[opencms-dev] Analyzed but not solved yet: Broken behaviour of contentload/show/info tag

Well, simple.
In the "release()" method m_locale is set to null, but the release method is 
not called from request to request...

From the J2EE Javadoc:

javax.servlet.jsp.tagext.Tag Interface:


Lifecycle details are described by the transition diagram below, with the 
following comments:

    * [1] This transition is intended to be for releasing long-term data. no 
guarantees are assumed on whether any properties have been retained or not.
    * [2] This transition happens if and only if the tag ends normally without 
raising an exception
    * [3] Note that since there are no guarantees on the state of the 
properties, a tag handler that had some optional properties set can only be 
reused if those properties are set to a new (known) value. This means that 
tag handlers can only be reused within the same "AttSet" (set of attributes 
that have been set).
    * Check the TryCatchFinally interface for additional details related to 
exception handling and resource management.



public void release()

    Called on a Tag handler to release state. The page compiler guarantees 
that JSP page implementation objects will invoke this method on all tag 
handlers, but there may be multiple invocations on doStartTag and doEndTag in 


Kind regards, Bernd Wolfsegger
