Editing list of child objects in CellTable
I am trying to set up a CellTable with a HasDataEditor and it appeared
to work up until I tried to create an ActionCell column that launches
a dialog to edit a list of child objects (ex. My main CellTable edits
Fields and my dialog should provide a way to add Attributes like
read-only, enabled, etc. to those Fields). This dialog also uses its
own CellTable (although I suppose I could use a simple ListEditor if
need be) but the CellTable never seems to get any information.
I think I am having problems understanding fundamentally how this
would be hooked up and so I am asking
1. How do others usually deal with a situation of modifying lists of
child objects from their CellTable? Do you use a popup or is there
some way to edit them in place that I am not aware of?
2. Does hooking a CellTable up to a HasDataEditor work at all? I saw
old posts from the beginning of 2011 that suggested it did not but
they referenced a bug in 2.2 that appears to be fixed now.
3. If the q1 is use a popup/dialog and q2 is true, then how would I
set it up that the ActionCell knows to hook up the proxy it receives
to an editor? I couldn't think of it and thus produced the following
which is obviously wrong (given the error I stated in the paragraph
above):
ActionCellAttributeListProxy presentsCell = new
ActionCellPresentsListProxy(Edit...,
new ActionCell.DelegateAttributeListProxy()
{
@Override
public void execute(AttributeListProxy alproxy)
{
// Setup a dialog
// Pass in the RequestContext
// Start the driver
// Launch the dialog
plproxy =
requestContext.create(AttributeListProxy.class);
AttributeListProxy attributeEditor = new
AttributeListEditor();
attributeEditor .setRequestContext(requestContext);
attributeEditor .edit(plproxy);
attributeEditor .center();
}
});

Re: Canvas, ImageData, and IE9
One thing to mention with this technique is that it is based on the non-negative winding rule. This means that for complex shapes that have paths that intersect internally it will depend on the order that you draw your paths (clockwise or counter-clockwise) whether points are considered inside the shape or not. Having said that, I have tried to create a fail case from the example at http://www.w3schools.com/html5/tryit.asp?filename=tryhtml5_canvas_ispointinpath but have not been successful so far so I'm not sure to what extent one should worry about it. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT Canvas ImageData requires multiple reads to get value
I am wondering if anyone else has encountered this and if so is it a
bug or simply a misunderstanding on my part of how Canvas's ImageData
works.
I am trying to implement a simple hit detection on my canvas where
each graphic in a list is drawn in a solid colour representing its
index in the list. As I go through the list, I check the Alpha value
at the current mouse coordinates to see if they hit the graphic just
drawn and if so I return that graphic as the one that was selected.
The problem I am getting is that after getting the ImageData from the
Canvas and calling imageData.getAlphaAt(0, 0) I always get 0. After a
bunch of testing I found that if I call it multiple times in a row (at
the same location) I will eventually get the correct value. My code is
like the following:
hitContext.clearRect(0, 0, CANVAS_WIDTH, CANVAS_HEIGHT);
ListSymbol graphics = listener.getSymbolList();
for (int i = graphics.size() - 1; i = 0; i--)
{
graphics.get(i).draw(hitContext, i);
ImageData imageData = hitContext.getImageData(x, y, 1, 1);
// The coordinates for getAlphaAt are those of the imageData
not the original canvas.
int alpha = imageData.getAlphaAt(0, 0);// first time this
method is run, this always returns 0. afterwards, returns expected
result
alpha = imageData.getAlpha(0, 0); // also returns 0
alpha = imageData.getAlpha(0,0); // returns
correct value
if (0 imageData.getAlphaAt(0, 0))
{
}
}
So is this a bug in GWT or is this call assumed to be asynchronous
(although not stated as such) and if so how should I be handling it?

Editor Dialog with CellList does not display DockLayoutPanel
Hello, I have UIBinder class that extends DialogBox and implements HasDataEditor using a CellList. I want to show the CellList on the left hand side of the DialogBox and an editor on the right-hand side for editing a selected item. However, when I try to put a DockLayoutPanel the screen does not render it or any widgets it contains (but it still takes up space if I specify width and height on the DockLayoutPanel). The strange thing is that after a lot of testing I can show the same dialog without the HasDataEditor attached to any POJO and the DockLayoutPanel will appear just fine. Does anyone know if there is an issue with Editor + DockLayoutPanel or CellList + DockLayoutPanel appearing in a DialogBox? (I can provide code if necessary this issue has been driving me crazy for a few days now). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Recreating the CellList Showcase example with Editors
Hi Thomas,
After much tinkering, I managed to get it to work but I have 2
questions:
1. It seems to work equally well with ValuePicker or with using the
actual SelectionModel (since I guess the former is just hiding the
implementation of the later) with the exception that either way it
will select multiple rows if my ValueProxy has the same values as
another ValueProxy in the list. I tried to use a KeyProvider that
looks at the hashCode but this has the same effect (which I guess
makes sense if the hash is based on the values?) So is there a way
to correct this behaviour without adding extraneous fields to my model
or adding a uniqifier to the string?
2. I am trying to generify my dialog that contains the cellList but
I have hit a snag because I require a RequestFactoryEditorDriver
interface to accompany the inner Editor. However, if I use the
following code I get an error like ... is assignable to Editor raw
type but a Parameterization is required.

Recreating the CellList Showcase example with Editors
Hello, I have a case for a dialog that operates very similar to the CellList example included in the Showcase. That is, I need to have the ability to add items to a list, select them, and display a form (within the same dialog) for the selected item. I was trying to set it up with an implementation combination of HasDataEditor and ValueAwareEditor but even if I get the value from the CellList's SelectionModel I don't get how I can set the values on an editor that is dynamically displayed. (I thought maybe of using another RequestFactoryEditorDriver on the inner editor but this doesn't seem to work...) Then during my searches I found some very small amount of information on ValuePicker. However, I cannot grasp from the code or sparse documentation whether ValuePicker (as the name implies) is made for picking an option out of a preset list (like selecting an enum value) or for getting the value from a dynamic list for use in a separate editor? Can anyone provide any clues as to whether ValuePicker is what I should be using or if there is some way to achieve the concept of a form displaying the value of item selected from a list? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

RequestFactoryEditorDriver returns empty array for getPaths
I was banging my head against the wall trying to figure out why my ListEditor is not displaying any objects from a ListLanguageProxy in my ConfigProxy. I then realized I wasn't using the .with command. So I set it up with the standard idiom: .with(view.editorDriver().getPaths()).fire(); But then found out that the getPaths() method is returning an empty array. Is this a known issue (unlikely) or have I set something up wrong (more likely). Here is a rough outline of my setup for this editor: * ConfigPresenter implements Presenter * ConfigView implements EditorConfigProxy and contains getter methods annotated with @Path * ConfigViewImpl implements ConfigView and contains the interface that extends RequestFactoryEditorDriverConfigProxy, ConfigView I thought maybe it wasn't working because I use using the simple version of Driver.initialize(editor) instead of Driver.initialize(RequestFactory, editor) but after changing it (granted I had to do it in a rather contrived way as trying to initialize the Driver from the Presenter like I was previously doing wouldn't work in this case) the getPaths() still returned an empty array. Is there a step that I am missing? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Edit an object in a List without a ListEditor
So if I understand correctly, ValueAwareEditor basically allows you to
muck with how the object obtains its values? I have tried to
implement this in 2.3 but now I am getting a problem with the Config
object not retaining the values set for the LanguageProxy. That is,
the returned ConfigProxy seems to have the values but once the code
calls to the Server side, the values have been reset to null.
In my code:
In ConfigViewImpl (which implements ConfigView which in turn
implements ValueAwareProxyConfigProxy):
pre
@Override
public void flush()
{
ListLanguageProxy languages = new ArrayListLanguageProxy();
// Not sure if this is the correct way to create an editable
ValueProxy
LanguageProxy lang =
requestFactory.configRequest().create(LanguageProxy.class);
lang.setString(language.getText());
lang.setDefault(true);
languages.add(lang);
proxy.setLanguageList(languages);
}
...
@Override
public void setValue(ConfigProxy value)
{
proxy = value;
}
/pre
Then in ConfigPresenter:
pre
public void save()
{
ConfigRequestContext context =
(ConfigRequestContext)view.getEditorDriver().flush();
// If I use this code, the values persist properly.
//LanguageProxy language = context.create(LanguageProxy.class);
//language.setString(FRA);
//editProxy.setLanguageList(new ArrayListLanguageProxy());
//editProxy.getLanguageList().add(language);
if (null == saveRequest)
{
saveRequest = context.save(editProxy);
}
view.setLocked(true);
// Up to this point, the editProxy contains an ArrayList with
the correct LanguageProxy
saveRequest.fire(new ReceiverVoid()
{
@Override
public void onSuccess(Void response)
{
view.setLocked(false);
view.close();
}
}
/pre
On the server side's Save code, my Config object still contains an
ArrayList with a Language object but the fields of the Language object
are all null. If I use the commented code which sets the values in the
Presenter then those values will persist to the server side
correctly. Is this an issue with the way I have setup my
ValueAwareEditor, how I created the LanguageProxy, or something else?

Edit an object in a List without a ListEditor
Is there a way to setup an editor so with a subeditor for one item within a list without having to setup a ListEditor? My example is: I have an ConfigProxy that contains a list of LanguageProxy's (which contain a language code and a boolean for whether it is the default language or not). When the user first starts up the program I need them to create their ConfigProxy before doing anything and along with that I want them to specify a default language. That means I want them to create 1 and only 1 LanguageProxy that will be flushed into the ListLanguageProxy in ConfigProxy. Because I want them to only create 1 instance, it seems like overkill to have to put in a ListEditor but I cannot think of a way to setup the Path annotations to point a simple editor to object within a List. Is this possible? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group. To post to this group, send email to google-web-toolkit@googlegroups.com.

Re: Edit an object in a List without a ListEditor
Hello Thomas, Thanks for the suggestion. I do not quite understand the user of ValueAwareEditor though.

Re: JAXB + GWT
There shouldn't be any problems. In my case, I had my JIBX stuff in a separate project that got included into my webapp so I had to provide a *.gwt.xml file in it's base folder and do an include in my main *.gwt.xml file but other than that everything just worked. I was working with RPC methods, passing my XML domain objects back and forth and converting them to XML on the server side without any gwt related problems. Now I should note that I had a little it of trouble with JIBX itself in terms of converting enums to XML but that isn't related to GWT and a benefit of JIBX is you can modify your java beans to your heart's content (as long as your mapping files reflect what needs to be converted) and I was able to solve any problems that way. Another thing to mention is that JIBX has relatively little in terms of validation in order to keep its conversion process light. But since it produces beans you could, in theory, use a jsr 303 implementation to do the validation annotations there (a bit of duplication from the XML schema but can't be helped at the moment). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: JAXB + GWT
Hi, If you are not totally tied to JAXB you may want to check out JIBX. I was successfully using the beans that it creates on both Server side and Client side. The way it marshals is by injecting information into the bytecode and this seems to allow GWT to still recognize the source of the beans as being the same as the compiled server object. I have since refactored to use RequestFactory so that this entire issue is moot but if you cannot then I highly recommend JIBX. - Mike -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Trouble with List Editors
Hello, I have a model that contains a List of Language objects (which just contain a string for the language code and boolean to denote default). I am trying to setup a List Editor like that shown in http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/dynatablerf/src/com/google/gwt/sample/dynatablerf/client/widgets/FavoritesWidget.java for that model (with the major change that I am using SimpleBeanEditorDriver instead of RequestFactoryEditorDriver). However, during the creation of the LanguageEditor from the LanguageListEditor.LanguageEditorSource's create method, it dies on the call to uiBinder.createAndBindUi. The error seems to refer to native javascript and I am unsure of how to debug it any further. Does anyone have suggestions of what is the problem or how I can track it down further? 22:09:04.490 [ERROR] [viewappdesigner] Failed to create an instance of 'vivid.client.widget.LanguageListEditor' via deferred binding com.google.gwt.core.client.JavaScriptException: (TypeError): __static[458906].call is not a function at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java: 237) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java: 132) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java: 561) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java: 269) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java: 91) at com.google.gwt.dom.client.DOMImpl.createElement(DOMImpl.java) at com.google.gwt.dom.client.Document$.createDivElement$ (Document.java:290) at com.google.gwt.user.client.ui.HTMLPanel.lt;initgt; (HTMLPanel.java:79) at vivid.client.widget.LanguageEditor_LanguageEditorUiBinderImpl.createAndBindUi(LanguageEditor_LanguageEditorUiBinderImpl.java: 13) at vivid.client.widget.LanguageEditor_LanguageEditorUiBinderImpl.createAndBindUi(LanguageEditor_LanguageEditorUiBinderImpl.java: 1) at vivid.client.widget.LanguageEditor.lt;initgt; (LanguageEditor.java:50) at vivid.client.widget.LanguageListEditor $LanguageEditorSource.create(LanguageListEditor.java:47) at vivid.client.widget.LanguageListEditor $LanguageEditorSource.create(LanguageListEditor.java:1) at com.google.gwt.editor.client.adapters.ListEditorWrapper.add(ListEditorWrapper.java: 50) at vivid.client.widget.LanguageListEditor.lt;initgt; (LanguageListEditor.java:76) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.google.gwt.dev.shell.ModuleSpace.rebindAndCreate(ModuleSpace.java: 465) at com.google.gwt.dev.shell.GWTBridgeImpl.create(GWTBridgeImpl.java:49) at com.google.gwt.core.client.GWT.create(GWT.java:98) at vivid.client.view.ApplicationDialogViewImpl_ApplicationDialogViewImplUiBinderImpl.createAndBindUi(ApplicationDialogViewImpl_ApplicationDialogViewImplUiBinderImpl.java: 26) at vivid.client.view.ApplicationDialogViewImpl_ApplicationDialogViewImplUiBinderImpl.createAndBindUi(ApplicationDialogViewImpl_ApplicationDialogViewImplUiBinderImpl.java: 1) at vivid.client.view.ApplicationDialogViewImpl.lt;initgt; (ApplicationDialogViewImpl.java:77) at vivid.client.ClientFactoryImpl.lt;clinitgt; (ClientFactoryImpl.java:57) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at com.google.gwt.dev.shell.ModuleSpace.loadClassFromSourceName(ModuleSpace.java: 654) at com.google.gwt.dev.shell.ModuleSpace.rebindAndCreate(ModuleSpace.java: 458) at com.google.gwt.dev.shell.GWTBridgeImpl.create(GWTBridgeImpl.java:49) at com.google.gwt.core.client.GWT.create(GWT.java:98) at vivid.client.ViewAppDesigner.onModuleLoad(ViewAppDesigner.java: 44) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java: 396) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java: 193) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java: 510) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java: 352) at java.lang.Thread.run(Unknown Source) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
