I am trying to get the hang of griffon/grails/groovy for a project.

I get this error at compile time from my Test1Controller.groovy file:

[griffonc] /home/ironmantis7x/griffon_projects/test1/griffon-app/controllers/test1/Test1Controller.groovy: 14: unable to resolve class Threading ,  unable to find class for annotation
 [griffonc]  @ line 14, column 5.

Compilation error: Compilation Failed

This is my controller file:

package test1

import griffon.util.GriffonNameUtils as GNU

class Test1Controller {

    def model

    def clear = {
            model.griffonClass.propertyNames.each { name -> model[name] = ''
            }
    }

    @Threading(Threading.Policy.SKIP)
    def submit = {
            java.swing.JoptionPane.showMessageDialog(
            app.windowManager.windows.find{it.focused}, 
            model.griffonClass.propertyNames.collect([]) {
                     name -> "${GNU.getNaturalName(name)} = ${model[name]}"
            }.join('n')
            )
    }

}

Like I said I am new to griffon/grails/groovy - can someone help me understand what I seem to be missing?

Thanks!

I made the change suggested below and now I get this error when I run: griffon run-webstart -clean:

net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize application.

How do I sign the app to get past this error?

This is my configuration running griffon -version:

Application signing should happen by default. When run-webapp is invoked the signature is taken from griffon-app/conf/BuildConfig.groovy. This signature is a self-signed one when running in development. For example, the following output is form running webstart mode in development without any configuration changes

Couldn't fail to notice net.sourceforge.jnlp.LaunchException in the stack trace you posted. Are you using a different JNLP launcher other from the one provided by the JDK? Also, what's the output of running griffon -version? Mine is

As you are using threading annotations you should import griffon.transform.Threading on your controller. 

package test1

import griffon.util.GriffonNameUtils as GNU
import griffon.transform.Threading 

class Test1Controller {

    def model

    def clear = {
            model.griffonClass.propertyNames.each { name -> model[name] = ''
            }
    }

    @Threading(Threading.Policy.SKIP)
    def submit = {
            java.swing.JoptionPane.showMessageDialog(
            app.windowManager.windows.find{it.focused}, 
            model.griffonClass.propertyNames.collect([]) {
                     name -> "${GNU.getNaturalName(name)} = ${model[name]}"
            }.join('n')
            )
    }

}
