Echo3 Beta7 Released

tliebeck's picture

New and improved releases of Echo3 and the Extras component are available now. The big news in this release is the implementation of automatic WindowPane sizing: the component can now in many cases automatically determine its height based on the size of its content. The demonstration app has been updated to make extensive use of this feature. WindowPanes additionally now can be positioned from the bottom or right side of a region, and maximize and minimize events are supported for server-side applications. The beta7 version of the Extras library adds only minor bugfixes relative to beta6.

According to the bugtracker, we are quite close to the RC1 milestone. Please report any bugs you find in beta7 to ensure that RC1 can be of the highest possible quality.

The EchoStudio beta release has also been refreshed to include the beta7 versions of Echo3 and Extras (and an updated license key).

I take it this problem is

I take it this problem is occurring when you're editing a form, i.e., when you create a new form and open it, you're not seeing anything in the editor window?

Could you give me details on your configuration, e.g., Platform / OS, Java version, Eclipse version, etc?

Also, if you create a sample application, and run it, does it work or does it also display a blank screen in the browser when run?

One more question...are you

One more question...are you running the new Safari 4 beta by chance?

I have the same

I have the same problem. I'm running Eclipse on Windows XP.
When a Java form component is opened in Design mode at Eclipse startup it reports an IE web page error:

Line: 4557
Error: 'null' is null or not an object

When I start the MS Script Debugger, it points to the line
runnable.run()
in function "_execute" of "Core.Web.Scheduler"

And yes, I have the Safari 4 beta for Windows installed.

No, i'm only use Firefox

No, i'm only use Firefox 3.0.5 like default browser

Is there a chance to have

Is there a chance to have the Echo Studio Design view work with the beta 7?

Try downloading the latest

Try downloading the latest version of EchoStudio, i.e., beta 1.1:

http://www.nextapp.com/downloads/echostudio3/v3_0_0_beta1_1/EchoStudio.zip

That should already include beta7.

I've tried and it failed.

I've tried and it failed.
With a little debugging in the MS Script Editor I found the following. An error-page gets generated:

<html>
<head>
<title>Error 500 nextapp.echo.webcontainer.ClientConfiguration.setProperty(Ljava/lang/String;Ljava/lang/String;)V</title>
<BODY>
<h2>HTTP ERROR: 500 nextapp.echo.webcontainer.ClientConfiguration.setProperty(Ljava/lang/String;Ljava/lang/String;)V</h2>
RequestURI=/EP0/app<p><i><small><a href=\"http://jetty.mortbay.org\">Powered by Jetty://</a></small></i></p>
</body>
</html>

This error should be displayed by the following function:
fail: function(detail) {
var element = this.domainElement;
try {
this.dispose();
} finally {
if (this.configuration["StopError.URI"]) {
window.location.href = this.configuration["StopError.URI"];
} else {
this.displayError(element, this.configuration["StopError.Message"], detail, this.configuration["Action.Restart"], 
function() {
window.location.reload();
});
}
}
},

But the var element is null and thus the following functions fails with a NullPointerException:

displayError: function(parentElement, message, detail, actionText, actionFunction) {
...
parentElement.appendChild(div);
...

Not b7

All nextapp.com links to EchoStudio.zip are for b0, not b7.

I tried replacing the jars with those for echo3 but I run into the same problems reported elsewhere with form redraw in the eclipse environment (I run 3.4 but have the same problems when I reverted to 3.1 as a test).

Currently, EchoStudio 2.1 with Echo 2.1 is the only combo that works... I rather need echo3, can we get an update?

Is there any roadmap or

Is there any roadmap or timeline when the next echo version will be released?

beta8 is just around the

beta8 is just around the corner, assuming no critical bugs.

Latest nightly builds are representative of beta8.

Same problem

Hi,
I've downloaded the new beta8 version but when I open a Panel with EchoStudio I get the same error:

This application has been stopped due to an error.
<html><head>
<title>Error 500 nextapp.echo.webcontainer.ClientConfiguration.setProperty(Ljava/lang/String;Ljava/lang/String;)V</title>

Any solution?

Same problem with Eclipse 3.5

Hi,
I've the same problem too.
I use Eclipse 3.5, and Echo3 beta 8.
I downloaded the EchoStudio plugin version 3.0 beta 1.1 and tried to replace
all the echo lib (Echo3_App, Echo3_WebContainer)
and echo extra libs (Echo3_Extras_App, Echo3_Extras_DT, Echo3_Extras_WebContainer)
inside the plugin folder with the corresponding libs from beta 8 release.
The application works correctly in the browwser but the preview into plugin Eclipse doesn't work.
The error is

This application has been stopped due to an error.
