Sequence diagrams in 2.0.1 [message #1745724]

I'm having multiple problems making sequence diagrams. Having encountered Bug 486006, fixed in 2.0.1 (thanks!) I've upgraded to that - but now I can't build the simplest diagram. I'm not sure whether there are bugs, or whether I am just misusing the tool. What would be brilliant would be if someone would make a video of using Papyrus 2.0.1 to build a sequence diagram showing, say (taking the example I was trying to build for my students):

- a lifeline for an instance of actor Lecturer;
- one for a Course, one for a Student;
- the Lecturer sending registerStudent to the Course
- the Course sending isFull to itself [getting answer false, don't care if this is shown]
- the Course sending hasPrerequisites to the Student [answer true, ditto]
- the Course sending register to the Student
- correct return messages and nested activations (ExecutionSpecifications)
- ideally also proper connections to Operations in the class diagram, arguments to the messages etc., but that's less crucial.

Seems as though it should be easy for someone who knows what they're doing? Thanks in advance!

As the author of the 486006 bug report, I just can say: "no problems doing sequence diagrams with 2.0.1".

Thanks! Doing apparently the same, though, I get different behaviour. Here's a video of one kind of misbehaviour I experience (there are several, and so far, I am not able reliably to reproduce them all on demand - but I've never managed to get all the way through to producing the diagram I want!) [Actually, am failing to get this reply posted with the video attached: let me see if it works without, and if so, I'll worry about whether the video may be too big or something.]

Which Java version is in use. I got weird behaviour testing Papyrus 2 RC3 on Java 9.

Stuck my two videos on YouTube since for some reason eclipse.org didn't seem to want to upload them.

One kind of misbehaviour:

Another kind:

Any help very much appreciated!

Appearently you use Windows 10. My setup uses Ubuntu 16.04 with Gnome as desktop. On Thursday I might get time to setup and test it on a Windows 10 machine.

It's at home on Windows 10 that I can easily use the latest Papyrus and video, but I have similar problems using 2.0.0 on Scientific Linux at work. I don't think I've seen precisely the same as in my first video, but I have seen the problem shown in my second.

Fascinating as Spock tends to say.
I will reflect on it.

Edinburgh is indeed a nice place Smile

Tiny update: though I haven't explored extensively myself, my lab-full of students today seemed to be building sequence diagrams without problems, with Papyrus 2.0.1 - which is an interesting contrast with my Windows 10 experience, though they weren't trying to do exactly the same things!

argh, I should proof-read better. The point is that my students were using the 64-bit Papyrus 2.0.1 distribution from the download page, on SL7, whereas my bad experiences were with Windows 10. (On the downside, they then encountered https://bugs.eclipse.org/bugs/show_bug.cgi?id=345882 , i.e. couldn't show details of state diagram transitions, something I'm pretty confident we all did with 2.0.0 a week or two ago. Reminds me why for years I've taught modelling only using paper and pencil...)

You seem to have run into at least one bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=502154
I am not sure this explains all the weird behaviors you are experiencing though, and if your students didn't run into it it's even weirder...
