[ELK] SOUTH ports and NORTH ports are overlapped [message #1790601] Wed, 13 June 2018 08:15 Go to next message
Eclipse UserFriend
Hi,
In my diagram, I have a compound node container which has several children, including its ports and children node containers. When my parent node container has SOUTH or NORTH ports, which are unconnected and have no edges, these SOUTH and NORTH ports are overlapped.
I have no idea about when these SOUTH and NORTH ports ' position are fixed. Can you give me some hints or tell me how to fix this issue?
I use this property: HierarchyHandling.INCLUDE_CHILDREN

Thanks and hope for your reply.

Hi there,

could you illustrate with a screenshot? Also, which version of ELK are you running?

Cheers,
Chris

Hi Daniel,
Thanks for your replay.

I attach the screenshot and our ELK version is V0.2.2.
index.php/fa/33160/0/

More information as lee lucky said.

Thanks,
Nicholas Kong

Nicholas,

thanks for providing more details. I've tried to reproduce your graph as follows:

hierarchyHandling: INCLUDE_CHILDREN

node parent {
	portConstraints: FIXED_SIDE
	
	port W1 { ^port.side: WEST }
	port S1 { ^port.side: SOUTH }
	port S2 { ^port.side: SOUTH }
	
	node child {
		port P
		
		node innermost
	}
	
	edge W1 -> child.P
}


With the current version of ELK (0.4.0), this graph is laid out like this:

index.php/fa/33170/0/

Either I have missed some particular configuration that leads to the problem you observe, or it is due to a bug in 0.2.2 that we have since fixed.

Cheers,
Chris

Hi,
Thanks for your reply. I tried it in ELK 0.4.0, the south and north ports are not overlapped, but they are overlapped in ELK 0.2.2, it is a bug in 0.2.2, and 0.4.0 has already fixed it. Sorry about that.

No worries, glad it works for you. :)

Hi,
I use ELK 0.4.0 with the following properties to layout my diagram, I met an exception:

In my source codes, I just customized my port side according to my semantic model information, and I did not changed the source codes of ELK 0.4.0.
I have found that if "LayeredOptions.PORT_CONSTRAINTS, PortConstraints.FIXED_SIDE" and "CoreOptions.HIERARCHY_HANDLING, HierarchyHandling.INCLUDE_CHILDREN" both exist, the exception will occur, Do you met this kind of problem? Did I have something wrong with my configuration or it is a bug? Please give me some suggestions.
Thanks and hope for your reply.
