Hello,

I don't know where to contact developers. So I'm writing about my problem here. Variables and classes are not evaluated in mustache templates from namespaces other than default. For example, I have a policy file for creating autofs map file, which looks as follows:
`body file control
{
namespace => "autofs";
}

bundle agent autofs
{
vars:
linux::
"template" string => "$(default:sys.workdir)/inputs/templates/ws/autofs.mustache";
"hyperbeam_nodes" slist => expandrange("hyper[001-020]", 1);
classes:
linux::
"hyperbeam_workstation" expression => "alm_test";

...
files:
linux::
"/etc/autofs.map"
create => "true",
perms => set_perms("0644"),
edit_template => "$(template)",
handle => "restart_autofs",
template_method => "mustache";
}
And the template file autofs.mustache:{{#classes.hyperbeam_workstation}}
{{#vars.autofs:autofs.hyperbeam_nodes}}
{{.}}
{{/vars.autofs:autofs.hyperbeam_nodes}}
{{/classes.hyperbeam_workstation}}
`
So the class hyperbeam is not triggered form the namespace autofs when cf-agent is running. The variable hyperbeam_nodes is also not expanding from autofs namespace, using the syntax vars.autofs:autofs.hyperbeam_nodes.

I have read the Cfengine documentation and did not find anything about accessing variables and classes from different namespases in mustache templates.

Hi @favoritelotus

The best place to report issues is in the CFE project on tracker.mender.io.
This is mentioned in the contributing guidelines doc here

I copied this comment into a new ticket: https://tracker.mender.io/browse/CFE-3497

Hi @favoritelotus, FYI, it's working for me to render using non default namespace classes and variables, see the ticket for an example.

Hi Nick. Thank you for giving the working example. It turned out I used a wrong syntax in mustache templates, referring to variables and classes defined in policy files. Following your example, I have rewritten templates, and now the decision logic is working correctly based on defined classes with correctly expanding variables. Thank you. Regards, Pavel.
