PHP Fatal error: Class 'SilverStripe\UserForms\Model\Page' not found in silverstripe\userforms\code\Model\UserDefinedForm.php on line 11

If you have your page class name spaced, the userforms module won't be able to pick up on it and will return an error.

it probably should rely on SiteTree, or use some extension magic to allow the user to specify the page type using a yml file.

Hi @torleif, SilverStripe 4 doesn't support namespacing of Page at this time. You can follow more on this topic here: silverstripe/silverstripe-framework#5844

We'd welcome decoupling from Page in this module if you'd like to submit a pull request, but I'm going to close for now. Thanks for raising the issue though =)

For reference here @torleif the work here is mostly done (abstracting this module from Page) - in order to circumvent your problem for now I see two solutions:

1. class_alias your namespaced Page class. Similar to how SS3 does for Object to be PHP 7.2 compatible
2. Make a PR to exit early if (!class_exists('Page'))

You can create a custom userform class simply by applying the traist, as is what happens with the problematic class in discussion:

silverstripe-userforms/code/Model/UserDefinedForm.php

Lines 13 to 15 in 621bc75

	class UserDefinedForm extends Page
	{
	use UserForm;

thanks @robbieaverill and @NightJar , I used the bootstrap alias as described in issue. My bootstrap.php autoloader looks like the following:

require('app/src/Page.php');


use OP\PageController as NamespacedPageController;
use OP\Page as NamespacedPage;

class Page extends NamespacedPage
{
    private static $hide_ancestor = NamespacedPage::class;
    private static $table_name = 'SilverStripe_Page';
}

class PageController extends NamespacedPageController
{
}

which allows the module to pick up on the Page class
