[henshin-dev] Proposal to remove direct creation of edges

[Gregor Bonifer <gregor.bonifer@xxxxxx>]

Hi all,

I am currently adapting the tree-based editor to support editing of 
multiRules. This means that changes in a rule's LHS or RHS are directly 
propagated to all multiRules. In this context a problem occured with 
creating edges. If an edge is created directly in a graph it has neither 
source nor target. Therefore identifying the dependent edges of a kernel 
edge becomes kind of a guessing game. To solve this issue I would like 
to exclude edges from the "Create Child" and "Create Sibling" menu. 
Edges should always be created by commands which imply setting the 
source and target references such as the Adv.Edit. > Create Edge or 
Create Path Commands. Are there any objections?

Regards,
Gregor
