-----------------------------
Re openning
issue reproduced
topics definition (other topics similar):

inside the Transformer, I am doing
{{}}
{code:java}
void process(MyItem myItem){
KeyValueStore<String, SomeOtherItem> store =
context.getStateStore("storeName"); //fails here
}{code}
{{{}{}}}the supplier:
(spring bean prototype)
{{}}
{code:java}
private final MYService myServiceBean;
@Override
public void init(ProcessorContext context) {
myServiceBean.setContext(context);
}
@Override
public KeyValue<String, MyItem> transform(String key, MyItem myItem) {
myServiceBean.process(myItem);
}{code}
