thanks oscar, john and jordi
a cool syntax, the for/else, twig is really useful :-)
actually i need to distinguish whether i have 0 children, > 0 children
or the children array is missing, which means the code did not check
whether there where children or not...
so what i am going to combine your explanations into something like
{% if entry.children is defined %}
{% if entry.children|length %}
children
{% else %}
no children
{% endif %}
{% else %}
undefined
{% endif %}
