Question

having a bit of a spanner moment. I need to convert a List to String Array:

List<String> selectedIndicie to String[] targetIndices;

The selectedIndicie list is pulled from a backing bean and I attempt to convert it to a String array like so:

setTargetIndices(initialiseBean.getSelectedIndicie().toArray(getTargetIndices())); 

But Java has a right old moan saying:

An error occurred performing resource injection on managed bean searchBean

As I said I am having a spanner moment on how else to convert the List of Strings to an array of String so any suggests would be lovely.

Cheers

Answer 1

List.toArray returns an array of Objects, which is likely to result in an exception when you execute setTargetIndices for this method would be accepting an array of String objects. The answer is to not convert the setter to accept an array of Object (for the JSF runtime might simply fail to recognize the setter as belonging to the targetIndices property), rather it is to invoke the setter with an array of Strings.
