Tree children won't animate first time

[jake247]

I have a tree (FB 4.5) which has lots of branches (> 20) with many children (also > 20 per branch). The animation for opening or closing a branch doesn't seem tom occur until the item has been opened at least once. Is there any way to force the animation to occur all the time?

This is because the children don't render until you actually open it. There's a creationpolicy property you can set in the container that controls this. If you set to all, all the childrens will be created, but the initialization time will be longer

Good thought ... I tried that ... still won't animate. The Tree documentation states that " ... if a branch has over 20 children, it does not animate the first time it opens, for performance reasons."

Trying to figure out a way to override this ... any suggestions?

Thanks!

Well usually bad designs are overwrited with better designs ... consider not having more than 20 children at the same time

Unfortunately, I'm stuck with the constrains of the current database. I'll post something if I have an epiphany ...

Short story: I was asked to convert huge datagrids samples to Flex, with thousands of columns. Flex datagrid is poor in performance, and at some point it stuck. I was forced to use a list with a special renderer to show the whole stuff, no workarounds, just datagrid sucks (but probably new Spark doesn't? Didn't try)

I feel for you ... I've had to do the same thing.

Anybody know if there's a spark Tree on the horizon? Or point me to an open source one that addresses my problem ... it's worth a virtual beer (or any virtual beverage of your choice) ...
