No other changes in the program given by the GWT web application
starter project
I have deployed the files inside the WAR folder to the prism folder of
my server
so that i can access my app by typing www.yellowlemon.in/prism/Rpctesting.html
But the server fails to map my servlet.
can you tell me ,where i have to change ?
url-pattern/rpctesting/greet/url-pattern
You said The url-pattern must be context-relative . I did not get
this line
i think the problem happening on the above line . It works fine on
local machine but not on server
Yes as you said rpctesting is the module name . and in the server log
i am getting error like
File does not
exist: /home/spectrum/public_html/prism/rpctesting/greet, referer:
http://yellowlemon.in/prism/Rpctesting.html
Hope you can help me on this.

The problem is nothing to do with GWT, or really, Tomcat for that

the path:

The things to check are:
@RemoteServiceRelativePath in your RPC
I suspect that it probably looks like:
@RemoteServiceRelativePath(greet)
and then the web.xml file for the server should look something like:
!-- servlets --

Where your GWT project is XXX.
The url-pattern must be context-relative. What is often confusing about this
is that the default Jetty implementation in the development
mode has a context of /, but when you deploy it to tomcat by default the
context becomes the name of the war, which is often also
the project name.
Consequently the actual request looks something
linkwww.myserver.com/XXX/XXX/greet. This is because the context relative path
for the JS files which make up your project are, by default, in a folder with
the same name as the gwt.xml module, or its 'shorthand' module name. Since
its common to make the module name the same as the project, the war ends up
with the same name as the module, and the deployed context is the project
name. Confused? Maybe this

Thank you, but it is not clear yet:
Could you please mention the class that I should subclass?
And what should I use instead of TextCell?
Thanks!

Re: How to add a link (anchor) to a CellTable?
You will use the Column class directly and tell it to use your custom cell:
Column col = new ColumnEntry, String(new YourCustomCell()) {
@Override
public String getValue(Entry obj)
{
return (obj.myAttribute);
}
}
How to implement a custom cell can be found in the documentation.
If you only need a simple link you could also just use the SafeHtmlCell:
public interface SimpleCellTemplates extends SafeHtmlTemplates {
@Template(a href=\{0}\{1}/a)
SafeHtml anchor(SafeUri href, String name);
}
static final SimpleCellTemplates cell = GWT.create(SimpleCellTemplates.class)
Column col = new ColumnEntry, SafeHtml(new SafeHtmlCell()) {
@Override
public SafeHtml getValue(Entry obj)
{
SafeUri href = //construct your href as SafeUri using UriUtils
return cell.anchor(href, obj.getName());
}
}

Activity / Place + History.back()
I'm having an issue where the History.back() is intermittently not working. I'm using Places mapped to each activity in my application and navigating forward works great. For instance lets say we start out on #search-#result. If I programmatically use History.back() as a button in my application to return the the #search it occasionally does not load the #search page even though the url bar reflects the action. I've debugged the code and have tracked down where the problem is, just not 100% why. The PlaceHistoryHandler class listens for ValueChangeEventString from the browser which is fired when the History.back() is called. This in turn calls the PlaceHistoryHandler.handleHistoryToken(...) method which calls the PlaceController.goTo(Place) method. THe PlaceController.goTo(Place) method is doing an if check if where == place and if so returns without firing a PlaceChangeEvent. That if check is causing the ActivityManager not to fire it's onPlaceChangeEvent, which in turns makes it so that the previous activity is not restarted for handling the #search place. As I said sometimes it works, sometimes it doesn't. It's all based on the if check for where == place though as to the outcome. I know for a fact by staring at the url bar that there is a change. So is this a bug that others have see or am I doing something wrong? Any help would be appreciated. -Adam -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Local data cache when using AsyncDataProvider (CellTable)
Well I have an application in which I display 1.2 million items in a CellTable (50 items at a time). I solved that by using AsyncDataProvider and doing bulk-requests of around 2000 items (you can play with that vaue). I have a SimplePager which displays 50 of them at a time and when the user pages through it it won't do any server request until the list of 2000 is completed. Then I request the next 2000 items (actually that is automatically taken care of by the AsyncDataProvider interface). For filtering/searching I implemented a hybrid approach. For example if the user types in a string for a name it will first search on the server. Again only 2000 items will be sent back from the backend. For each new character I will do another server-request. However I also return the number of hits (which the search returns). If the number of hits is smaller than 2000 the next time the user types in another character it will only search on the client side (because I already have the whole search set transfered to the client). For sorting you can take the same path. To be honest I am not sure if it's worth just sending the IDs and then replacing it later with a second call with the missing real objects. I don't think it will be much of a performance problem even when you have a lot of user requests at the same time. You can try to solve that problem on the backend (via caching, etc) and if you still have an issue you can implement your approach.

Re: Activity / Place + History.back()
So I solved my problem. We'd created a convience method that called EventBus.fireEvent(new PlaceChangeEvent(Place)) instead of using the PlaceController.goTo(Place). This was causing issues because even though it felt the same it wasn't updating the where Place property of the PlaceController so when History.back() was called it was checking against a stale where object. -Adam On Jan 28, 12:44 pm, Adam ambr...@gmail.com wrote: I'm having an issue where the History.back() is intermittently not working.

Re: Can AutoBeanFactory encode ListBeanObject ???
You are on the right track for this, but you need to wrap each model with an autobean: encodeBean.as() is not the same instance as t1, even though it is obtained from the autobean that wraps t1. You need to wrap each instance, and include the wrapped instance in the eventual tree to be encoded. The list may also have trouble, it has been a while since I tried to build something like this out. The approach I've taken, rather than manually wrap the whole tree, was to wrap the root object, and use an autobean visitor to walk the rest of the properties, wrapping and continuing further down the tree. I found the code in com.google.web.bindery.requestfactory.shared.impl.AbstractRequestContext.cloneBeanAndCollections(AutoBeanT) to be helpful as a guide when copying autobeans, along with other aspects of the internals of RequestFactory, which is based on Autobeans for transport. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: input in MenuBar implementation
Unfortunately when I set the menu to *position:absolute, top:0, left:0*this nasty input does cause troubles: it makes the menu stick 1px over the right edge of the page which naturally causes horizontal scroll-bar to be dran by the bottom edge of the page.
