migrating to 3.0.1: lift:Msgs class not found

[Boris Chazalet]

Hi everyone,

I am in the process of migrating a lift app to lift 3.0.1 and I am currently stuck on a view that doesn't want to render. I get the message below: 

Error processing snippet: lift:Msgs 
Reason: Class Not Found 
XML causing this error: 

          <lift:lift:Msgs showAll="true"><div class="row span24">
      <lift:error_class>alert alert-error alert-block</lift:error_class>
      <lift:warning_class>alert alert-success alert-block</lift:warning_class>
      <lift:notice_class>alert alert-info alert-block</lift:notice_class>
    </div></lift:lift:Msgs>
        

note: this error is displayed in the browser because your application is running in "development" or "test" mode.If you set the system property run.mode=production, this error will not be displayed, but there will be errors in the output logs.

What am I missing? Is it the Msgs class that is not found? Has it changed name/package?

Thanks a lot,

Boris

Not sure why this worked before, but that should probably be `lift:Msgs`, not `lift:lift:Msgs`.

See if that fixes it and if not we'll take a deeper look.

Thanks,

Thanks for your swift reply Antonio.

The 'lift:lift:Msgs' is what I see rendered, but the original html from the template is :

<div class="row span24" data-lift="lift:Msgs?showAll=true">

      <lift:error_class>alert alert-error alert-block</lift:error_class>
      <lift:warning_class>alert alert-success alert-block</lift:warning_class>
      <lift:notice_class>alert alert-info alert-block</lift:notice_class>
    </div>

Thanks to your hint, I have changed data-lift="lift:Msgs?showAll=true" to data-lift="Msgs?showAll=true" and it looks like it has fixed it.

I have got that pattern, e.g. data-lift="lift:..." in other places in the application I am migrating: am I supposed to remove the lift prefix everywhere then?

Yes, definitely. I'm actually not sure why that used to work to begin with, but

the `data-lift` prefix replaces the `lift:` prefix that you would use if you were using

a class instead.

Thanks,
