I would like to customize my workflow so that some transitions could be invalidated depending on the context.
Use case:
- Let's say my classic workflow is made of 4 states : {A}
{B} {C} {D}
{B} - Let's say I have another transitional status "Z" that could be reached from statuses "B" and "C": {B} [Z] or {C} [Z]
- Being in "Z" status, I want to be able to go back to "B" or "C" ( {Z} {B} or {Z} {C} ) but I want to restrict my workflow so that I only can transit from Z to C if the previous status was C – same thing for B)
- So I want to authorize {B} {Z}{B} or {C}{Z}{C}
- But I want to forbid {B} {Z}{C} and [C]{Z}{B}
I've been looking for a solution with plugin (but no event raises for transition list) or with custom functions but nothing seems appropriate except hacking the core of Mantis.
Any suggestion except duplicating Z status?
Thanks in advance
