Hi,

all the translation is done in yafowil.utils.Tag.__call__. I'd suggest to implement it there.

https://github.com/bluedynamics/yafowil/blob/master/src/yafowil/utils.py#L128
https://github.com/bluedynamics/yafowil/blob/master/src/yafowil/utils.py#L152

We need to check for dicts and probably lists here and do a modification of the inner values recursively.
There's some chance that we need to adopt yafowil.yaml, but i'm almost sure the i18n translation strings are created properly there inside data dicts.

Yes, but only if Dict-Like attributes are parsed recursivly, please see conestack/yafowil.yaml#6

This commit here is only for expressions in dict-like attributes

Take a look what callback gets generated from expr: here https://github.com/bluedynamics/yafowil.yaml/blob/master/src/yafowil/yaml/parser.py#L153. The proper call for fetching the value then would be yafowil.utils.callable_value, but this expects widget and runtime data instances as arguments. So we would need to change as_data_attrs signature. A short grep through my dev setup shows that as_data_attrs is used in yafowil package and in yafowil.widget.richtext. And if we change the signature the code should be consolidated with yafowil.utils.data_attrs_helper.

btw - you can checkout yafowil.demo and run it's buildout if you need a full yafowil development setup
