beta 3 compile error

[skhan]

I know you recommended waiting for beta 3 to be released before playing with the code but I wanted to get a head start on changing my existing code (we use a lot of Tree/Table Viewers).

I can't build it because of the compilation errors listed below:

I'm currently using JDK 1.5 and I assume you're using JDK 1.6 with a target of 1.5 because I remember Beta 1 being compiled in 1.6

It seems that there was a bug with the JDK 1.5 compiler and I think it may have something to do with this.

See:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=98379
and
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6302954

Thanks

That is correct, it is caused by a bug in 1.5 compiler.

But you can just use the 1.6 compiler in "1.5" mode and everything will be fine.
If you cannot use the 1.6 compiler you can always cast the method calls temporarily until Darrel fix them,

e.g. in Theme.java

public String getName() {
return get("name").toString();
}

can be temporarily rewritten to

public String getName() {
return ((Object)get("name")).toString();
}


Then everything compiles again.

[Grandiosa]

But you can just use the 1.6 compiler in "1.5" mode and everything will be fine.

Actually, the ExtGWT ant build file allready sets the ant target property to 1.5. I think you have to use an Ant version that supports JDK 1.6. I use Ant 1.7.0.

[skhan]

We're required to use JDK 1.5 and upgrading to 1.6 isn't an option for us.
I was just making Darrel aware of this problem before he releases Beta 3 on Monday.

So I rewrote this:

public String getName() {
return get("name").toString();
}


as this:


public String getName() {
return this.<Object>get("name").toString();
}


and once again all is right with the world.

[darrellmeyer]

You are adventurous to be working with beta3 :). I have changed the code :
public String getName() {
return this.<String>get("name");
}Let me know if that works for you.

[skhan]

You are adventurous to be working with beta3 :)
Not adventurous, just desperate. We're working with some tight deadlines here and there was no point in continuing to work with beta2 if everything I was using was going to be changed.

I checked out the SVN code this morning and there are still some compilation errors, same bug, same fix. They're at:

There's also an error at line 78 of com.extjs.gxt.samples.explorer.client.mvc.NavigationView

Addiionally, there was an error with your package structure.
The declared package com.extjs.gxt.ui.client.binder was actually in com.extjs.gxt.binder.

That brings up a question, do you build your code before committing, because this would have been caught.

Also what is the status of beta3, is it still going to be released today?

Sorry for pushing this, but like I mentioned we're under some tight deadlines and I've been told to make a call on Wednesday on whether or not we want to continue development with Ext-GWT.
I've convinced management that this is the last major restructuring of the API and everything should be smooth sailing after this but people are getting nervous.

Thanks

When will Beta3 be released? We are anxious as well...

I'm getting compile errors around the Binder classes:

[skhan]

If you read my post above http://extjs.com/forum/showthread.php?p=166778#post166778
you'll notice I mentioned it.

It's a simple fix, move the sources in package com.extjs.gxt.binder to com.extjs.gxt.ui.client.binder

[companioncabinet]

Thanks! That did the trick :) I also have this javadoc error but its not holding me up:

The binder package has been moved and beta3 is now in the trunk.

Ok, but FYI the javac 1.5 generic bug i still present:

[darrellmeyer]

The generic bug is now fixed. Let me know if you still have any issues. The javadoc message is just a warning since the impl classes are filtered.
