Javascript vs Flash based webUI

[sqpost]

Hi,
I have a web-application project which requires interactive User
Interfaces. It is more like a web based xml content editor. I have seen
a few javascript based text editors but not much flash based ones. I
dont have much experience on neither of the technologies so I have to
spent some time to develop my skills on them (your suggestions are
wellcome:) my questions are:

1. Is JavaScript and the today's internet users's enveronment
(browser-speed-security) mature enough to run a heavy javascript based
web application ?
2. I have the "sceptic feeling" that with Javascript, programmers have
very little control on runtime environment or javascript behaviours,
errors are not so predictable on client site. (Still I see lots of
websites with javascript and a yellow Error sign on my browsers left
bottom corner). Is it still quite complicated task to make the
javascript run properly on most of the users site (say 90%) without
complicated browser/version/DOM tricks and customisation?
3. Is Flash a better option for a interactive UI application? If so why
is it still just an "animation" technology?
4. Is it possible (and easy) to mix the Flash with other technologies
like Ajax or ASP.NET ? Is it possible (and available) to make
flash-based components (like special behaviour combo box, or new kind
of UI components) which can be used in an asp.net web application?

Thanks
Steve

IMO, yes it is.

Usually due to programming that wasn't written and/or tested for
cross-browser compatibility. Just because IE does it one way doesn't
mean that's the only/best/most used way.
Is it still quite complicated task to make the
javascript run properly on most of the users site (say 90%) without

I don't think so. Some would. It's mostly a matter of knowing what
you're trying to do and understanding the differences between browsers.
3. Is Flash a better option for a interactive UI application? If so why
is it still just an "animation" technology?
Dunno - Flash isn't my thing. You might want to try a broader-topic NG
for that question, perhaps alt.www.webmaster
4. Is it possible (and easy) to mix the Flash with other technologies
like Ajax or ASP.NET ?
Possible, I'm sure. Easy? You'd have to ask someone who does both.
Is it possible (and available) to make
flash-based components (like special behaviour combo box, or new kind

The flash-specific questions are best asked in a macromedia newsgroup,
I think.
Javascript should be able to do what you want, and I think you will
find it a bit more widely used (despite Macromedia's [bogus, IMO] claim
of 99% market penetration). Flash can probably do it, too. But there
are trade-offs either way.

Thanks for your reply Tony,
Actualy, I did post to macromedia.flash.actionscript as well but it
seems either noone knows the two technologies enough to give some
answers or noone is interested in :(
