custom field serializer.For security purposes, this type will not be 
serialized.: instance = 
org.openmetadata.www.user.client.UserServiceException: User not found

Tried with http proxy (and on standard ports) but same issue. Seem like an 
RPC serialization policy problem but not sure what to do. Any suggestion 
would be appreciated.

Re: Apache Proxy 500 error or RPC serialization

2012-05-02 Thread Kulnor

The source of the problem seem to come from the fact that the proxy site
URL is different from the GWT app URL. This is discussed and nicely
documented in
https://groups.google.com/forum/?fromgroups#!searchin/google-web-toolkit/proxypass$20serialization/google-web-toolkit/3wE9yWLMJo4/Mebd0XgW1EIJ
(thanks
to the authors for this!)

The following proxy setting works properly as the URL are the same:
Location /openmetadata-www-user-gwt/
ProxyPass ajp://localhost:9009/openmetadata-www-user-gwt/
/Location

In my case, I can rename the underlying GWT app on tomcat so that should
solved the issue. The post above provide excellent alternate solutions.
