[TYPO3-formidable] sandbox and persitance after the FORM post.

[Didier HINGANT]

Hello all of you,

I've got a renderlet lister populated with a list of filenames.

In that lister i put a renderlet:Checksingle column to select or not
a file name in that list.

<column type="renderlet:CHECKSINGLE" name="cbselect" activeListable="true" 
defaultWrap="false" listHeader="Selection">
   <onchange runat="ajax" 
params="rowData::uid,mylist.cbselect,rowData::fl_identifiantftype,rowData::fl_nomfichier" 
 >
     <userobj>
       <php><![CDATA[/*<?php*/
          return $this->oSandBox->doAfterCheck();
         /*?>*/]]>
       </php>
     </userobj>
   </onchange>
</column>

Each time i select or deselect a record in the renderlist, i
update an array (addArray or delArray) called $liste_fichier that i store
in a sandbox var by that function :

function addArray($uid, $numdossier, $nomfichier) {

  if(is_null($this->oForm->oSandBox->iCounter)) {
     $iCounter=0;
     $this->oForm->oSandBox->iCounter = $iCounter;
}
else {
    $iCounter=$this->oForm->oSandBox->iCounter;
    $iCounter++;
    $this->oForm->oSandBox->iCounter = $iCounter;
}

// Test pour savoir si le tableau liste_fichier existe en memoire sandbox
 if(is_null($this->oForm->oSandBox->liste_fichier)) {
     $liste_fichier[$iCounter]["uid"]=$uid;
     $liste_fichier[$iCounter]["fl_identifiantftype"]=$numdossier;
     $liste_fichier[$iCounter]["fl_nomfichier"]=$nomfichier;
     $this->oForm->oSandBox->liste_fichier = $liste_fichier;
 }
 else {
     $liste_fichier=$this->oForm->oSandBox->liste_fichier;
 }
 $liste_fichier[$iCounter]["uid"]=$uid;
 $liste_fichier[$iCounter]["fl_identifiantftype"]=$numdossier;
 $liste_fichier[$iCounter]["fl_nomfichier"]=$nomfichier;

 $this->oForm->oSandBox->liste_fichier = $liste_fichier;
 }

I want to retrieve the $liste_fichier in the actionlet part of my xml after 
the form post :

      <actionlet:USEROBJ>
        <userobj>
          <php><![CDATA[/*<?php*/

                 //$actionLetMsg="Passage dans Actionlet!";
                 //debugster($actionLetMsg,array("title"=>"ActionLet","recursion"=>"10"));

                 $filelist = $this->oForm->oSandBox->liste_fichier;
                 debugster($filelist,array("title"=>"liste fichiers 
actionLet","recursion"=>"10"));

                ]]>
          </php>
        </userobj>
      </actionlet:USEROBJ>
    </actionlets>

My problem is that the sandbox var 'liste_fichier' is always null after i 
click the submit button.

Are sandbox vars persistants after a submit form ?

If someone could give me an explanation or an example with sandbox vars and 
functions.

Thank you very much.

Didier.
