[TYPO3-dev] Call a viewhelper in another viewhelper

[Marcel Menoud]

 Hello everybody,


For an extension, I would like to call some base viewhelpers from a custom
viewhelper :
 - The Tx_Fluid_ViewHelpers_ImageViewHelper
 - The Tx_Fluid_ViewHelpers_Link_ActionViewHelper


But I have some problems :
For the  The Tx_Fluid_ViewHelpers_ImageViewHelper, I don't know how to pass
the mandatory argument "alt", since it is not a parameter of the render
method, and without it, this viewhelper return me an empty string.
For the  Tx_Fluid_ViewHelpers_Link_ActionViewHelper, I dont't know how I
can set the child node (the text of the link)


I have create the instance of these ViewHelpers in this way in my
viewhelper :


   $objectManager = t3lib_div::makeInstance(
'Tx_Extbase_Object_ObjectManager');
   $imageViewHelper = $objectManager->create(
'Tx_Fluid_ViewHelpers_ImageViewHelper');
   $linkViewHelper =
$objectManager->create('Tx_Fluid_ViewHelpers_Link_ActionViewHelper');



Do you have an idea to a way to call these viewhelpers ?

Thank you for your help,

Marcel
