Re: Hibernate session in RequestFactory
Hi Thomas, I know that a session is different from a transaction. But in my case I need also a single transaction per request in order to manage correctly the lazy entity with hibernate. The problem is that I can't send error message to the client when the error is on PersistenceFilter. Any ideas?

Anyone used GWT with Require.js?
Hi, The project I'm working on is seeing a lot of native Javascript creeping in, largely as a result of the requirement to incorporate UI features developed by other teams that specialise in Javascript. I am hoping to manage the Javascript dependencies using require.js (http://requirejs.org/). Correctly used, require.js will remove the problem where a script loads, executes, and fails because of a reference to another script that hasn't finished loading yet. But I still have problems when JSNI code calls into a Javascript library before it's finished loading. The solution would appear to be to use require.js to load the nocache script that boots the application, so that it won't start executing until all its dependencies have loaded. Does anyone know if this is possible? Any advice? Thanks, Chris -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Errai Experience?
Used in a number of real projects. API is very good and straight forward, dev team support also great. I was able to employ web sockets on one project which really made it fly. Real-time financial price distribution. The server side is wired up using Guice, which we struggled to sensibly(ended up statically accessing stuff) make work with Spring, so could do with a bridge there. I wouldn't necessarily recommend the GWT RPC substitute. While it works, it synthesis's subscription requests under the hood, so one simple call results in a number of http requests. (subscribing and unsubscribing) to a GWT RPC single call. Played havoc with ntlm and IE, re-authenticating every post requests. Firebug/Chrome dev tools very handy to see what's going on.

CellBrowser EditTextCell (not refreshing the cell)
Hi, I have changed the CellBrowser sample in showcase to render an EditTextCell for one of the columns. I would like to ignore the value change in EditTextCell in certain occasions. If the value entered by user in the EditTextCell is not acceptable, I would like to revert back to the original value that it was already rendering. I have read multiple posts about refreshing the cell table but none of them prevents the EditTextCell to change its value or at least set it to its original content. Note that the backed data provider has not changed, in fact if you click on the EditTextCell two times, it automatically reverts back to the original value but refreshing the EditTextCell data provider or it's parent data provider or closing / reopening the cellBrowser has no affect. I tried to extend the EditTextCell and override onBrowserEvent method but I can't seem to find a way to set the content of the cell to it's original value. Any help would be greatly appreciated.

Re: Drag and Drop UI using GWT with Connectors
Sorry for the late reply. Thanks for your inputs. Unfortunately, we do not have the privilege to use HTML5 and CSS3. As we may also have to support IE8... @Rob: I have looked into few of those sites. Mostly it is about integrating drawing tools into our application. I am not sure, how we can use it in our applilcation. First, can we integrate them along with GWT. Second, programmatically draw the diagrams, give a Drag and Drop feature for the diagram, handle connectors..etc. It would be really great if we have suggestion with this design. Now, I have looked into lib-gwt-svg API. But, using which we can draw diagrams. But still, not enough documentation on how to make use of api.

This is the technique yahoo also uses with its pipes project You can implement drag and drop using techniques provided for any gwt widget. I have implemented connectors in my project. All you have to do is place your widgets using absolute positioning on a panel (call it the editor), draw the connector to a canvas between the widgets and add the canvas to the editor.

Paging HTML viewer
I'm using the HTML widget to render some dynamic conversation logs. The problem is these logs can grow over time and add lots of DOM Nodes. I'm wondering if someone has made some sort of a paging HTML viewer? Currently I wrap the HTML widget in a GXT VerticalLayoutContainer with vertical scrolling, but could have used GWT ScrollPanel I presume. So I'm only showing a portion of the HTML at a time anyway so seems like paging would be an ideal solution. One trick, it seems, is that you have to calculate how big (tall) each portion of the HTML is so you know what portion to show when scrolling. This seems like it would be very useful general purpose GWT widget so I'm wondering if someone has made something like this already.

Re: display GWT dialog when a link is clicked in jsp
there are a lot of links that represent records Option 1) Have GWT consume this section - i.e. the jsp page contains an empty div with an id that can be picked up during GWT module load ( RootPanel.get(theId) ). The records would then be rendered via a gwt-rpc call into a gwt grid or table component. You can then use the anchor handlers for the Dialog that you already built. Option 2) Have gwt bootstrap from the jsp but without consuming any section. Add a javascript onclick to your jsp record to call a native javascript function which performs a jsni call for your loaded gwt module to open your dialog. Option 3) Have gwt consume a div with a hidden overlay (a dialog) . Add a javascript onclick to your jsp record to call a native javascript function which performs a jsni call to the loaded gwt module to provide context and reveal the dialog I prefer Option 1 as it leaves the page much more extensible for java developers to provide additional RIA capabilities.

Re: Paging HTML viewer
You don't have to know how tall each HTML portion is. You just need to know when to load the next page of data and that would be if your scroll position nearly reaches the bottom of ScrollPanel. Its pretty similar to what you can see here (see ShowMorePagerPanel.java): http://gwt.google.com/samples/Showcase/Showcase.html?locale=en#!CwCellList So you just need a ScrollPanel with a ScrollHandler attached that notifies you when to load/render the next page of log entries because the user has nearly scrolled to the end of the displayed widget. I have implemented a list some time ago (before cell widgets) that required fixed height list entries and only rendered the list entry widgets when they are actually visible to the user. So at any time during scrolling the DOM only contained that much elements needed to fill the visible area. Scrolled out items were removed from DOM while scrolled in items were attached constantly while scrolling. The math wasn't that complicated and it works pretty well but because of the constantly deleting and adding of DOM elements while scrolling we had some hiccups in older IE's when scrolling fast through the list. But we could easily scroll through thousands of list entries while only having ~40 DIVs (depending on list height and fixed list entry height) to represent them. Although it worked I think I wouldn't do it again that way unless you have some memory constraints (mobile devices) and don't want to have that many invisible DOM elements laying around (on the other hand constantly updating the DOM can cost more battery power on mobile devices). Having a ScrollHandler that notifies you when reaching the end of the list is a simpler solution. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to let this Map be transferred by GWT-RPC correctly?
I guess the reason is that you return a raw Map. A raw Map means Map?
extends Object, ? extends Object and GWT now has to check all possible sub
classes of Object (= all classes) to see if they can be safely serialized.
GWT then finds the serializable class PathImpl on the classpath and
complaints about a final List variable inside that class (GWT-RPC can't
serialize final fields yet I think).
Also because you have used Map/List GWT has to generate JavaScript code to
support serializing all implementation classes of Map/List even if you
never use them.
When you use GWT-RPC there is a rule very different from what you know from
Java: Be as explicit as possible *(as long as it makes sense)* while
defining your GWT-RPC methods. So instead of a raw Map use a parametrized
HashMap or TreeMap. In your example its probably best to create a DTO
class, e.g.
class MyResult implements Serializable {
ArrayListPost posts;
TreeMapInteger, User users;
}
Now GWT will only validate MyResult, ArrayList, TreeMap, Integer, Post and
User instead of every class on the classpath and the warning should
disappear. Also only JS serialization code for ArrayList and TreeMap will
be generated instead of code for all List and Map implementations. Being
explicit only counts on GWT-RPC, so for everything else in your app you
should use Map/List/Set.
If your app grows and you plan to have RPC methods with all kinds of
List/Map/Set implementations then you can of course use the Map/List/Set
interface (because then you need serialization code for every
implementation anyways) but you should still parametrize them.

querying binary data
There is service that gets and responses binary data and Java SWING client application that works with that service. I wish to replace Java SWING with GWT app. Is there GWT API to query binary data? It is unlikely to encode binary data on server. I need that to work at least on WebKit as app must work on iOS.

When I try to load the module, I got the following error:

Is there something wrong what I did? or missed?
I will appreciate any ideas on this problem. Thanks.

Re: window scrolls to top afte closing PaopupPanel
Hi,
I use following code :
int left = eachHotel.getAbsoluteLeft();
int top = eachHotel.getAbsoluteTop();
final DialogBox dialog = new DialogBox(true, true);
dialog.getElement().getStyle().setHeight(Window.getClientHeight() - 255,
Unit.PX);
dialog.setPopupPosition(left, top);
$(dialog).as(Effects).fadeIn(100, new Function() {

I am setting the position relative to some object(eachhotel).
Once the dialog closes, the Window scrolls to top.

Re: GWT Multi-Module Server Classpath Problem
On Friday, 10 August, 2012 at 10:34 AM, Thomas Broyer wrote: Are the JARs exported by the common Eclipse project? They aren't -- both M2E or eclipse:eclipse handles transitive dependencies by adding the JARs to the class path of the 'child' project, so you don't need the 'parent' to export, AFAICS. Over the weekend, I discovered that the child project was showing up as a WST project; I haven't done much with WST so I don't know what its builders and natures do, and the Deployment Assembly seemed like it might be getting in the way. When I took those natures and builders out of my .project so that it more closely matched the single-project version I'd been using previously the SLF4J errors went away, but only because my problems got more severe. Now a launch configuration (even a completely new one) starts up without errors or warnings, but then 404s on all requests, including for the project's simple HTML page, e.g.: [WARN] 404 - GET /Project.html?gwt.codesvr=127.0.0.1:9997 (127.0.0.1) 1395 bytes I still don't feel like I have much of a sense of why this would be happening and in what way this project is different from other GWT projects that I can still launch from Eclipse, which is frustrating. The multi-project nature of this doesn't seem to explain all my problems (although perhaps it does). The same project still launches successfully from a mvn gwt:run, so it's not entirely a lost cause, but I'd prefer the Google Plugin for Eclipse to work with it too. - Geoffrey-- Geoffrey Wiseman http://www.geoffreywiseman.ca/ -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
