Custom Tag, Custom Rendering

Question

I've got a custom tag thats fairly basic such as the following:
<my:page>
</my:page>Now when the PageTag class runs, I want to have it query a database and grab a list of items and print them out such as:
Item 1
Item 2
Item 3
However I want to be able to override the way it prints out a particular item, so if I do something like:
<my:page>
<my:override dbitem="Item 1" replaceTextWith="Item 4" />
</my:page>Then I want to get something like:
Item 4
Item 2
Item 3
In other words, it needs to stay in order. So what I need is control of the children rendering process so I can replace the database row with the overridden item. Now this is an over-simplified method of what I am trying to do, for instance the <my:override> tag will actually have to render HTML, it cannot just be invisible and call its parent (<my:page>) and set some flag to override, it has to be standalone as well.

Answer 1

I figured out how to handle all this, If you have a similar issue, look up extending BodyTagSupport instead of TagSupport. BodyTagSupport gives you much more control over the design and presentation of your tags.
