As the binding to <valueKey> to a Wonder ERPCategoryChart widget I had a
NSMutableArray<Integer> and the following error ensued:
- com.webobjects.foundation.NSMutableArray cannot be cast to java.lang.Number
java.lang.ClassCastException: com.webobjects.foundation.NSMutableArray cannot
be cast to java.lang.Number
at er.plot.ERPCategoryChart.createDataset(ERPCategoryChart.java:129)

at er.plot.ERPChart.otherTagString(ERPChart.java:268)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
I then added the line for the <valueKey> (but got error)
Integer[] xint = new Integer[]{0,1,2,3,4,5,6,7,8,9,10,11};
- [Ljava.lang.Integer; cannot be cast to java.lang.Number
java.lang.ClassCastException: [Ljava.lang.Integer; cannot be cast to
java.lang.Number
at er.plot.ERPCategoryChart.createDataset(ERPCategoryChart.java:129)
...
What does <Ljava] imply?
Am I missing something in the binding, my <item> array is a NSArray of inner
class objects:
public class BarChartItem { // inner class
public String[] xNameKey;
public String[] yNameKey;
public String nameKey;
public Number[] valueKey;
BarChartItem( String[] xNameKey, String[] yNameKey, String
nameKey, Number[] valueKey ) {
this.xNameKey = xNameKey;
this.yNameKey = yNameKey;
this.nameKey = nameKey;
this.valueKey = valueKey;
}
}
Bonus question: what does the <categoryKey> do?
