Re: Use SuggestBox suggestions in another widget

[Johannes Barop]

Hi,

the best code to refer is the source code of SuggestBox itself.

Having a look at this constructor you'll notice an interface SuggestionDisplay. 
The default implementation uses a MenuBar to display a list of text items. You 
can easily implement any custom rendering by implementing this interface and 
passing it to the SuggestBox's constructor.


Cheers,
Johannes

Re: Memory growth in GWT Compiler

[Ranjith Chungath]

I compiled it with 2GB without memory dumping and as you 
mentioned, System.gc() was called and the graph was uniform similar to my 
second graph.
 
Thanks,
Ranjith

How to get Map InfoWindow Scrollbar to show

[Matt Nolan]

I'm using java for a map application, and I have a rather long string to be 
shown in an infowindow.  The window that displays overflows and overlays 
the map while the infowindow is open.  I'm wondering how I can add a 
vertical scrollbar to the infowindow.

Re: GWT website moved to gwtproject.org

[maticpetek]

Hi,
  Great work. Maybe Google should include some links also 
on developers.google.com for GWT (gwtproject.org) - like they do for Dart. 
For example :
1) https://developers.google.com/ -> page footer -> "Other references"
2) https://developers.google.com/ -> "Products" -> "Web developer" -> left 
menu. It their is place for Dart, it should be also for GWT. 

Regards,
   Matic

GWT website moved to gwtproject.org

[Daniel Kurka]

Today we finally flipped the switch and moved all the GWT content from 
developers.google.com to gwtproject.org. The old homepage will redirect to 
gwtproject.org so there should be no broken links. However if you encounter 
any missing content or broken links please file a 
bug
.

Why did we do this?

GWT is now an open source project and we wanted to enable people to 
contribute to the website and documentation as well. Since 
developers.google.com can only be updated by Google employees we needed 
another home.

Re: Use SuggestBox suggestions in another widget

[Kartik Suba]

Hey you can easily make Customized Suggestion box and also a Customized 
Display associated with it that will show the suggestions in the panel 
where ever it is. I have already implemented a Custom Suggest box as I 
wanted the SuggestionList to be displayed even when nothing is entered. So 
that I can easily extend and incorporate your functionality. Do try making 
customized one altogether. Do let me know if you needa code for reference.

Re: How to avoid freezing with CellTable?

[Kartik Suba]

Hey you can use the pagination that is available with the cell table. Also 
I have also implemented a more functionality that loads for example 25 
records and when the scroll reaches it lower bottom i again load 25 and 
append more in the same table. The problem when there is more data is not 
because the call it taking time, but as everything is javascript the 
browser overloads and hangs. So see if this could help. Do mail me again if 
you need the more function as a reference.

Please let me know if you find this info useful. :)

Re: RF, ServiceLayerDecorator : The domain type com.test.persistance.entites.base.BaseTest cannot be sent to the client

[Thomas Broyer]

IIUC, in your resolveClientType, when called with Test.class will pass 
BaseTest.class down the chain, and you have no proxy associated with 
BaseTest (MvtProxy is associated with the Test class)

I have no idea what your decorator is meant to do; as it is, it seems more 
harmful than helpful.

RF, ServiceLayerDecorator : The domain type com.test.persistance.entites.base.BaseTest cannot be sent to the client

[aurelie . virgile]

Hi there,

Sorry about this long question.

I do experience some difficulties playing with GWT RF. ( *keywords*: Gwt 
,Hibernate, Valueproxy, Locator, ServiceLayerDecorator)
i am beginner level.
Will try to be as accurate as possible but i probably may have 
misunderstood a couple of things and some typo errors can appear because 
code is simplified.

In brief, when RF is trying to send datas back to the client, i 've got an 
error.

com.google.web.bindery.requestfactory.server.UnexpectedException: The 
> domain type com.test.persistance.entites.base.BaseTest cannot be sent to

Call is made by

requestFactory.createMvtRequest()

Receiver used  ( extract )

Receiver> rec = new Receiver>()

*In details :*
*Client Side *
   
   -  Widget
   -  Factory  @Service(value = MvtService.class, locator = 
   MvtServiceLocator.class)
   -  MvtProxy as ValueProxy( @ProxyFor(value = Test.class, locator = 
   MvtLocator.class) 
   
   * Persistance Side*

   -  Test ( public class Test extends BaseTest )
   -  BaseTest ( public class BaseTest  implements Serializable )
   
*Server Side*

   - MvtService (public class MvtService)
   - MvtServiceLocator (public class MvtServiceLocator implements 
   ServiceLocator)
   - CEMMvt (public class CEMMvt)
   - MyDecorator (public class MyDecorator extends ServiceLayerDecorator)
   - MyRequestFactoryServlet (public class MyRequestFactoryServlet extends 
   RequestFactoryServlet)  Replacing RFServlet in web.xml
   
*Others infos* 

CEMMvt list() method is using a DAO to get the datas from a database and 
returning a List. It is well populated.

I previously had the same error 
"com.google.web.bindery.requestfactory.server.UnexpectedException: The 
domain type com.test.persistance.entites.Test cannot be sent to the client"
Seems to be resolved by using MyDecorator but whats am i doing wrong in 
this particular case ?

Many thanks for pointing me in the right direction.

Regards,

pierre

Re: How to avoid freezing with CellTable?

[Ümit Seren]

2-3 minutes ? There must be something seriously wrong because there is no 
way it should take so long to populate a CellTable. 

1.) Profile your web-app. What does take so long (serialization or 
rendering)? use Chrome Dev Tools to do that. 
2.) Use paging. From a UX point of view it doesn't make sense to show all 
rows at once. 
3.) Transfer chunks of data (using AsyncDataProvider) because as of point 2 
the user doesn't need to see all rows at once.
