Created attachment 264215 [details] Good (Left) and bad (right) screenshot Version: Papyrus & SysML 1.4 today's nightly (20160915) Scenario: * Draw an IBD with a port on an edge. * Resize the port. * Save the model. Observation: Sometimes the port's size is retained, sometimes it isn't. I didn't find a good reproduction strategy, but it seems I have it once a day or so (on my Windows PC). Also confirmed on a Mac, so I guess it is not specific to the model instance, nor the PC/platform instance. It seems the upper-lefthand corner of the resized port is retained, but the size isn't, so the port is shown in default size at a location away from the edge. The attachment contains two screenshots: * Good one * Bad one (from a different model, but also there the port was just resized).
Might not necessarily be a SysML 1.4 problem, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=466572#c3 (but I can confirm the bug)
Created attachment 264217 [details] Small model with peristent issue. The attached small model shows a situation that I can't get out of: * Has a resized port * Has a port inside this resized port --> I can't resize anymore.
I didn't manage to reproduce the problem either on neon or oxygen. I resized the port in the attached model without any problem. Did you got any log on the subject?
Hi Benoit, this looks more and more like a race condition to me. When I open the attached model in a brand-new workspace, it fails. When I try to move het port a bit, restart Eclipse etc, it can get working again. Then it keeps working for ever (or at least as long as I tried ...) I can make it fail again by removing the .metadata and importing the project again. As far as Exceptions are concerned: * I saw once (but I lost the error.log) gmf complaining about an invalid position. * I did see (once) a message from declarative services, but I guess that is not related. * Additionally, I see some messages about "refresh inside refresh" and an exception. Strangely enough, I did see that only in a case in which it "automatically" switched from non-working to working. !ENTRY org.eclipse.papyrus.infra.core.sasheditor 2 0 2016-09-29 10:07:13.628 !MESSAGE

I did another experiment since this problem remains very apparent in all what we do: * I created two separate projects, one with a Composite Structure diagram and the other with an Internal Block diagram that looks very similar. See the model attached "Comparison CS/IBD model". * I added the same style sheet in both projects, although I think it is irrelevant. * I opened both next to eachother, see attached screenshot "Comparison CS/IBD screenshot). * I restarted Eclipse several times (about 20): - In about 30% of the cases, the FullPort shows as the one in my screenshot. - The equivalent port on the CS diagram shows correctly every time. Conclusion: * There has to be a difference in the behavior of IBD vs CS * It feels like a race condition

@Johan: there are differences but small and not directly related to port. css is the first one I can think of - css file - css parser (GMFSYSMLElementAdapter same for all SysML 1.4) => Do you have the same behavior in Parametric?
I've experienced the same issue while working with a potential customer. In my case, I have created a model crafted for demonstrating nested ports, which I saved and exited Papyrus. After restarting Papyrus and opening the model the port sizes were rest to the default and could not longer be changed. However, the relative position of the "container" and nested port was enforced, i.e., moving the container port resulted in the nested port following it, even though there was no longer a "containement" visual indication. I will try again the same scenario in order to see if it can be replicated.
Hi Charles, the behavior that you describe is in line with with what we see; positions linked, but "parent" port only has its upper lefthand corner still in the correct place. Its size is back to the "normal" port size. With respect to Benoit's question, I guess it is important to know whether your reproduction was on SysML, on pure UML or on a profile such as Papyrus-RT.

It was with SysML. Papyrus-RT does not support resizing ports, nor does it support nested ports (it uses structural nesting and delegation connectors to accomplish a similar result), so it would not be an issue. Does UML support nested ports? I could not find that in the 2.5 spec (although I may have missed it). I thought it handled such things through structural nesting and delegation connectors.
Charles, a Port is a TypedElement (some levels higher in the inheritance hierarchy) and can therefore carry a Type. A Component is a Type and as far as I see, UML does not specify a Port's type to not being a Component. A Component can have ports, so a Port can have "nested" Ports. I don't know whether the graphical representation of a Composite Structure diagram says a lot about the visualisation of nested ports. At least, what I see is that in Papyrus it works for Composite Structures and I'm unable to make it fail on that diagram (as opposed to an IBD).

Agreed, UML supports "nested" ports but does not define "nested ports".
To be clear. This is not nested ports. We display ports of the the type of the port. exacatly the same case for part of the type of a part. There is very important to make the difference. ;D
Right. That's why I put "nested" ports with the nested between double quotes in comment #12.
For information: - this problem may have been fixed by the patch provided for Bug 508172 Since I couldn't reproduce the problem systematically, I can't affirm that it works now. Feel free to comment if you can reproduce the problem with the current nightly update site.
Benoit, I can confirm that it is fixed on any IBD that I try. Unfortunately, I see that it still occurs on BDD. Probably the same fix can be applied there?
I fear that it's not so simple for BDD. I regularly check/test/look in the code, but so far I have no idea on what's causing the bug. @Patrick: most of the implementation is done in expansionmodel framework, as its creator do you have any pointer/tips on this really annoying bug ?
Still here on BDD on Papyrus 2018-12
