Hi, We have a sequence diagram which is based on your example of the sequence diagram. We want to add the possibility of a self-transition however, I can not get it to work: somehow the link always ends up in the middle of the lifeline (which is the middle of the node). It looks like the result of …

Ah, yes, the sample does not support drawing reflexive links in a special manner. I can look into that.

Something like this will be in version 1.5, but should work in 1.4: [code] // a custom routed Link function MessageLink() { go.Link.call(this); this.time = 0; // use this “time” value when this is the temporaryLink } go.Diagram.inherit(MessageLink, go.Link); /** @override */ MessageLink.pr…

Thanks! Self-transition/reflexive link is working now. And as usual your help was very quick and spot on; thanks again. -Paul.

Hi, I have an additional question: I am using above code also for our state diagrams. For these state diagrams we use “dot” as external tool for doing the layouting. For normal edges, go-js does take over the initial filled points array but changes the start & end point by snapping them to the node…

It seems to me that your requirements a bit self-contradictory. You say that you want to specify all of the points of the route, and yet you want GoJS to automatically compute the first and last points of the route. But I think I see what you want, and that sounds reasonable. How are you defining…

Hi Walter, Thanks for your answer. This is how my computePoints looks now: function SDLink() { go.Link.call(this); } go.Diagram.inherit(SDLink, go.Link); SDLink.prototype.computePoints = function() { if (this.fromNode && this.fromNode === this.toNode) { return true; } else { retur…

PS: Can it be that the notifications of the forum is broken? I did not get any notification of your previous reply of 4 days ago (checked my email and spambox).

The default implementation of Link.computePoints does treat reflexive links specially when routing, but the code is all shared with all of the non-reflexive cases. Now that I try it, I see what you mean about in the default case not restoring a custom route of a reflexive link. We’ll need to inves…

Ah, the problem is in the State Chart sample, not in the library. Basically, there are two independent data properties that are telling the link how it should be routed. There’s the “curviness” property, which is data bound in the Link template with the Link.curviness property, and there’s the “po…

Cornerning the email notification: no, I had a look at the forum after 4 days wondering why I did not get a responce yet since normally you guys have a excellent response rate; and also of hight quality, a combination you do not see very often ;-)
