Tag.setParent() method

[Andrew Rigsby]

For simple tags implementing the SimpleTag interface, the setParent() method is only called when a tag has an enclosing parent.

Is this also the case for classic tags? In other words, is the Tag.setParent() method only called when a tag has an enclosing parent or is the method always called?

Cheers!!

From what the specs says :

Classic tags :
The JSP page implementation object invokes setPageContext and setParent, in
that order, before invoking doStartTag() or doEndTag().

Simple tags:
The setJspContext() and setParent() methods are invoked on the tag handler. The setParent() method need not be called if the value being passed in is null.

Hi,

for Simple custom tag model following method sequences might be called by the JSP container,

setJspContext, setParent, doTag

for classic custom model,

setPageContext, setParent, doStartTag,doEndTag

So these are the container call back methods.

I think setParent() method will be bypassed if this tag doesn�t have a custom action for a parent.

correct me If I am wrong.
