A simple value picker like;

<xe:valuePicker id="valuePicker2" for="inputText1">

<xe:this.dataProvider>

<xe:simpleValuePicker valueList="${javascript:return ['a', 'b', 'c']}"></xe:simpleValuePicker>

</xe:this.dataProvider>

</xe:valuePicker>

generates the following exception:

java.lang.ClassCastException: java.util.Vector incompatible with java.lang.String

It works if you use #{...} but not with ${...}. On the source code, we can see the problem;

    @Override

    public void restoreState(FacesContext _context, Object _state) {

        Object _values[] = (Object[]) _state;

        super.restoreState(_context, _values[0]);

<strong>&nbsp; &nbsp; &nbsp; &nbsp; valueList = (String)_values[1];</strong></div>

&nbsp; &nbsp; &nbsp; &nbsp; valueListSeparator = (String)_values[2];

&nbsp; &nbsp; &nbsp; &nbsp; labelSeparator = (String)_values[3];

&nbsp; &nbsp; &nbsp; &nbsp; caseInsensitive = (Boolean)_values[4];

&nbsp; &nbsp; }

&nbsp;

There is a wrong casting.
