Known Issues
For specific things see open tickets by milestone or you might find a solution in closed tickets.
Installation
IMP update site at http://download.eclipse.org/technology/imp/updates is slow and may become unresponsive. Due to the amount of related packages the likelihood of a failure is high. Huge amount of patience is required and you may have to retry multiple times. You are welcome to notify IMP team about it.
Flex sdk
compiler error unable to open './winFonts.ser' will raise when your eclipse path (thus the flex sdk path) has spaces in it #113
Assistance
AS3 Content Assistant is only working on package and class level and not in any way intelligent. I wait and see what imp will offer. Primitive assistance depends on an indexer, that i hope is functional in the announced imp build.
The mxml support does not include as3 script support in any way. But imp (thus the as3 editor) works with structured text editor so i think it might be possible in add that some day. If i know how that works it might as well be possible to include wst xml support for xml literals (with schema assistance) for the as3 editor.
Misc.
To configure the flex compiler use flex config files, axdt provides a wizard and simple auto completion for editing flex config files.
There is also no debug support yet, but it is possible with the fdb.jar. There is also no trace or logging option yet. The first step would be to implement a debug console. But the flash debug player might suffice at first.
But if you work on linux or favor eclipse over any other environment and don't want to spend cash for flexBuilder this project might be a good start. Installation is easy and documented. You can start coding Action Script 3 right away.
Eclipse 3.4 seems uncapable to update AXDT from 0.0.6.3 to 0.0.7, it's an Eclipse 3.4 intern problem that have not to do with AXDT. Use of Eclipse 3.5 is advised.
Eclipse Galileo may fail to launch after upgrading to Mac OS X 10.6.3, a behaviour caused by corrupt font cache. To work around this, follow the steps described in How to fix FDT (or any other Eclipse-based IDE) after Mac OS X 10.6.3 upgrade
Eclipse 3.6 (Helios) doesn't work with AXDT 0.0.7 (ticket #207). Use of Eclipse 3.5 is advised.
Outdated
Launch support works out of the box and is already usable.
Eclipse 3.4 has many problems with an outdated imp version (endless editor reconciler loop #67).
I might add added editor template support.
The new grammar is in effect since build 0.0.6.2 and supports unicode identifiers, xml and regex literals as well as virtual semicolon (newlines can work as semicolon).
