RE: Exceptions not showing up in Dev Mode Panel
That was it, thanks for the quick help. Adding $entry() around my callbacks

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.

RE: GWT and Firefox
I'm pretty sure that if you remove or comment out (with !-- comment -- since
this is xml) the following line in your .gwt.xml file, it will stop including
standard.css:
inherits name=com.google.gwt.user.theme.standard.Standard/
I'm not sure that this is really your problem though. Make sure your elements
have the class you want applied to them maybe?

it seems to pick up my new one and then revert back to the default

Do I need to exclude the standard.css in some way? If so how do I do
that? Manually? or is that going to be a post operation for the ANT

OK, so that partially answers the question, at least now I can see
that my overiden css elements are being ignored for the standard.css
ones.
So, question - does this mean that I have to rename mine and then use
the SetStyle method to get this working?
.gwt-StackPanel {
}
.gwt-StackPanelItem gwt-StackPanelItem-first{
}
.gwt-StackPanel .gwt-StackPanelItem {

RE: Problem with javascript accessing Java fct.
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. -Original Message- From: Google-Web-Toolkit@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mogoye Sent: Friday, October 10, 2008 10:54 To: Google Web Toolkit Subject: Re: Problem with javascript accessing Java fct.

RE: Warning about using float fields with RPC (shocking bug)
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 -Original Message- From: Google-Web-Toolkit@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Alex Epshteyn Sent: Wednesday, September 17, 2008 20:32 To: Google Web Toolkit Subject: Warning about using float fields with RPC (shocking bug) Amazing but true: only a hanful of all possible float values will be serialized correctly on the server end of GWT RPC.

I also can't use a solution that uses flash (IE support however, is not important). The solution I'm currently considering is to write a bunch of JavaScript Overlay classes for use with flot (http://code.google.com/p/flot/ ). As far as I can tell, gchart (http://code.google.com/p/gchart/) is the only native GWT graphing solution, but has no events support. I also looked into the dojox charting library, but flot seems to have better events support (particularly the ability to click on any point in the graph and get an event with the graph coordinates for the point clicked). Are there any projects out there that I've missed? I'd really like a native GWT solution, if possible.
