@edvin BTW, the sequence of steps produces only 3 visible elements 1. Enter A press return 2. Enter B press return 3. Enter C press return

That's how I do it as well 🙂 Great!

I think I can make sure that fragments are not created before they are actually needed, so if you have only 3 items it would only create 3 fragments, even if you have 10 visible cells in the ListView.

@edvin a quick check: when fails, my app shows an "Exception dialog" with the stack trace. This is from JavaFX and has nothing to do with TornadoFX, right?

exceptions are javafx exceptions as TornadoFX basically wraps and delegates to javafx

@voddan I suspect it is from TornadoFX, because if you initialized the TornadoFX app, a special exception handler is installed. Can you show me the dialog?

If it looks like this, it's TornadoFX:

See https://github.com/edvin/tornadofx/wiki/Error-Handler for more information

@ron We don't really delegate to JavaFX. We actually catch the exceptions that were uncaught and report them in the UI. It's possible to install a custom error handler as well.

@edvin I reverted the patch on my master branch and added a new branch that uses cellfragment called "cellfragment". if you clone my fork, you should be able to compare and contrast these two versions easily

@carlw Great!

Hmmz I have seen this kind of error dialog in normal javafx programs which is why I thought we delegate

I designed this masterpiece myself.. hehe 🙂

you are a genius in UX

@edvin, @Ruckus is the CSS stuff in the Wiki up-to-date?

Just asking so I can compare to the guide and update it.

Update the guide, not wiki : )

@thomasnield Looking now

@thomasnield No, there are some old stuff there. I will clean it up tonight.

@edvin yes, it looks like that

Crap! I don't want this!

It makes debugging miserable

@voddan You don't want the error dialog? That's easy, just install a custom error handler, like it's described in the Wiki link.

@voddan You just want a stack trace perhaps?

in the stdout

let me read the docs

btw, https://github.com/bekwam/todomvcFX/tree/master/examples/tornadofx by @ron was very helpful in illustrating your point on the configuration

Great 🙂
