hi, simply binding it does not work ?!?

public Class<? extends IFoldingRegionProvider> bindIFoldingRegionProvider() {
return StatemachineFoldingRegionProvider.class;
}

there seems to be a missunderstanding.

you don need to "find" a bind method. these are there only for some extension points
you can also add other

bind / configure and provide methods if there is none (see also https://www.eclipse.org/Xtext/documentation/302_configuration.html#dependency-injection)

But I have other question: How to save the folding state ?
After I reopen my code in xtext editor, the folding state disappear and I have to refold my code.
Thanks!

No, this is something you would have to implement yourself. Nothing in Eclipse directly supports such a thing. I have implemented such a thing for a customer... This claims to support such a thing:
