Sorry for the noise, I struggled with """ for long time and didn't
realise that I wasn't need "eval()" anymore...
I don't need js var and eva(); at all as long as I have XML()
# In view
{{if request.args(0)=='SOMETHING':}}
<script type="text/javascript">
{{=XML(conditional_field_trigger_selected_event_js)}}
</script>
{{pass}}
