This code works with ansible 1.9.4

> with\_items: “{{ zabbixagent\_userparameters }}”  
> when: zabbixagent\_userparameters is defined  
> notify:
> - restart zabbix-agent

But not working with 2.0.0.1

the lookup is returning a list, not a string, as a workaround:

template: src={{ lookup('first\_found', [ 'userparameter\_' + item +  
'\_' + ansible\_pkg\_mgr + '.j2', 'userparameter\_' + item + '.j2' ])[0]  
}}

thank you very much.

is it make any sense that first\_found return a list ?  
i think that _first_ means that list will always contain 1 element.

looking into that, for most lookups the answer is 'yes', in this case  
it can be considered a bug, you should open an issue in github.
