clearTagStateForTagPoolingServers()
Provide a mechanism to clear tag state, to handle servlet container JSP tag pooling
behaviour with some servers, such as Glassfish.

Descendants should override this method for custom behaviour, but should always call the ancestor method when doing so.

processing,
which may help with certain edge cases with tag logic running on servers that implement JSP Tag Pooling.
Note: Even though the Tag classes extend this class StrutsBodyTagSupport
, and this method
StrutsBodyTagSupport.setPerformClearTagStateForTagPoolingServers(boolean)
exists in the method hierarchy,
the JSP processing requires us to explicitly override it in every Tag class in order for the Tag handler
method to be visible to the JSP processing.
Defining a setter in the superclass alone is insufficient (results in "Cannot find a setter method for the attribute").
See StrutsBodyTagSupport.clearTagStateForTagPoolingServers()
for additional details.
Warning: Setting this value to true may allow for the desired behaviour, but doing so
may violate the JSP specification. Set to true at your own risk.

- true if tag state should be cleared, false otherwise.protected void clearTagStateForTagPoolingServers()
StrutsBodyTagSupport
Usage: Override this method in descendant classes to clear any state that might cause issues should the
servlet container re-use a cached instance of the tag object. If the descendant class does not
declare any new field members then it should not be strictly necessary to call this method there.
Typically that means calling the ancestor's ComponentTagSupport.clearTagStateForTagPoolingServers()
method first, then resetting instance variables at the current level to their default state.
Note: If the descendant overrides StrutsBodyTagSupport.doEndTag()
, and does not call
super.doEndTag(), then the descendant should call this method in the descendant doEndTag() method
to ensure consistent clearing of tag state.
