Hi,

i am still trying to find out how i can validate fields of a DataObject in CMS.
My first steps are using the function validate()

class News extends DataObject {

...
public function getCMSFields() {
...
}
...
public function validate() {
$valid = parent::validate();

if ((!$this->Title) || ($this->Title=="")) {
$valid->error("Titel");
}
return $valid;
}
...
}

But with this I get the following:

[User Error] Uncaught ValidationException: Validation error writing a News object: Titel. Object not written.
POST ............/admin/EditForm/field/HomepageNews/AddForm

Line 715 in ........../sapphire/core/model/DataObject.php

So how do i have to catch the exception?
Thanks

Hello,

I'm very interressting by the response too ... I have the same problem !

I don't think it's the misspelling title because the first param of this error() method should be a message, a string (cf http://api.silverstripe.org/2.4/sapphire/core/ValidationResult.html#methoderror)...

Thanks for your help.
