[TYPO3] TV and TypoScriptObjPath in a Container

[Fabio ex Typo3 n00b]

I have made a template with template voila, I have a lib.Obj [EL] into a 
Container [CO] and doesnt work.

In typo script I wrote

lib.navLeft = TEXT
lib.navLeft.value = TRYYYYYY

In the FE doesn not appear, for other lib.Obj element [EL] out of the 
container [CO] it works.

Here a piece of code

             <field_menu type="array">
                 <type>array</type>
                 <tx_templavoila type="array">
                     <title>Menu Left</title>
                     <description>[menu left]</description>
                     <eType>ce</eType>
                     <eType_EXTRA type="array">
                         <objPath>lib.left_menu</objPath>
                     </eType_EXTRA>
                 </tx_templavoila>
                 <el type="array">
                     <field_navleft type="array">
                         <tx_templavoila type="array">
                             <title>Nav Left</title>
                             <sample_data type="array">
                                 <numIndex index="0">[nav left]</numIndex>
                             </sample_data>
                             <eType>TypoScriptObject</eType>
                             <eType_EXTRA type="array">
