[Tapestry-developer] PopLink

[Joseph Panico]

At Howard's suggestion, I've started thinking about reimplementing the current PopLink as a "wrapper" to the existing dynamic Tapestry link types, something along the lines of Rollover.

A couple of issues have cropped up. Someone has suggested/requested "Pop" functionality for Buttons, not just Links, and that obviously makes sense. Rollover is used by wrapping the Rollover with a Link, but a Button can't wrap anything. So this suggests that the Pop should wrap the control (Link, Button, etc), rather than be wrapped by it. Like this:

<span jwcid="detailPop">
<span jwcid="aLink"/>
</span>


Also, in my mind (YMMV) the markup is more intuitive this way than the other way around.

If there is a single Pop component that can wrap disparate components, like Link, Button, etc, there is the issue of how to provide type-safety for the thing that gets wrapped. The Pop could look at the type of the thing that it wraps and check it against a laundry list of valid taypes. Obviously this is a pretty clunky design. The prettier solution would be to introduce a "tagging" interface "Popable" that any wrapped component would have to implement.

Howard, let me know if this makes sense.
