I believe this is true. JabbyPanda told me the status of AdvancedDataGrid in bug JIRA. You will see that Adobe abandoned the maintenance of Data Visualization Components.

Flex Data Visualization Components:Advanced Data Grid

Before, we need to pay money to use Data Visualization Components. And many enterprise companies have still used those components.

I think Flex 4 is not ready for large projects and I believe it contains a lot of experimental elements. So Flex3 will be used in large projects for two years at least.
(you know, a large project needs a long term)

At March 11 2010, Adobe made those components a part of open source Flex SDK. It sounds good. But actually it isn't. They just abandoned the maintenance of Data Visualization Components and just leaves them to Flex community.

How irresponsible it is!

Adobe should find the consignment company which maintains Data Visualization Components. Don't just leave them to Flex community.
Most Flex developers who have high skill will not contributes the code with free. They are fixing bugs of Flex by client money.

Recently, I've had to customize the AdvancedDataGrid in a project. Then I've found these BASIC bugs.

AdvancedDataGrid doesn't scroll automatically on dragging
By pressing F2 key, non-editable cells turn to edit mode.
The moved data is not dragged data if selection is changed by arrow key / page up/down key on dragging
When we drag a editable cell, a wrong row is selected after we drop the row.
On Drag/Drop, ListEvent.CHANGE with wrong information is fired
When selectionMode is cell, ListEvent.CHANGE event is always fired at KeyDown though the selection is not changed.
After selectedIndices was updated, it can not be selected with ShiftKey
itemEditor focus is not in the right place
When I drags a row over AdvancedDataGrid header, drop indicator shows at the last visible row
it dispatches ListEvent.CHANGE by pressing F2/SPACE key on editable cell (renderer)
The copied row by drag&drop with Ctrl key is highlighted when mouse rolls over the original row.
The value of selectedCells are different between ctrl selection and shift selection.
Can't drop the row to the bottom
The dropped row is not selected after drag&drop
selection doesn't clear completely
the cell caret doesn't move on vertical scroll
some selected cells with Ctrl key is not cleared when I click a cell
ListEvent.CHANGE is always dispatched if selectionMode is singleCell
selection indicator doesn't clear completely on page down/up

Do you believe these so many bugs?!

Have you checked the committed source, Adobe?
Is there any quality management? Just believe developers. And the committed source is equal with real release!? Or because too many employees had been laid off? Or because of open source?

Even if Adobe has any excuse, this low quality is not permitted. Adobe, you better think real quality management and should develop flash quality management software instead of FlexUNIT and QTP.

Because the product is such a quality, Steven sniffs!!

In AIR 2.0 Beta 2, some API were moved to new package "air.net.*" and "air.desktop.*" which are included in aircore.swc.

Currently I'm working on a big financial project at a big international SI company of Shinagawa. The department is Solution Development Department 3 at 6F. If you know me and know this company, please say hello to me :D

This number is Google Analytics Report of my site in 2009.

2009 Google Analytics Report

The 138 coutries is 70% of the world. I think this is good number. Don't you think so?

Also "93,814 visitors" is good number, or not, what do you think?

In 2010, I'm thinking about making some contents (e.g. useful know-how and some sample sources) charged. Have you ever bought know-how and sample sources? How much can you pay for it?
