qweb_report_parameter t-lenght does not work with t-out code

[angelmoya]

t-lenght is not applied with t-out with code

Module

qweb_report_parameter or l10n_spain/l10n_es_facturae

Describe the bug

On OCA/l10-spain, on facturae module, this t-lenght is not applied:

<ContactPersons t-length="40" t-out="administrative_partner.name or partner.name" />
https://github.com/OCA/l10n-spain/blob/908103615bd3e2a9d810afa14ae631a995070ae2/l10n_es_facturae/views/report_facturae.xml#L183

But this is applied right:

<TradeName t-length="40" t-out="partner.name" />
https://github.com/OCA/l10n-spain/blob/908103615bd3e2a9d810afa14ae631a995070ae2/l10n_es_facturae/views/report_facturae.xml#L123

I tested on runbot, with this result:
<CorporateName>Deco Addict2345678901234567890123456789012</CorporateName> <TradeName>Deco Addict23456789012345678901234567890</TradeName> <AddressInSpain> <Address>77 Santa Barbara Rdsdg</Address> <PostCode>30740</PostCode> <Town>Pleasant Hill</Town> <Province>Murcia</Province> <CountryCode>ESP</CountryCode> </AddressInSpain> <ContactDetails> <Telephone>(603)-996-3829</Telephone> <WebAddress>http://www.deco-addict.com</WebAddress> <ElectronicMail>[email protected]</ElectronicMail> <ContactPersons>Deco Addict23456789012345678901234567890</ContactPersons> </ContactDetails>

You can check that TradeName is limited to 40, but ContactPerson is not limited.

To Reproduce

Affected versions: 16.0

Steps to reproduce the behavior:

1. Go to l10-spain report runbot
2. Select ES Company
3. Configure spanish state and vat on company
4. Create invoice for a partner with spanish state and vat
