Re: Cross field validation on client
Hi, I was looking at the link http://www.gwtproject.org/doc/latest/DevGuideRequestFactory.html#validation , and it's not clear when the validation is executed. it seams it is executed each time data is sent to the server!!???. If it's the case, this could be a performance problem since we might have some complex validation processes that we want to execute only when we call some service methods (in a perfect world we would be able to decide on the client or server side if we want to execute a validation or skip it). this is really an issue because RequestFactory is thought as a rigid architecture : the user entered data can be reused only if the validation failed (otherwise the EntityProxy becomes frozen, and there's no easy way to duplicate an EntityProxy). So the best way to check a precondition constraint is in the validation process. The issue is that you have the choice between two scenarios: - You can do your checks in a specific service method, throw an exception and handle that in the onFailure() client side method. But!!! you cannot reuse the EntityProxy anymore since it's frozen - You can do your checks in the validation phase, so you can keep your EntityProxy reuasable, But!!! the validation is made each time you send data to the server (which can be a hard resource consumption issue) So the question is: is there a way to controle whether the server side validation process has to be made? (a per service method configuration or a runtime check switch)?

The idea is that you only validate those things that MUST be validated (and for that, you just put them in the default group, and other constraints in other groups; or you put them in a specific group and you use a ServiceLayerDecorator with an overridden validate() method to validate only that specific group). this is really an issue because RequestFactory is thought as a rigid architecture : the user entered data can be reused only if the validation failed (otherwise the EntityProxy becomes frozen, and there's no easy way to duplicate an EntityProxy).

(a per service method configuration or a runtime check switch)? I'm sure you can come up with clever tricks to pass some value down to a ServiceLayerDecorator's validate() method (e.g. through a request header, or appending data to the payload and stripping it in a servlet filter). I'm rather supportive of RF but it doesn't fit everyone's use-case (well, using only ValueProxies makes it a good replacement for GWT-RPC with an added batching feature, at the expense of bigger payloads but without the hassle of serialization policies). Wrt validation, RF works best if you restrict validation to per field (value ranges, patterns, etc.) or otherwise fast checks, and allow invalid data (wrt. other (business) constraint violations) to be persisted, along with a valid/invalid flag of some sort. Then depending on the valid/invalid flag you can decide whether some actions on the persisted data are possible or not. Actually, that's the approach that best fits the web, because you don't want to get in the way of the user and risk all his work to be lost (browser crash, broken connectivity, etc.): when I tell you to save, just save, when I tell you to act, feel free to refuse if the saved data is wrong. It generally requires totally rethinking the way you work with data and the way you store it, so it might only be possible in greenfield projects with enough budget and sufficiently skilled architects/developers. The alternative is to flush data (and edit()) into your proxies only when needed; that way you can just flush again in newly-edit()ed proxies should an error happen (if you use the Editor framework, that means *not* using the RequestFactoryEditorDriver; you could use edit on write proxies that read from frozen RF proxies and only edit() and write into RF proxies on flush; or you could copy data from the RF proxies to view model objects, and then edit the RF proxies and copy back again just before fire()ing the request) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Generation of permutations
I think the best practice is to decide which locale is your primary locale and: - define it as the fallback locale, and - use non-suffixed properties file for that locale and accept that a permutation for the default locale might be generated (should be the case as soon as you use locale-sensitive number or date formatting, if you only have messages then the default and your primary locale would possibly generate the same code and thus a single permutation). But using set-property name=locale value=de,en / (i.e. your supported locales minus default) should work I believe (John, who's the maintainer for the I18N stuff, said somewhere in the issue tracker that he wouldn't recommend it as it could break things in unpredictable ways, so I'd say if generating an extra permutation is really a problem for you, try removing the default locale and see if that works for you) On Friday, August 15, 2014 11:40:00 AM UTC+2, Developer wrote: After adding set-property name=locale value=de_DE,en_US / I'm getting just two permutations - great!

Re: GWT and BV/javax.validation 1.1
I had to upgrade to JPA 2.1 today to be able to use this feature: http://dreamand.me/java/java-jee7-jpa-stored-procedure-example/ It also required upgrading Hibernate.

Re: CellTable with optimal page size
I had the same request and went for the easy quick and dirty trick, ie
override the onresize method.
@Override public void onResize() { super.onResize(); if(dataProvider.getList
().isEmpty() || !dataGrid.isVisible() || (dataGrid.getVisibleItems().size()
== 0)) { return; } try { int pageStart = pager.getPageStart(); int rowHeight
= dataGrid.getRowElement(0).getOffsetHeight(); // TODO - find a way to
calculate the visible part of the rows panel int height = dataGrid.
getOffsetHeight() - 30; //((HeaderPanel)
(dataGrid.asWidget())).getHeaderWidget().getOffsetHeight(); pager.
setPageSize(Math.max(1, (int) Math.floor((double) height / rowHeight)));
pager.setPageStart(pageStart); } catch(Exception e) { } }
As you can see in the code, I have not found a reliable way to get the
header's size, and fixed it to 30px, there is always a little too much at
the bottom because of that + the fact that you need an integer number of
lines (so you will never have it fitting perfectly anyway), but at least it
gets adjusted to the right number of lines automatically.

JsInterop advance?
Community:
I'm playing with JsInterop , and I have two questions:
1) Are you planning to try the static methods of JS objects, such as
Object, Promise, etc.?
2) How do when an instance is mapped to an existing Object, eg
Promise, has a constructor with parameters?
Currently to resolve this 1) I created the following class Factory: JS
https://github.com/workingflows/gwt-jscore/blob/master/src/main/java/com/workingflows/js/jscore/client/factory/JS.java
But the interfaces define a contract at the level instance of a class
or object, this way of doing things, I do not know if it is semantically
correct.
To solve 2) there are not many options:
Create a Factory that returns an instance of the object, because it
has no meaning, only to make the new, implement the interface, because the
compiler already does.
There is some progress in this?
I saw in one of the post a proposal to do something like this:
Promise Promise.Prototype p = new (new Function ., new Function
);
Where Promise, is the interface defined with prototype = Promise.
@JsType(isNative = true, prototype = Promise)
public interface Promise {
void then(Function f);
void cath(Function f);
}

Re: render a SVG graphic as bitmap?
Also wrote a bunch of map animations in SVG back in 2011. Used SMIL to markup the animations and movements of viewports. Worked out quite well in FF at the time, but IE was terrible. Chrome worked well, but there were a number of SMIL methods that Chrome either didn't implement or did so incorrectly. I suspect it has much improved by now, especially given that browser vendors started to care about SVG once *retina displays* came out. For great demos, check out http://svg-wow.org/. Note, when you use a world map with 1M+ points, it does render slower. Joe -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

There will be some static helpers provided from the SDK. I originally
started the JSNI 2.0 document but it is basically waiting for me to start
on Elemental 2.0 and accumulate more experience to turn it into something
more concrete.
2) How do when an instance is mapped to an existing Object, eg
Promise, has a constructor with parameters?
Actually I have new ideas on this derived from how some other APTs work.
I need to update the JsInterop doc but these are the options that I'm
thinking right now:
*Option 1 (works better for extending):*
@JsType(prototype = Promise)public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static class Prototype extends Protoype_Promise {
public Prototype(Function... functions) {
super(functions);
}
}
void then(Function f);
void cath(Function f);
}
*Option 2 (works better for general use):*
@JsType(prototype = Promise)public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static Promise create(Function... functions) {
return new Protoype_Promise(functions);
}
void then(Function f);
void cath(Function f);
}
*Of course one can do both:*
@JsType(prototype = Promise)public interface Promise {
public static class Prototype extends Protoype_Promise {
public Prototype(Function... functions) {
super(functions);
}
}
public static Promise create(Function... functions) {
return new Prototype(functions);

or object, this way of doing things, I do not know if it is semantically
correct.
To solve 2) there are not many options:
Create a Factory that returns an instance of the object, because it
has no meaning, only to make the new, implement the interface, because the
compiler already does.
There is some progress in this?
I saw in one of the post a proposal to do something like this:
Promise Promise.Prototype p = new (new Function ., new Function
);
Where Promise, is the interface defined with prototype = Promise.
@JsType(isNative = true, prototype = Promise)
public interface Promise {
void then(Function f);
void cath(Function f);
}

Re: [gwt-contrib] JsInterop Advance
Static methods on interfaces is a Java8 only feature, but I prefer it.
Since you can use Java8 with GWT even if you are running Java7 or below as
a JVM, and since these features are not for shared code, but for Web code,
I'm kinda leaning towards the idea of JSNI 2.0 requiring Java8. We should
have a debate about this in the community. We get several benefits:
1. Static methods on interfaces
2. Defender methods to implement JSNI fragments on JsTypes
3. APIs designed for Lambdas everywhere.
Here's a motivating usecase right now:
@JsType
interface SomeJsType {
void someMethod();
default void anotherMethod(int arg) {
js(this.doIt($0, must be present, arg);
}
}
That is, there are some cases in Js interfaces where default prototype
dispatch is not what you want, and you need wrapper code.
Another use case
@JsType
@IterateAsArray(getter = item, length=length)
interface NodeListT extends Element extends IterableT {
T item(int x);
int length();
default IteratorT iterator() {
return NodeListIterator(this);
}
}
for (T x : nodeList) { ... }
Are we ballsy enough to say GWT 3.0 = Java8 source level enforced for
client side code?

Community:
I'm playing with JsInterop , and I have two questions:
1) Are you planning to try the static methods of JS objects, such as

There will be some static helpers provided from the SDK. I originally
started the JSNI 2.0 document but it is basically waiting for me to start
on Elemental 2.0 and accumulate more experience to turn it into something
more concrete.
2) How do when an instance is mapped to an existing Object, eg
Promise, has a constructor with parameters?
Actually I have new ideas on this derived from how some other APTs work.
I need to update the JsInterop doc but these are the options that I'm
thinking right now:
*Option 1 (works better for extending):*
@JsType(prototype = Promise)public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static class Prototype extends Protoype_Promise {
public Prototype(Function... functions) {
super(functions);
}
}
void then(Function f);
void cath(Function f);
}
*Option 2 (works better for general use):*
@JsType(prototype = Promise)public interface Promise {
/* Protoype_Promise is an autogenerated package visible class */
public static Promise create(Function... functions) {
return new Protoype_Promise(functions);
}
void then(Function f);
void cath(Function f);
}
*Of course one can do both:*
@JsType(prototype = Promise)public interface Promise {

super(functions);
}
}
public static Promise create(Function... functions) {

}
void then(Function f);
void cath(Function f);

Re: [gwt-contrib] JsInterop Advance
It is not like a library forces Java8; as we are supplying our own java8
compatible compiler, I think we are flexible to force Java8.
If there is shared code and they want to keep java7 compatibility, then
they should avoid using java8 specific features.

Re: [gwt-contrib] JsInterop Advance
Are we ballsy enough to say GWT 3.0 = Java8 source level enforced for client side code? I hope so. I am pretty sure everyone who has given Java8 a try so far, even if it was just an example project, feels the pain when coming back to a GWT project. If Java8 gives more freedom and a cleaner API design for Elemental 2.0 then GWT 3.0 should require it. Thats why it will be called 3.0...going forward. But when doing so, SDM in GWT 2.7 must work well on any project size because people might not migrate that fast to GWT 3.0 (depending on how many breaking changes it will contain) -- J. -- You received this message because you are subscribed to the Google Groups GWT Contributors group.
