I think I ought to let you all know of my experiences today.
I have a pile (about 20) of use cases nost with some structured scenarios, ie a basic path and several alternate paths.
Firstly, when creating new alternate paths, you get a dialogue listing other alternate scenarios that you can use. Renaming and deleting these scenarios seems to be difficult for EA to accomplish, but that is not my main point, although it may have something to do with the problems I got today.
I decided that I didnt like the order that my Use Cases were sitting in the Project Browser, so I selected them and moved some of them up and down using those pretty green arrows. Then I regenerated my document using eaDocX. Imagine my surprise, when the document showed alternate scenarios from some use cases appearing in other use cases. I used the built in document generator and that too showed similar, but not the same, results.
Is there a problem with the model I ask myself? Too darn right there is. On the face of it, the scenarios look OK, but the pick lists for new alternat paths are wrong. And to confirm it all, I exported the XMI which shows categorically that there are scearios that dont show up in the model!!! There are orphans in there and they dont show up when you Validate or Integrity check the model.
XMI does have its uses however, I deleted the rogue scenarios and re-imported the XMI and all is hunky dory once more in the land of EA. At least I only had to delete extra stuff and not insert missing stuff.
I have registered a bug report, but it seems that you have to be precise about what you put in the model and dont mess about with it afterwards.
Its still a brilliant tool and save loads of effort, lets hope they get on top of this problem.
