When you have a parametrised build trigger using a build parameter to select a list of builds to trigger the following happens: 1st build after a jenkins restart works fine, while the 2nd keeps the parameter values from the 1st. (Or at least it seems so: please find details/proofs in the attachments).
Still no clue if this comes directly from this plug-in or from some other related to it or (maybe) it's a core jenkins issue (the jenkins was update really often lately plus I had new plug-ins installed/updated so it's hard identify a reason).
The "test" build I used is following:
- trigger builds from the CCC variable (non-conditional build step)
- trigger another build only if BBB is true (conditional build step)
In the 1st run I select BBB=true, CCC="TEST 2, TEST3"; and the build proceeds as expected triggers builds TEST 2 & TEST 3, and then a conditional build step.
In the 2nd run I select BBB=false, CCC="TEST 1"; and proceeds in a very weird manner it still triggers builds TEST 2 & TEST 3, like before - so I assume it somehow takes the old value for the parameter CCC, but then doesn't trigger the conditional build - so I assume it now takes the current value for the parameter BBB.
I am pretty sure it was working fine before (a few weeks ago) I have no proof for it.

added a comment - Actually it doesn't seem related to the conditional build plug-in but to the Jenkins Parameterized Trigger plug-in, I'll change the component.
The reason I thought it's conditional build plug-in is that before installing it everything was working fine.
I also updated the description.
Note: the description & screen-shots still contain the conditional build plug-in but I've tested it today with out conditions configured and there's the same behaviour, if you want I can attach new/more screen-shots.

added a comment - Any update on this one? it is a real issue for us.

added a comment - Hi,
I believe I have the same issue and it's rather easy to trigger;
Setup a project with one parameter and one build step - "Trigger/call builds on other projects". In the "projects to build" let it expand the parameter.
Now I'm new to the code base, but I would say that the cause lies in BuildTriggerConfig.java and this comment;
// the list of projects to build is computed in getProjectList() ; this method // is actually invoked twice (when in a build step), so let's cache its result private transient List<AbstractProject> projectList;
This implies that the BuildTriggerConfig is cached on some other level, so it may be that it has worked before and broke due to other optimizations.
I haven't had the chance to test it yet though, due to administration issues...

added a comment - I have the same problem and would like to see a bug fix soon, because currently we have to start our builds twice..

added a comment - Can you retry this test with 2.15, as the caching of the project list was removed in this version.
I have tested this and not seen the error but want confirmation from other user before this issue is closed.

added a comment - Yeap I've tried it and it works fine. 
so far, I'm not able to reproduce this issue, but:
