Hello,
I have a process definition where some kind of template is defined
with <set variable="foo">...</set> and later used in several
expressions where dollar substitution is used to merge the template
with current workitem attributes.
Therefore I would like to escape the dollar parameters in the template
variable, to prevent the substitution from taking place in the <set>,
when the workitem attributes to be merged are not defined yet. Instead
the substitution should take place in the expressions where the
template variable is used, just like the template parameter in the
MailParticipant does.
I thought I could use "\${...}" which would then be unescaped by <set>
to "${...}" instead of being substituted. That would be perfect for
me. However, the "\${...}" remains unchanged and prevents the
substitution in the expression. I also had a look at the code in
dollar.rb and I couldn't figure out how the unescape is supposed to
work.
Does anyone have experience with the escape feature in dollar
notation? Any chance of particular functionality being defect?
Thanks in advance for any help.
Maarten
