/**
* Gets the error(s) of a field currently stored in the FormBuilder-object.
* Furthermore: If it is the first element of an array (e.g. domainName[0]),
* the errors of the array itself are also returned.
* This even works for multidimensional arrays.
* Example:
* This server-side request array:
* domainList => [
* 0 => [
* domainLabel => 'first-domain',
* domainPdo => 'at',
* ],
* 1 => [
* domainLabel => 'second-domain',
* domainPdo => 'at',
* ],
*
* Returns errors in the following structure:
*
* - Field 'domainList[0][domainLabel]' returns errors for:
* - domainList[0][domainLabel]
* - domainList[0]
* - domainList
* - Field 'domainList[0][domainPdo]' returns errors for:
* - domainList[0][domainPdo]
* - Field 'domainList[1][domainLabel]' returns errors for:
* - domainList[1][domainLabel]
* - domainList[1]
* - Field 'domainList[1][domainPdo]' returns errors for:
* - domainList[1][domainPdo]
*
* @param string $name
* @return array
