Today I meet interesting problem.
I have an XmlDocument and do a lot of manipulations with elements.
It appears that when I do element.SelectNodes(xpath) and in xpath I have something like //value it does search in whole document and not in the element itself.
Surprised and confused. After all what I done in xml to find this bugfeature.

When focus goes away from visibility Flex doesn't scroll automatically. This helps.

And to selected and display the very last item in a grid use myGrid.scrollToIndex(data.length);

Reading about Visioning of Database also (Scripting Database from Command Line)

If you need to handle sorting on Date type column in DataGrid (in Flex) don't do that. It is much easier to do this.

As "not now" solution you may set sortable="false"
