json and array
I have a problem with JSON and Array of String :
public class Test {
private String[] arrayString = new String[] {"row1", "row2", "row3"};
public String[] getArrayString() {
return arrayString;
}
public void setArrayString(String[] arrayString) {
this.arrayString = arrayString;
}
public static void main(String[] args) {
System.out.println(JSON.containsKey(new BeanAdapter(new Test()),
"arrayString[0]"));
}
}
I get this error :
Exception in thread "main" java.lang.IllegalArgumentException: Property "0"
not found.
at org.apache.pivot.json.JSON.containsKey(JSON.java:244)
at Test.main(Poub.java:24)

sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)

at java.lang.reflect.Method.invoke(Method.java:597)
at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120)
If someone can help me.
Best regards

The JSON class only works with Pivot collections. However, if you want to use a JDK list, you can wrap it in a ListAdapter.

Are you using a Pivot list or a JDK list? With a Pivot list, the example code works fine for me.

JSONSerializer doesn't work with arrays - it only works with Lists (since lists can be dynamically sized, whereas arrays cannot). Try changing String[] to ArrayList<String> and it should work fine.
