Subject: Commands Promise: module => true. External created variables not
useable within other functions

Hi,
i have a problem concerning the "transfer" of a variable to a function which
was read via the commands promise "module" -> true.
It starts the script "zonesscript" which contains:
/bin/echo =regex= VM.*
This creates a new variable (zonesscript.regex) within cfengine.
I can use the value (=VM.*) within parts of Cfengine without any problems. I
can make a report promise and the correct value is used.
But if want to use the value of the variable in the bundle edit_line fillzones
() it is simply not working. (see example below)
The value of the variable zonescript.regex is NOT transfered to the getfields
Function. Although i can make a report promise and "print" $(r) with the
correct value. The getfieldsfunction is NOT using them at all. If i replace:
"zones_nr" int => getfields("$(r)","$(g.zones_csvdata)",";","zones_array");
with:
"zones_nr" int => getfields("VM.*,"$(g.zones_csvdata)",";","zones_array");
everything works. But i want the input from the script....
How can i use the value of the variable "regex" from the external "zonesscript"
within getfields() function?
Thanks (again) for your help.
----------------------------------------------
Simplified Example. May contain (other) errors cause i cut out several lines to
make it shorter:
------------------------
body common control{
bundlesequence => {"cfg_init_zones", "cfg_create_zones"};
}
bundle common g {
vars:
# Several unimportant vars (not included in this example)
bundle agent cfg_init_zones {
commands:
zones::
"$(g.zones_script)"
module => "true"; }
bundle agent cfg_create_zones {
files:
"$(g.zones_template_output)"
create =>"true",
edit_line => fillzones("$(g.zones_temp_file)", "$(zonesscript.regex)");
}
bundle edit_line fillzones(template,r)
{
vars:
"zones_nr" int =>
getfields("$(r)","$(g.zones_csvdata)",";","zones_array");
"zones_idx" slist => getindices("zones_array");
insert_lines:
# no complete example
}
