RV: [Chameleon] Custom Widget, read value of input text in Draw Publish

[Julien-Samuel Lacroix]

Hi,
To read any form variable anywhere in a widget use this:
$this->lb = $this->getVar('especie');

There's also the function $this->isVarSet('especie') that is used to 
know if a variable is set or not in the form variables.
