ZF-2810: Non-public methods in Zend_View_Helper_Placeholder_Container_Abstract trigger PHP warnings


When using view helpers that extend {{Zend_View_Helper_Placeholder_Container_Standalone}} (HeadMeta, HeadTitle, etc), calling methods that will proxy to the container class will fail when those methods are not public. Currently, there is only one non-public method in {{Zend_View_Helper_Placeholder_Container_Abstract}}, which is {{_getWhiteSpace()}}. This is used when specifying indentation in the {{toString()}} method, and will trigger a PHP warning on line 207 in {{Zend_View_Helper_Placeholder_Container_Standalone}}.

Either, the {{_getWhiteSpace()}} method should be made public and the references to it should be updated, or there should be a check in the proxy to discard calls to non-public methods.


Scheduling for RC2... if possible.

Resolved in trunk and 1.5 release branch.
