Using $CI means the model is loaded into the controller, not the module system.

What is the proper way to load a model into a module library system then? Wouldn't this work?:
Code: $this->model =& modules::load('user_model');
Throws an error:
Code: A PHP Error was encountered
Severity: Notice
Message: Only variable references should be returned by reference
Filename: helpers/modules_helper.php
Line Number: 43

To be honest I think your application is becoming too complicated if you need to load a module model into a module library, there must be some more simple way to get the same result.
But for the record you can try this, but I'm not sure if it still works in the current version.
You can specify which type of class the module loader should look for:
Code: $this->model =& modules::load('user_model', 'models/');
If this errors then add the path also: 'admin/user_model'

Well, let me explain what I'm trying to do, maybe I am making it way too complicated indeed.
This particular module called 'users' handles all userstuff: signup, login, activate account, forgot password etc etc. To avoid the controller getting to bloated I moved most related functions to the 'Userlib'-library, which also does db inserts, updates etc. DB calls I have put into a usermodel which I then need to load into the userlib in order to use it.
I guess to circumvent these problems I *could* put all functions into the module controller.
EDIT: $this->model =& modules::load('user_model', 'public/users/models/'); seems to be working!

Cool, glad it worked. 
Another little feature you may or may not know is that modules can have seperate method files. So the module can be extended without clutter.
Create a methods directory under the module name:
Code: module_name/
- config/
- controllers/
- users.php
- helpers/
- language/
- libraries/
- methods/
- signup.php
- forgot_pwd.php
- register.php
- models/
- plugins
- views/
methods can be loaded in the module: $this->load->method('some_method'); and used like libraries or they can be called as part of the module, they will be loaded and run automatically.
modules::run('module', $data, 'some_method')
Methods need to extend YOUR module controller class but they dont need to have a constructor and they have access to everything the module does.
I hope this is some help

I don't know if I am doing something wrong, but this
Code: $this->parser->parse('module_name', $data);
inside a module do an error:
Code: Unable to locate the requested file: /views/module_name.php
This is OK if I write:
Code: $this->load->view('module_name', $data);
Is something wrong in my code?
If not, can I use the CI parser with HMVC inside modules?

Use this parser helper.
Code: <?php if (!defined('BASEPATH')) exit('No direct script access allowed');

Thank you. I learnt a lesson with the use of $this in a static method. By the way, you have an error. It must be:
Code: if (!preg_match('/{'.$variable.'}(.*){\/'.$variable.'}/s', $string, $match))
I have reached another solution (not so elegant as yours) in the meantime:
Code: <?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Parser extends CI_Parser
{
function parse($template, $data, $return = FALSE, $object = NULL)
{
if ($object === NULL)
{
$object =& get_instance();
}
$template = $object->load->view($template, $data, TRUE);
if ($template == '')
{
return FALSE;
}
foreach ($data as $key => $val)
{
if (is_array($val))
{
$template = $this->_parse_pair($key, $val, $template);
}
else
{
$template = $this->_parse_single($key, (string)$val, $template);
}
}
if ($return == FALSE)
{
$object->output->final_output = $template;
}
return $template;
}
}
And in the module:
Code: return $this->parser->parse('view', $data, false, $this);
Maybe it can be useful to somebody.

Corrected thanks.

Version 4.0.29 is available on the wiki
Corrected a bug in modules::load to return a valid reference.
