Smarty variable not assigned anymore

[Bluedge]

Hello,

I have a custom made module working fine since a year, I wanted to had a simple hook. The hook is well registered and active but the smarty variables are not assigned anymore.

 

As test : I have tried to add a smarty variables to other module and it never gets output.

Removing an existing smarty variable works (it becomes missing in the template)

 

What ever I do the smarty variables don't get assigned anymore. HELP PLEASE !!!

 

Note : I have clear the cache

 

Here is the very simple test code: 

public function hookDisplayMyTest($params) {
  $this->smarty->assign('hello', 'world');
  return $this->display(__FILE__, 'destinationsbottom.tpl');
}

It's $this->context->smarty->assign

I have done that, thanks.

Weirdly enough I had to kill apache and restart to see any effect.
