Description
I have a radio "contactType" with default value preset. Depending on the contact type I want to add dynamic validation to following input fields (email, phone, ...). The configuration looks like this:
-
identifier: contactType
type: RadioButton
defaultValue: email
properties:
optionClass: c7of24
options:
email: 'E-Mail'
phone: 'Telefon'
mail: 'Post'
-
identifier: email
type: Text
properties:
type: email
variants:
- identifier: contactType-email
condition: 'formValues["contactType"] == "email"'
validators:
- identifier: NotEmpty
- identifier: EmailAddress
Sadly, I get the following Exception on the initial form call:
PHP Warning: Undefined array key "contactType" in /var/www/html/www/vendor/symfony/expression-language/Node/GetAttrNode.php line 97
Running TYPO3 11.5 with PHP 8.0.

Seems like the cause is somewhere deeper. There are various issues with conditions if the offset value doesn't exist, e.g. #95781 or #97624
For now, I have the following workaround:
condition: 'traverse(formValues, "contactType") == "email"'
Maybe this helps someone. Thanks to Stefan Bürk for pointing me this way.
