thanks for clarifying.
indeed today, the canDoActionMessages is simply a collection of strings, each
of which is either a message, a message with variable placeholder(s) or a
variable value; if a few messages contain an identically-named variable
placeholder (e.g. '${HostName}'), and you want to replace each one of these
placeholders with a different value (e.g. 'host-A', 'host-B', etc.), it is
impossible to do AFAIK.
a possible improvement to the current mechanism in order to support what you
need is to define the canDoActionMessage field to be a collection of string
collections (rather than a collection of strings); and each string collection
will actually represent a single 'line' in the can-do-action failure message,
by containing the 'base' message (e.g. "Host '${HostName}' failed
constraint
memory") and its matching variable value(s) (e.g. '$HostName host-A').

Hi Einav,
I know about this procedure, but if you check closely what I am doing, I need
to print a list of messages at once where each has a different content.
Something like this (again the strings are just an illustration):
------------- Error ----------------------
The VM net-A could not be started because
there was no fitting host available.
Host host-A failed constraint memory
Host host-B failed constraint cpu load
Host host-C failed constraint memory
------------------------------------------
I am pretty sure the replacing we have in VdcBllMessages does not support
this as it cannot assign two or more different values to the same variable.
