That assumption is correct

I mean some TALES expression as here/getDataInici | string: nosta will evaluate here/getDataInici and if this expression returns '', 0 or None the tal interpreter evaluates the second one and the result of this TALES expression will be nosta as string

Is this assumption correct?

Thanks!

Hi!
Please consider this TALES expression:

<div class="DataPrevista" tal:content='here/getDataInici | string: nosta' />

If I try this other: <div tal:content='string:${here/getDataInici}' /> the result is <div>None</div>

Then the first one will render the alternate expression isn't it?

Then with it renders <div class="DataPrevista" /> ?

Thanks!

I don't understand what you are asking. Could you describe your question more clear please.


Martijn.
