${flowScope.lastViewStateId} is not working in transition - Spring Web Flow RC1

[swfstarter]

Hi

We are using Spring web flow RC1 version. I wanted to implement application back button functionality. I am trying to use ${flowScope.lastViewStateId} after coding Listener class. But unfortunately, it keeps throwing SAXParseException:Attribute ${flowScope.lastViewStateId} IDREF must be a name.

It would be greatly appreciated if someone using RC1 version has some kind of workaround for this problem as we CANNOT change the version of Spring Web flow at this juncture.

Thanks

I don't think SWF RC1 supports dynamic transition target state resolution as you're trying to do here. So if you really can't upgrade to SWF 1.0 final I would suggest you dive into the RC1 source code and modify that add this feature. Then use your custom RC1 version in your app.
