Re: Safari 5 - (RangeError): Maximum call stack size exceeded
There is an Issue 4393 about this bug.
I've applyed dunhamsteve's patch and also in all binarySearch()
functions in Arrays.java and Collections.java changed:
- final int mid = low + ((high - low) 1)
+ final int length = high - low;
+ final int half = length 1;
+ final int mid = low + half;
and just repacked gwt-user.jar replacing those files.
This worked for me.

So did you end up rebuilding the GWT itself? Where do I start to apply

This is occurring for us in the Arrays.mergeSort() code. A reduced
testcase (which looks like the binarySearch code) is in the webkit bug
tracking system at:
https://bugs.webkit.org/show_bug.cgi?id=40355
It appears that in some complex expressions the right shift operator
is not evaluating correctly. Assigning the result of the right shift
to a temporary variable and then using it appears to make the problem
go away.
As a temporary fix, we're patching Arrays.java:mergeSort() to assign
the result of the right shift to a temporary variable before using it.
If you're using binary search you'd need to patch those functions as
well. It's a bit of a hack, but it seems to work. I've included our
patch below, in case it is helpful to someone.

FormPanel: why it extends SimplePanel?
Is there a good reason for FormPanel to extend SimplePanel and not some other panel (like HTMLPanel)? The problem with SimplePanel is the restriction to only one child, while most forms contain much more fields. So one shoud use some other Panel whithin the Form and this leads to unnecessary markup. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: FormPanel: why it extends SimplePanel?
Yes, but whith this solution I have formdiv/div/form in resulting page, and the inner div is superfluous. Which is the whole point of my question. ) On 9 ноя, 23:39, Jeff Schwartz jefftschwa...@gmail.com wrote: Add an HtmlPanel to it and then add your widgets to the HtmlPanel.

Module can't be loaded when host page has an element with id same as module name
When I have a div id=test.../div on the host page and have module rename-to=test in the module xml file, this module can't be loaded (especialy in IE), because bootstrap code from module.nocache.js tries to create an iframe with the same id as module name. Then on the maybeStartModule() it successfully gets the required element just to find out it's not an iframe and has not contentWindow property. I think this should be at least documented, or, better, fixed: id of the frame should be generated with the algorithm same as with css class names in UiBinder and/or somehow controlled. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

AutoBean with JSONP
Hi! I'm trying to use AutoBean framework to transfer data from server
to GWT App. GWT-RPC is not good for me, because i need to cache
responces.
So I'm trying to use JsonpRequestBuilder to fetch data and AutoBean
framework for encoding/decoding.
The simple (and not working) aproach is like this:
servlet's doGet() method ---
String json = AutoBeanCodex.encode(data).getPayload();
String callback = request.getParameter(callback);
PrintWriter out = response.getWriter();
try {
out.write(callback);
out.write(();
out.write(json);
out.write(););
} finally {
out.close();
}
--- client ---
JsonpRequestBuilder jrb; // = ...
jrb.requestString(url, new AsyncCallbackString(){
public void onSuccess(String result) {
AutoBeanDataType bean = AutoBeanCodex.decode(factory,
DataType.class, result);
DataType data = bean.as();
//
}
public void onFailure(Throwable caught) {
}
});
-
Unfortunately, this does not work, because returned data is not
actualy a String, it's a JavaScript object.
I've tried to escape json on the server to make it String:
---
out.write(callback);
out.write((\);
out.write(escape(json));
out.write(\););
---
This works, but in my case it increases responce size from 700kb to
3Mb which is really not good.
Any ideas what to with this?

Re: AutoBean with JSONP
I've found a solution: it's possible to convert Object to String on
the client:
---
JsonpRequestBuilder jrb; // = ...
jrb.requestObject(url, new AsyncCallbackJavaScriptObject(){
public void onSuccess(String result) {
JSONObject jsObj = new JSONObject(result);
AutoBeandatatype bean = AutoBeanCodex.decode(factory,
DataType.class, jsObj.toString());
DataType data = bean.as();
//
}
public void onFailure(Throwable caught) {
}
});
-
But I don't know about performance: parsing this object 2 times on the
client may be slow.
May be there are some better solutions?

Integer and int are not equal... Especially if received via JSNI
I've spent a huge amount of time trying to find the source of one strange
bug in my app, so I want to share what I've found.
First I should say I'm using GWT 2.3 currently, so i don't know if the
described behavior changed in latest version.
My app is receiving some data from my server, displays it and after some
user actions send something from this data back to the server.
I’ve used standart GWT RPC for this data exchange and everything was fine.
Then we decided to receive that data via JSON requests and here my trubles
started: trying to send data back to the server (with the old GWT RPC
method) throwed the com.google.gwt.user.client.rpc.SerializationException:
undefined at Unknown.anonymous(Unknown Source).
Well, I’m not going to tell all the steps how I’ve found the problem, just
the result.
My data class looks like this:
public final class MyDataObj extends JavaScriptObject {
//… NoArgs constructor and other stuff
public final native Ineger getMyDataVal() /*-{ return this.myDataVal; }-*/;
}
I’ve used Integer and not int here because null value is perfectly valid
here and has its own meaning.
But in JSON this was a normal JavaScript integer or the absence of the
property.
It was fine. Just until GWT had to serialize this Integer for RPC. Or until
I’ve tried to use toString() or intValue() on it. That fails, since this
was not an Integer.

Re: Integer and int are not equal... Especially if received via JSNI
Yes, this manual boxing is what i did to solve this. I don't use DevMode because it's a bit difficult to configure my environment for it: i use JBoss as my app server and the app is deployed via .ear archive with some other modules it needs to work... I'm sure it's possible to configure somehow, just i didn't need it. :) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
