ColdExt Wiki and Getting Started Tutorial

Having a bunch of custom tags and an XML dictionary for CFEclipse is one thing, but knowing how to use them is another! So last night I began working on every developer's favourite task... documentation :P

The ColdExt Wiki is now enabled on RIAForge and I have started out with baby steps by writing a Getting Started Tutorial which covers the absolute basic requirements of getting up and running with ColdExt.

I have a number of pages and tutorials planned for the wiki (some of which I have already made notes of on the wiki home page) and will get around to adding them as soon as I can. If anyone would like to help out with documentation (rofl!) or start a discussion about what documentation is needed the ColdExt Forums could be a good place to do it. I am open to suggestions!

The next release of ColdExt will very much be about better documentation and demos, in addition to more tags and enhancements of course :)


P.S. Does anybody know if it's possible to turn off WikiTerms on RIAForge? At the least I think a special token like __NOTERMS__ would be very useful.

Justin, please hit me up via email to discuss the Ext license for ColdExt.

Thanks

Just an update: the Ext licensing info has been added to the downloadable package on RIAForge.

Justin - one thing that might help some other folks is to turn off CF Debugging when running the Ext ajax stuff. I couldn't figure out why i couldn't get the demos to populate like the ones you have here.

@Steve: That's a good point, thanks for posting here publicly. I got the same feedback from someone else as well, so I have added cfsetting to the top of those files to turn off debugging output when sending back Ajax responses (I haven't commited it to SVN just yet though).

I'll make a note on the Wiki to remind folks to be aware of debug output issues when developing with Ajax.

Is coldext project still under dev or not? its long time no news from your end.
# Posted By Neil | 6/5/08 6:03 PM
@Neil, Yes it is still under development. There is new code in SVN and activity on the Forums on RIAForge. I was hoping to release beta 2 before Scotch on the Rocks but its not quite ready yet :) If you need anything in particular please feel free to request it on RIAForge.

Hi Justin,
im very excited about your extJS-Project.
Theres one thing i struggle with:
When using ComboBox, how do i set an inital Value to the Form when editing a Record in a CRUD application?
Do i have to set this within a listener in the jsonStore tag or the comboBox tag?

@Daniel: I'm not 100% sure of the best way to handle it but there are a couple of threads on the Ext JS Forums that might help. I guess most people add an onload listener to the store and use setValue() to set the value on the comboBox:

http://extjs.com/forum/showthread.php?t=11703

It seems silly that there isn't a nicer way to handle the defaults though. There is a setValue() and setRawValue() method that you can use after a component has been created, but no way of setting the "hidden" value using the constructor config options (which is the way ColdExt creates the components!).

Hey, I've tried to make an implementation of the ext "Portal" in coldExt. I think it's working, but probably far from a best practice implementation of the framework. Drop me a line if you'd like the bits to review.
# Posted By Dylan Miyake | 6/20/08 3:56 PM
Dylan,

i was also a bit insecure about best practice implementation with coldext, not least because i'm new to extJS aswell. But in ht end i was surprised about the flexibility coldext offers me and how coldext alows me to do things in different way.

Any more Details about your review?
# Posted By Daniel | 6/21/08 4:19 AM
Dylan sent me the Portal demo and it works like a charm. I'll be posting more on user extensions and tags in the coming days.
# Posted By Justin Carter | 6/21/08 9:42 AM
Justin, I have some working examples as well that you could put out there for people. Let me know if you need them.

I can help with documentation too if you like. It will give me a chance to give something back, since your library has helped me out quite a bit on a couple of projects. :-)
