I'm using time picker as follows
this.valueTimeText = new Picker();
this.valueTimeText.setType(Display.PICKER_TYPE_TIME);
this.valueTimeText.setDate(null);
it displays native iOS picker and when I change the value I hit OK. The value is overtaken to the destination field but picker remains visible. It does not react on Cancel button and when I hit OK again application freezes with white screen, see attachment.
What should be wrong with this component. (with light weight version it works ok)
