Re: PSA: starting unbundling dependencies from gwt-dev published to Maven Central, could break your build
Adding http://mvnrepository.com/artifact/org.ow2.asm/asm/5.0.3 it worked again. El diumenge 12 d’octubre de 2014 10:35:09 UTC+2, Thomas Broyer va escriure: Hi all, If you're using 2.7.0-SNAPSHOT, your build might start failing as of today as we started unbundling dependencies from gwt-dev as published to the Central Repository. java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor If you get this error, be sure to also update your gwt-maven-plugin to the latest 2.7.0-SNAPSHOT too. If that doesn't work, add gwt-dev or (better) gwt-codeserver as a project dependency (and report the problem to https://groups.google.com/d/forum/codehaus-mojo-gwt-maven-plugin-users). This is likely to become the preferred way to use GWT in the future, and the gwt-maven-plugin might stop automatically adding GWT deps to the classpath in gwt:compile or gwt:run in a future version (probably not 2.7 though): as we'll unbundle more dependencies from gwt-dev (and gwt-user), you might want to gain control over those dependencies (e.g. using a newer version of Guava, or ASM, etc.) and this is not possible with plugin dependencies as it's done today within the gwt-maven-plugin. Also noteworthy: that same change also turned com.google.gwt:gwt into a BOM (bill of material); that means that instead of including the version in all your GWT dependencies you can now declare com.google.gwt:gwt into your dependencyManagement section with scopeimport/scope. As a bonus, it should ensure transitive dependencies to GWT will all use the same version, so you'll have fewer risks of conflicts. I'll soon update the GWT samples, WebAppCreator templates and various archetypes to use those new best practices. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Java Generics in GWT-RPC
We are having a SerializationException error when sending a list of objects
using RPC and Java Generics.
I'm creating this widget to show the error:
public class TestT {
ListDataProviderT ldp = new ListDataProviderT();
public void setItems(ListT list){
for(T t :list){
ldp.getList().add(t);
}
}
public ListT getItems(){
return ldp.getList();
}
}
This is the code for creating the Test widget and passing a list of POJOs
(where ExporterFormKey is the POJO object)
ListExporterFormKey list = new ArrayListExporterFormKey();ExporterFormKey
key = new ExporterFormKey();
key.setKey(key1);
list.add(key);
TestExporterFormKey test = new TestExporterFormKey();
test.setItems(list);
At the end the next code throws a SerializationException:
service.sendList(test.getList(), new AsyncCallback...);
While the next one does fine:
service.sendList(list, new AsyncCallback...);
I found that doing the next code also works
ListExporterFormKey newList = new ArrayListExporterFormKey(test.getItems());

Object and wmode
Hi, I use a FlowPanel and the method getElement().setInnerHtml(String html) to use an activex object custom video player like this: String object = object ... param name=x value=y/ param name=z value = o ... /object. The activeX object is working nice but I need to use the wmode parameter in order to let a DIV to layout on top of the player. It seems that GWT deletes my param name=wmode value=transparent but keeps other params. Why?

Re: GWT Project Structure Frontend/Backend
Yes. We are already doing this. We started using RequestBuilder and Json (Des)Serialization but we ended up using plain RPC services as development is so much easier.

Re: CellTable with only div's?
That is true. We are avoiding Vertical/HorizontalPanel. In fact, our idea behind using CellList is for the ability of use float:left (overriding CellList.Style) in even and odd cell styles. We couldn't to this with elements in CellTable because they are TDs (float:left and td are not very good friends) By the way, CellList with cells in float:left is an excellent way to create an Image Gallery for hundreds of images. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Handling clicks on CellWidgets
I think i maybe found another bug:
if
@Override
public void render(Context context, MyValue data, SafeHtmlBuilder
sb) {
sb.appendHtmlConstant(button class=\gwt-Button\ testbutton);
}
Clicking to the button fires a click only on the button if using the
improved onBrowserEvent you give me in the former link.
But if using a table wrapper:
@Override
public void render(Context context, MyValue data, SafeHtmlBuilder
sb) {
sb.appendHtmlConstant(table);
sb.appendHtmlConstant(tr);
sb.appendHtmlConstant(td);
sb.appendHtmlConstant(button class=\gwt-Button\ testbutton);
sb.appendHtmlConstant(/td);
sb.appendHtmlConstant(/tr);
sb.appendHtmlConstant(/table);
}
Using chrome trace tool I can see that the click event is fired but
onBrowserEvent is no even called!
using wrapper tables is a must to layout cells while no uibinder is
supported.

Hi, Happy new year to all!
I have some questions regarding cellwidgets. In the showcase
http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellSampler
when clicking the cell which contains the button, it reacts not only
when pressing the button but also when clicking inside the cell but
outside the button.
First Question, can i avoid this behavior and only reacting to the
button press in a cell?
Seehttp://code.google.com/p/google-web-toolkit/issues/detail?id=5641
(for now, you'd have to use your own ButtonCell if you want the fixed
behavior)
Inspecting the code for this example and the sample from CellList i
see the following:
From the CellList example, each cell is a div with a single onclick.
div onclick= __idx=0 class=GEGGSC0BI
style=outline:none;tabletbodytr ... /tr/tbody/table/
div
From the CellSampler (which uses a cellTable) the onclick is not in
each cell but in each row.
tr onclick= class=GEGGSC0BEDtd class=GEGGSC0BDC GEGGSC0BFD
GEGGSC0BGCdiv style=outline:none;/div/td/tr
I tried to use a composite cell with two buttons in a celllist but as
there is only one handler per cell, clicking on any of the two buttons
(and also outside the buttons but inside the cell) reacts with the
same handler. I can't distinguish them.
Question 2. How can I distinguish clicks inside a cell when using a
cell list.
Try using ActionCell instead of ButtonCell
Question 3 Am I forced to use celltable with different cells for each
column.
You can use the same Cell for several columns. If you want columns though,
you have to use CellTable, of make your own Cell widget (not trivial)
Question 4 How do you managed to distinguish cellclicks if there is
only one handler per row in a celltable?
Cell widgets use event delegation, they register a single event listener
but then dispatch accordingly, depending on the exact element targetted by
the event (i.e. FieldUpdater for a given Column, onBrowserEvent and
ValueUpdater for a given Cell)
