[kohlerfc]

Thanks for the info. I will check if this is the case. So I guess 
I don't need to worry about my own URL encoding then.

I am seeing this issue as well. Very painful. Two minutes to de-serialize

Re: Force update of rows when using asyncdataprovider

[Thomas Lefort]

OK, this seems to work for now. I added the following code to my 
asyncdataprovider class:

public void refresh() {
for(HasData display : this.getDataDisplays()) {
onRangeChanged(display);
}
}

It reloads data from teh server each time but it's not a big issue.

Force update of rows when using asyncdataprovider

[Thomas Lefort]

I am looking for advice.

I display potentially a large amount of data available on my server in a 
cell table using the asyncdataprovider.

I can edit the data items in the list or add new items to the list. My 
problem is what is the best way to update the list once I have created a 
new item or edited one? shall I create a refresh method that calls the 
onRnageChanged method to force a refresh?

Thanks,

Thomas

Re: Text of Suggestbox not seen in rendered code on some Browsers - strange?!

[tanteanni]

i just read the javadoc for getAttribute:

"...More exactly, this method will return the value of the given attribute, 
unless that attribute is not present, in which case the value of the 
property with the same name is returned..."

So all is fine and work as intended :-)

What should i say element.getText() returns "" and fails (this is used by

webdriver).

but thx for the hint with InputElement: but i can't find class/ or

GWT Compile in eclipse and running GWT compile via external run configuration give different results

[Paul]

GWT 2.4.0

I am trying to understand why when I right click my GWT project and perform 
a GWT compile in eclipse I get what I expect but when I setup the GWT 
compile process via the GWT Maven plugin or as an external run 
configuration I do not get what I expect. It looks like as if an entire 
permutation is not created.

So maybe my question is, how do I mimic the eclipse GWT compile process in 
eclipse via an external run configuration? This should then allow me to 
deduce what the issue is.

Currently I setup a java run configuration as follows =>

Project: my GWT project
Main class: com.google.gwt.dev.Compiler

arguments: my module

classpath (User Entries):
   my GWT project
   my GWT project maven dependencies container
   folder to source of my GWT project
   folder(s) to source of other GWT module projects

I run this and it compiles my project (7 permutations) yet when finished I 
only have 6.

If I run GWT compile built into eclipse against my GWT project then I get 
the 7 permutations as expected.

A bespoke GWT linker has been added to generate an artifact that contains 
information on the entire build. This should have no bearing on the issue 
but I mention it just in case.

Any ideas?

It shouldn't.
(except in IE because GWT simply calls getAttribute(name), and IE looks for 
the property in this case rather than the attribute: 
http://msdn.microsoft.com/en-us/library/ie/ms536429(v=vs.85).aspx )

Use element.getValue() instead (possibly casting first to an InputElement: 
element.cast().getValue()), or 
element.getPropertyString("value")

It's likely a bug with "modal" popups. As a rule of thumb, don't use 
"modal" popups. Instead, use the "glasspanel" of the popup to cover the 
rest of the app for the same net result, and without the bugs.

How to integrate the GWT command pattern with spring

[Saritha]

Hi All,

I have a project where I am using the GWT command pattern to implement the 
RPC. Here how i can integrate the Spring with GWT. Without Spring I am able 
to achieve the RPC. But here i need to use Spring Dependency Injection for 
GWT server side packages.

I am unable to find suitable sample or links to implement that. Can anyone 
please provide the links and samples which has this requirement.

Without command pattern, I am able to integrate spring with GWT by 
referring following links

http://technophiliac.wordpress.com/2008/08/24/giving-gwt-a-spring-in-its-step/

https://docs.google.com/document/pub?id=1USHYx9cB3B1s1zM4dlkzEZ759D3lEfavn_dDewvBkaA

Thanks, 

Saritha

In which context are you using that value?
History.newItem also does a bit of sanitization/encoding, and then your 
browser can decide whether it shows you the %-encoded text or not. Note 
however that History.newItem is supposed to work with any kind of value, so 
if you give it "%25" it's very likely (I haven't looked at the code for 
ages) it'll encode the "%" and thus give you "%2525".

Er, honestly, the difference in maintainability and readability between 
"JSONParser.parseStrict(jsonStr).isObject().getJavaScriptObject()" and 
"JsonUtils.safeEval(jsonStr)" leans to the latter. And because it's also 
slightly faster (does not create a JSONObject, does not check whether it's 
an object vs. an array vs. a number vs. a String, etc. to know whether to 
build a JSONObject, JSONArray, JSONNumber, etc.), there's absolutely no 
single reason not to prefer it.

+1.
Here you can balance readability vs. performance. AutoBeans are also usable 
on the server-side: I use the same AutoBean in both sides to pass 
information at "bootstrap" (host page is a JSP, using an AutoBean to output 
a var foo = {...}, and in the GWT code, with a bit of JSNI 
and a cast to JsoSplittable, I get the object as the same AutoBean 
interface).

But that was not the question here.

Re: Migrating a GWT AppEngine App to a Chrome offline app

[Vishal Singh]

Ashwin - I am still considering various options. You have a point with 
offline clearing of cache. I would think that with offline storage like *
IndexedDB*  would not be deleted if the user clear the cache. At least the 
user will be prompted if an application data is going to be cleared. I am 
not sure how it works.
My main point is I really do not want to invest in another technology for 
building a local app. I would want to use all the GWT code written so far. 
Also it should be easy to update chrome apps. This should simplify the 
distribution also.


Also I think I would have to use hybrid approach of storing data in cloud. 
But I have the challenge of security. I would may be need to encrypt data 
using a key which only resides locally. There are lot of unknowns and I 
would have to figure out.
