Re: Hibernate session in RequestFactory
Hi Thomas, I already override isLive method and I return always true. I can't understand if is possibile to create an Exception and send it to the client from the class PersistenceFilter. Forgetting for a moment the question of how I manage sessions with Hibernate, I would like to know how I can raise and send an exception to the client from the PersistenceFilter class ie outside the context of the request.

Re: CellTable - add Anchors to a cell
Hi Thomas! FYI, that'd be even easier (and possibly faster) with UiRenderer. Event handling would be much easier, unless you really need that command identifier as a string approach. https://developers.google.com/web-toolkit/doc/latest/DevGuideUiBinder#Rendering_HTML_for_Cells This is available in GWT 2.5 right? Until now I never thought about using release candidates and classes that are subject to change. Would it be a good idea to use GWT 2.5 RC now? I use an enum now to represent these commands. But to attach them to a HTML tag the only way are attributes, and these are strings, or am I wrong? And as Juan Pablo said, you shouldn't use a for actions, use a button or a span and style it like a link if you wish, but do not abuse a. What's the problem with a?

CellTable - Synchronization problem with AsyncDataProvider
Hello,
I have a class UserListPanel, which shows a CellTable of users. When such
a panel is created it initially shows all existing users.
The set of users in the list may be changed by calling a method
setUserFilter, e. g. for selecting all users that match some criteria.
Then, the list is reloaded by calling
CellTable.setVisibleRangeAndClearData.
There is a problem, when setUserFilter is called immediately after class
instantiation:
UserListPanel p = new UserListPanel ();
RootLayoutPanel.get().add(p);
UserFilter f = new UserFilter (some criteria);
Window.alert (Test);
p.setFilter (f); // has no effect, when Window.alert above is omitted
In this case, the call to setFilter has no effect, i. e. the list shows all
users.
Note that within the AsyncDataProvider's onRangeChange a RPC call to the
server is made in order to fetch data from the database.
I assume that there is a synchronization problem with the asynchronous
calls and that they return in wrong order.
When I trace within onRangeChanged by opening a message box with
Window.alert, it works fine.
I also tried to put the reload method into
a Scheduler.get().scheduleDeferred, without success.
So I need to ensure that all open RPC calls have returned before the call
to setFilter is made.
How can I do that?
I would appreciate any hints.
Thanks
Magnus

Re: CellTable - Synchronization problem with AsyncDataProvider
Hi, I found out the following: When the second call to onRangeChanged occurrs, there are fewer records in the list than visible rows in the CellTable! The first rows are updated correctly, but the remaining visible rows are not cleared! So there is probably no synchronization problem, but a display problem: When after calling tbl.setVisibleRangeAndClearData there are fewer rows than visible rows, the remaining visible rows are not cleared. When the data comes in it is pushed into the table by a call to provider.updateRowData. At this moment: How can I ensure that the remaining rows are cleared and why does not CellTable clear them?

Gin module binding using annotatedWith and AsyncProvider
If I want to inject an instance of a specific class based on an annotation,
I can do this in a Gin module:
bind(DiSecondary.class).annotatedWith(Special.class).to(DiSecondarySpecialImpl.class);
I also already have:
bind(DiSecondary.class).to(DiSecondaryImpl.class);
I can then retrieve the special instance into my DiMain (Composite wrapping
a Panel) constructor with:
@Inject
public DiMain(@Special DiSecondary special) {
add(special);
}
But, if I want to code-split DiSecondarySpecialImpl using AsyncProvider,
the analogous approach does not work:
@Inject
public DiMainAsync(@Special final AsyncProviderDiSecondary
diSecondaryProvider) {
diSecondaryProvider.get(new AsyncCallbackDiSecondary() {
public void onFailure(Throwable caught) {}
public void onSuccess(DiSecondary result) {
add(result);
}
});
}
I get a GWT compiler error. If I remove the annotation, then, of course, I
get the non-special implementation.
Am I being unreasonable to expect that the compiler could apply the
annotation to the async provider for the base class instead of the base
class itself?
Is there a different route that I can use to get the desired behavior
(annotation-based selection of an alternate async loaded class)?

Re: CellTable - Synchronization problem with AsyncDataProvider
I have a similar post. I was trying to do something as simple as when
I click on a refresh button to completely clear my provider and
display the freshly received entities from the server. I haven't had
time to go back and look at it, but I would also be interested in
getting a definitive idea as to what the right approach for reloading
a CellTable should be. I not only want to get say 1000 rows and change
what gets displayed by manipulating the visible range. I am talking
about completely clearing my provider and repopulating it with freshly
received objects. I would think a simple clear() and add() in the
provider would do, but it doesn't seem to be that simple. The provider
clears and adds the new list of objects but the display never updates
it. I tried a handful of things to force a resync of the display and
nothing.
I read a whole lot of stuff online and there seems to be many people
confused in this area. I started to dive in also and investigate in
the code, but never finished it. There are a handful of methods that
all look similar but do different things.
My post can be found at:

SuggestBox works best if you use the ID as the replacementString and the
label as the displayString of the Suggestions in your SuggestOracle. In
that case, you don't have to do anything, the ID will be set in the text
box upon selecting a suggestion.
(e.g. the replacement string is an email address, and the display string
also contains the full name, the oracle using both the full name and email
address for providing suggestions)

Re: UiBinder ERROR: Attribute 'from' does not have a computed value Element
I know that one can take the
DevGuideUiBinderI18nhttps://developers.google.com/web-toolkit/doc/latest/DevGuideUiBinderI18n
approach but this seems like such overkill. I merely want to leverage
constants in a properties file directly in a ui.xml file.

SimplePager last page issue
Hi,
There is a bug with SimplePager that enable go to next page in the last
page (an must be disabled). Well, after some debugging if I change the
method onRangeOrRowCountChanged() in this way works well.
@Override
protected void onRangeOrRowCountChanged() {
HasRows display = getDisplay();
label.setText(createText());
// Update the prev and first buttons.
setPrevPageButtonsDisabled(!hasPreviousPage());
// Update the next and last buttons.
//if (isRangeLimited() || !display.isRowCountExact()) {
if (isRangeLimited() || *display.isRowCountExact()*) {
setNextPageButtonsDisabled(!hasNextPage());
setFastForwardDisabled(!hasNextPages(getFastForwardPages()));
}
}
As see, I remove ! in display.isRowCountExact() and works. Hope helps
someone.

GWT Frame Load Wrong Page in IE 8 (Different Than The URL Showed In URL Toolbar)
Hello everyone, I have a GWT Application that use couple of GWT Frame to load other site content. Let say in the left side of my application I have tree menu, and every time user click one of those menu, it will open a new tab in the right side of my application, and in the tab item, it will load other site content. Let say first I click tree menu A1, the application then open a new tab item in the right site with URL http://application.first.com/first.aspx. After that I click the other tree menu B1, the application then open a new tab item in the right side with URL http://application.first.com/second.aspx. After that, I hit the F5 key, and the browser reload again. Then I repeat the step from the beginning, when I click tree menu A1, the application open a new tab item in the right side, but the content that loaded is from http://application.first.com/second.aspx, but when I do right click in the frame area, it will show me that the currently accessed URL is http://application.first.com/first.aspx. Have anyone ever experience this problem? Because I really stuck in here, the other major browser working just fine (FF and Chrome), only IE 8 that give me this problem. Any comment and advice will be appreciated. Thanks. Regards, the.wizard -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: CellTable - Synchronization problem with AsyncDataProvider
Hello, I found this interesting article: http://turbomanage.wordpress.com/2011/03/02/gwt-2-2-asyncdataprovider-celltable-gotcha/ It also states that one should always update both row count and row data. But when looking to the code in the article, it seems that the author assumes that AsyncDataProvider.updateRowCount expects the number of *visible* rows. My understanding is that it expects the number of *total* rows. Is this correct? However, I cannot call both at the same time with the exact values. I have to make two different RPC calls, one for the data in onRangeChanged, and one to fetch the total record count. As I posted before, I call updateRowCount(0) on reload, just to be sure that old rows disappear. Later, when the RPC call for the row count returns, I call updateRowCount with the exact number. Unfortunately the old rows still remain visible after reload... Magnus -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: UiBinder ERROR: Attribute 'from' does not have a computed value Element
An compile error like can't implement the constants interface: It must
implement TextResource or _. I forget the other type the error states.
My semantics here are:
interface MyResources extends ClientBundle {
@Source(MyConstants.properties)
MyConstants constants();
}
where MyConstants interface is auto-generated via the gwt-maven-plugin.
