Description
I have this example:
import groovy.swing.* import javax.swing.* def swing = new SwingBuilder() def masterData = [en: ['Hello, World!', 'How are you?'], es: ['Hola Mundo!', "Como Esta?"], can: ['Foon Ying!', 'Lei Ho Ma?']] def detailModel = new DefaultListModel() swing.actions() { action(id: 'masterAction', name: 'masterAction', closure: {e-> def l = e.source if (!e.valueIsAdjusting) { def i = l.selectedValue detailModel.clear() masterData[i].each { detailModel.addElement(it) } } }) } swing.frame(title: 'My Frame', pack: true, visible: true, defaultCloseOperation: javax.swing.WindowConstants.EXIT_ON_CLOSE) { panel() { tableLayout() { tr { td { scrollPane() { list(valueChanged: masterAction.closure, visibleRowCount: 3, listData: masterData.collect {k, v -> k }) } } td { scrollPane() { list(visibleRowCount: 3, model: detailModel) } } } } } }
the code shown works fine when run under Groovy 1.6.4 via IntelliJ Maia EAP 10666. When run directly in 1.6.4’s GroovyConsole, it gives an error:
Exception thrown: Cannot cast object '[en, es, can]' with class 'java.util.ArrayList' to class 'java.util.Vector' org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '[en, es, can]' with class 'java.util.ArrayList' to class 'java.util.Vector' at ConsoleScript0$_run_closure2_closure5_closure6_closure7_closure8_closure10. doCall(ConsoleScript0:31) at ConsoleScript0$_run_closure2_closure5_closure6_closure7_closure8_closure10. doCall(ConsoleScript0) at ConsoleScript0$_run_closure2_closure5_closure6_closure7_closure8. doCall(ConsoleScript0:30) at ConsoleScript0$_run_closure2_closure5_closure6_closure7_closure8. doCall(ConsoleScript0) at ConsoleScript0$_run_closure2_closure5_closure6_closure7. doCall(ConsoleScript0:29) at ConsoleScript0$_run_closure2_closure5_closure6_closure7. doCall(ConsoleScript0) at ConsoleScript0$_run_closure2_closure5_closure6.doCall(ConsoleScript0:28) at ConsoleScript0$_run_closure2_closure5_closure6.doCall(ConsoleScript0) at ConsoleScript0$_run_closure2_closure5.doCall(ConsoleScript0:27) at ConsoleScript0$_run_closure2_closure5.doCall(ConsoleScript0) at ConsoleScript0$_run_closure2.doCall(ConsoleScript0:26) at ConsoleScript0$_run_closure2.doCall(ConsoleScript0) at ConsoleScript0.run(ConsoleScript0:24)
The workaround is to use:
list(..., listData: masterData.collect {k, v -> k } as Object[])
This is probably more ‘correct’ according to the API, anyway.
Still, something feels ‘off’ here…why the different behaviors?
The IntelliJ run line is:
"C:\Program Files\Java\jdk1.6.0_16\bin\java" -Dgroovy.home=C:\DEVTOOLS\groovy-1.6.4 -Dgroovy.starter.conf=C:\DEVTOOLS\groovy-1.6.4\conf\groovy-starter.conf "-Dtools.jar=C:\Program Files\Java\jdk1.6.0_16\lib\tools.jar" -Didea.launcher.port=7532 "-Didea.launcher.bin.path=C:\Program Files (x86)\JetBrains\IntelliJ IDEA 10666\bin" -Dfile.encoding=windows-1252 -classpath "C:\DEVTOOLS\groovy-1.6.4\lib\groovy-1.6.4.jar; C:\Program Files (x86)\JetBrains\IntelliJ IDEA 10666\lib\idea_rt.jar" com.intellij.rt.execution.application.AppMain org.codehaus.groovy.tools.GroovyStarter --conf C:\DEVTOOLS\groovy-1.6.4\conf\groovy-starter.conf --classpath C:\DEVELOPMENT\CascadingLists\out\production\CascadingLists --main groovy.ui.GroovyMain C:\DEVELOPMENT\CascadingLists\src\CascadingLists.groovy
Java is:
C:\Windows\System32>java -version java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
This is IntelliJ Maia EAP #10666.
This is 64-bit Win7 RC.
Same issue is seen with 1.7-beta1.
Execution is like:
C:\DEVTOOLS\groovy-1.7-beta-1\bin>set CLASSPATH= C:\DEVTOOLS\groovy-1.7-beta-1\bin>set GROOVY_HOME=C:\DEVTOOLS\groovy-1.7-beta-1 C:\DEVTOOLS\groovy-1.7-beta-1\bin>groovyconsole.bat
