I apologize for even having to ask this question, but Adobe
does not seem to have either a web-based or a telephone-based
support center that can easily be accessed to ask this question.
I had been of the impression, since starting to experiment
with Flex development last summer, that I could freely use beta
versions of Flex Builder, but that eventually I would have to
decide whether or not to commit my company to the technology and
purchase licenses. On the other hand, without FlexBuilder, I also
thought I understood that I could commit my company to the
technology and successfully build and deploy the applications with
a little more effort, but not have to budget for expensive
development tools, by using the SDK libraries along with the
My previous version of mxmlc -- from an earlier Flex 3 beta
-- used to tell me, at each invocation, that it would expire
sometime late in 2008. My current version of mxmlc -- from Flex 3,
beta 3 -- tells me it will expire in a couple of months.
Have I made some huge mistake? Is there a simple, no-cost way
to use Flex with Actionscript? Why does the compiler have an
I don't recall the expiration policy for the previous Flex 3
Beta candidates, but the current Beta 3 will indeed expire; we
don't want the betas to last forever because they will be replaced
with offical releases. And as with Flex 2, the Flex 3 SDK (along
with the compiler) will be free, so an expiring compiler is nothing
to worry about.
