Compiler error running ootb web_ui sample

Question

i'm trying to compile the ootb web_ui sample. (Using Generate Sample Content - Web Application (using the web_ui library)

I have updated to latest editor 0.0.0_r18915 and have run pub update but am getting

Internal error:

'http://127.0.0.1:3030/C:/Users/me/dart/WebApplication/web/packages/logging/logging.dart':   
Error: line 250 pos 24: wrong number of type arguments in type 'Comparable'
class Level implements Comparable<Level> {

                   ^

Anyone have any ideas?

Got the same problem here, and after some time, i've decided to pay attention at the stack trace... It says "Wrong number of type arguments in type 'Comparable'". Then, i just opened "logging.dart" and changed this:

class Level implements Comparable<Level> {

to this:

class Level implements Comparable {

Don't know if i did right, but worked fine for me. If someone knows the right way to do it, please, let us know ;)

I had this with the newest build as well. On a Macbook Pro 10.7 . Solution worked for me. – Stephen Cagle Feb 28 '13 at 06:20

Click Dart Editor (menu item) -> About Dart Editor.
Click the Download Update button.
After the update has downloaded, install/apply the update.
After the installation is complete, go to Tools (menu item) -> Pub Install.
Go to Tools (menu item) -> Pub Update.

After doing those five steps, I am able to compile the code.
