Description

The .each method and the for (x in y) methods sometimes provide the colelction as the iteration instead of teh iterated objects....

def loopBug(arrayList) {
println arrayList.class.name
println arrayList[0].class.name
def target
def swing = new groovy.swing.SwingBuilder()
def panel = swing.panel(alignmentX:0.0f, alignmentY:0.0f) {
boxLayout(axis: javax.swing.BoxLayout.X_AXIS)
hbox(alignmentX:0.0f, alignmentY:0.0f) {
vbox(alignmentX:0.0f, alignmentY:0.0f) {
target = checkBox(actionPerformed: { event -> println ""; println arrayList.class.name; for (e in arrayList) { println e.class.name; }} )
}
}
}
return target
}

def foo = new java.util.ArrayList()
foo.add("1")
foo.add("2")

def bar=loopBug(foo)
bar.doClick()

println ""

def loopBug2(arrayList) {
println arrayList.class.name
println arrayList[0].class.name
def target
def swing = new groovy.swing.SwingBuilder()
def panel = swing.panel(alignmentX:0.0f, alignmentY:0.0f) {
boxLayout(axis: javax.swing.BoxLayout.X_AXIS)
hbox(alignmentX:0.0f, alignmentY:0.0f) {
vbox(alignmentX:0.0f, alignmentY:0.0f) {
target = checkBox(actionPerformed: { event -> println ""; println arrayList.class.name; arrayList.each { println it.class.name; }} )
}
}
}
return target
}

def baz=loopBug2(foo)
baz.doClick()

I expect as output
"java.util.ArrayList
java.lang.String

java.util.ArrayList
java.lang.String

java.util.ArrayList
java.lang.String

java.util.ArrayList
java.lang.String"

but I get
"java.util.ArrayList
java.lang.String

java.util.ArrayList
java.util.ArrayList

java.util.ArrayList
java.lang.String

java.util.ArrayList
java.util.ArrayList"
