Are you using any JSNI that gets called directly from the browser?  Ie,
anything like obj.callback = function() {...};?  If so, you have to wrap any
entry points from the browser into GWT code with $entry, so that would look
like obj.callback = $entry(function() {...});

 

Note that it could be in library code you are using rather than something
you have written -- I don't have a good suggestion for tracking it down if
it isn't something you have written.

The project I have definitely worked when I was on 32bit.  And when I
created a new project it's giving the same error.

It's very frustrating.

I suspect a number of things "maybe" causing the problem

a) My app is not picking up the css file from the Module xml file.
b) It could be because my app has mixed Upper and Lower case chars in
it BDFTReportManager
c) Something to do with a missing inherits flag in the module file,
mine is a very simple proof of concept app at this stage and has no
RPC stuff in it, so I can't see why
d) I've tried dynamically loading the css file in the HTML file with a

e) I'm using a StackedPanel and TabPanel and these are the 2 where the
standard css settigns are not working and they just default back to

f) I've tried to ensure that i am using the SetStyle method to force

RE: FixedWidthgrid.autoFitColumnWidth no longer in the 9/4 drop

2008-10-10 Thread Perelman Nathan (Nathan) 

I got around this issue by creating a ScrollTable a different way from
GWT. Where the incubator ScrollTable (current, haven't looked at gen2),
uses a separate table for header, body, and footer, if you just use the
HTML thead, tbody, and tfoot elements, you can easily get autofit. Then
you can scroll just the body by giving tbody a set height in pixels and
setting its css style to overflow-y: auto. (Note that this doesn't work
in Firefox 1.0, so won't work in hosted mode on Linux.)

Hi, I just downloaded the latest gwt-incubator drop. The ScrollTable
works nicely! The problem though is that, when i create a table, each
column is evenly spaced by default. I actually want the columns to
"autofit" the contents just like the default behavior in Grid.

I saw the autoFitcolumnWidth method in FixedWidthGrid in previous drop
but not in the latest. There must be a reason for doing so.. either
too expensive or buggy. Still, is there  a way to allow contents auto
fit columns when first render a FixedWidthGrid?

Thanks,

RE: Problem with javascript accessing Java fct.

2008-10-10 Thread Perelman Nathan (Nathan) 

Actually, now that I think about it, I'm pretty sure that the code in
onModuleLoad doesn't get run until after the page is fully loaded. So
you can't have static JavaScript in your HTML that runs right away call
functions exported from Java that aren't there until after the page
loads. You could use more JSNI code to call a start function in
JavaScript from onModuleLoad after you call exportStaticMethod. I
believe that that would work.

I'm trying to call a Java method form a part of Javascript code.
I've read Accessing Java Methods and Fields from JavaScript and I
think I've reproduced something equivalent but it does not work.

Here is my HTML page :


  


var abcd = getJavaValue();


  
  
  


Here is the java code :
package com.eloquant.test.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.RootPanel;

public class Test implements EntryPoint {

public void onModuleLoad() {

exportStaticMethod();

RootPanel.get().add(new HTML ("abcd =" + getAbcd()));
}

public static int getValue() {
return 1;
};

public static native void exportStaticMethod() /*-{
   $wnd.getJavaValue = @com.eloquant.test.client.Test::getValue();
}-*/;

public native int getAbcd () /*-{
return $wnd.abcd;
}-*/;
}


When I run the app I get the following error :
com.google.gwt.dev.shell.HostedModeException: Expected primitive type
int; actual value was undefined
at com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:51)
at
com.google.gwt.dev.shell.ModuleSpace.invokeNativeInt(ModuleSpace.java:
193)...


If I replace in the HTML
var abcd = getJavaValue();
By
var abcd = 5;

I've got a correct display, so Java calling Javascript is Ok, but I
don't understand what's wrong with javascript calling java.

Does any one have some ideas ?
Thanks for reading

RE: Warning about using float fields with RPC (shocking bug)

2008-09-18 Thread Perelman Nathan (Nathan) 

I doubt that this will be resolved since all numbers in JavaScript are
treated as doubles. I'm not really sure what the correct translation of
floats in client side Java code should be, but just treating them as
doubles seems like a reasonable solution.

Also, the serializer has no way of knowing what precision you require on
your values. Note that of your example values, the only one precisely
representable in base 2 is 28.5. All others just happen to be rounded
back to representations with a single digit after the decimal point in
the decimal -> float -> decimal conversion, but not in the decimal ->
float -> double -> decimal conversion.

For example:
28.4 = 0x1C.66 (6 repeating, cut to 32 bits) =
28.3997615814208984375

Amazing but true: only a hanful of all possible float values will be
serialized correctly on the server end of GWT RPC.

Examples:

28.4 => 28.39618530273
28.5 => 28.5
28.6 => 28.60381469727
28.7 => 28.70762939453
28.9 => 28.89618530273

Fortunately this should be easy to fix.

I did chat component as HTML inside ScrollPanel and client side
receive message from server and appends it on the end of HTML and next

contains more rows than about 2000. After this one more message cause

In gmail chat this problem not appears, why? :)

2. HTML.setHTML(stringbuilder.tostring) (HTML is as ScrollPanel's

3. ScrollPanel.scrollToBottom
