[flexcoders] RIA: record insert best practices
I am wondering how people like to handle insertion of records in a RIAs for records that have a unique number field. Do people determine the unique id on the client side and create the record, or do they do that server side and return the new ID number back to the client. I prefer to do the MAX(id) check on the server in the database within a transaction, but I am realizing that doing it that way sort of forces me to block user interaction in the RIA until the ID is returned lest the user try to do something with that new record that I cannot support yet. Thoughts? Thank you.

Instead it ends up having a height of 612 and no scrollbar: (Former Adobe guy who worked on this stuff...) Set minWidth=0 on the VBox and now it'll be 100% of the outer Canvas. See my other post (a few days ago, in response to Ian Skinner) for an explanation. I'll try to explain this in more detail in a blog post.

Basically you have to call play() on the Sound object with the new
position as the argument.
Or you can use the SoundPlayer component:

[flexcoders] Re: RIA: record insert best practices
I'm no expert in Flex and RIA development but i have implemented creating the ID on the client using the createUUID to generate a GUID which by all practible means it will be globally unique. I found this to work well, plus it saves me ALL the hassle of generating a temporary ID and then get the real ID back after i post the results to the server. I'm generating many updates and a lot of times i'm updating parent child relatinships so if I don't have the real ID ahead of time it would be a large amount of work to get the real parent id then go through all the children and update the reference key based on the temporary key assigned to it on the client... it's even hard to explain in a sentance or two. Some pureist will think it's crazy to generate the key on the client, and I partly agree. But if it works, it works. You can also setup a method to request a block of unique IDS on from the server if you don't want to create it on the client itself. This keeps your ID generation centrally controlled but you still have the benefits of knowing your IDs for particular updates before sending them to the server. Some of it also depends on the ID types in your database. I actually am now using GUIDs in a SQL Server database and not using identity increment values. Even though my primary key indexes are a bit more fragmented i have not found a performance loss, just a bit larger database since i'm storing a 16bit id value instead of a 4 bit integer value. In my case i'm trying to build rapid applications and i generally have oen app and one database so generating IDs on the client is ok in my circumstance... maybe not the best for all. --Scott --- In flexcoders@yahoogroups.com, arieljake [EMAIL PROTECTED] wrote: I am wondering how people like to handle insertion of records in a RIAs for records that have a unique number field.

I find that when I move the mouse slowly across the images it behaves as expected. However if I move the mouse more quickly all the images end up getting zoomed. Use the rollOverEffect and rollOutEffect styles instead of triggering the zoom manually. The effect styles should take care of terminating any existing zoom effect and starting a new one when you roll over/out the image.

[flexcoders] Re: Scrubbing in a MP3-file
Hi, is there anybody who can explain how to give a mx:HSlider-component the ability to scrub in a MP3-file? I use a progress bar for this but you can easy adapt this to a HSlider. The progress bar visualizes the play position of the mp3 file. If a user clicks in the progress bar the song position will be set appropriately. Ok, you should already have a soundFactory:Sound and channel:SoundChannel. Set the new song position by handle the click event of the progress bar (or a similar event in the case of a HSlider): [...] var pausePosition:Number = (soundFactory.length / songProgressBar.width) * songProgressBar.mouseX; channel.stop(); channel = soundFactory.play(pausePosition); [...] hope this helps, René

[flexcoders] How to map Java abstract classes to AS3 VO?
We have an object model in Java which contains two base abstract classes from which the other classes extend. The model on Java/ Hibernate is what we desire, but we need to then mirror it on the Actionscript side to use Data Management. From what I understand Actionscript does not allow abstract classes however, is there a way to keep our classes in Java but hack the Actionscript to make the VO Data Management work? If it helps to see some code let me know and I can send you an example of what we are working on. Thanks, Kevin
[flexcoders] Re: How to map Java abstract classes to AS3 VO?
What I have done in similar circumstances is create concrete classes in AS which extend a common base and to connect those to my concrete classes in Java using the [RemoteClass(alias=x.y.z)]. I have then made use of interfaces in AS to give me a similar coding pattern in AS to Java. Keywords extends and implements both exist in AS, so even though I can't have abstract base classes in AS I can get to the same sort of pattern by implementing interfaces. You may wind up with a little more code than you would accept in Java but it works just as well. On the server side I use Spring to inject the class dependencies when needed. Another pattern I have employed on the client is to implement an interface in a separate .as file and include that file into classes which have common members and implement the interface. This goes some way to minimising the amount of code I end up with. Hope that helps. If I have understood you correctly, then I think that what you are doing fits inside the AS/Java model quite well as long as you are willing to compromise your coding purity very slightly in AS. I'd be interested to know whether you are using the Adobe Hibernate Assembler or using your own middle tier.

Can you send along some abridged fragments of your mx script that display this behaviour? It's a bit hard to say what's going on without being able to see some code.

Re: [flexcoders] How to map Java abstract classes to AS3 VO?
Hi Kevin, I'm not sure if what I'm about to say answers your question or not, but hopefully you might find it useful. In a current project that we're working on we need to mirror certain classes/data structures on both the server and client. There is no way to get around actually building this structure on both sides, so we did that. But then we extended JSON so that the server-side Java app could serialize and send any complex structure using the classes that we both understand. When the client receives this data it deserializes it automatically into the right structure. We made use of the dynamic class loader stuff. All we really did was add an extra property to every object, @ClassName, which is used during deserialization to create the appropriate class instance. Then using a predefined naming convention we slam the data into the class instances. Good luck on this project.

[flexcoders] Flash CS3 slow scrolling large scripts
Hi guys, Flash CS3 is annoyingly chuggy/slow when selecting multiple lines of code or scrolling through large scripts. And by large, I'm talking about 200 lines or so...so not *that* big. Short of using another editor, is there anything at all that I can do? Like unchecking some hidden Needlessy slow down the ActionScript window check box?

Re: [flexcoders] Re: How to map Java abstract classes to AS3 VO?
yes. We are using the HibernateAssembler which is another reason we
need to sync these VO's up as tight as possible so that we can let
the assembler do the work for us!
I found an example in the Actionscript 3.0 Design patterns book (see
below) which uses sudo-abstract classes to achieve the abstract
class goal. I am thinking we can use this approach to mirror the
existing abstract classes on the Java end with faked abstract
classes on the Actionscript end. I guess the real question is will
these map cleanly and allow the same data management that we get with
simple VO's.
I also don't know if using abstract classes in my VO (Transfer
Objects) is pushing the VO design pattern a little too far from it's
intended structure...
Thanks for your thoughts,
Kevin

[flexcoders] pulling in HTML content - looking for ideas
I need a more info panel that opens up when required at particular spots. I'm hoping to keep the more info content as one HTML doc (that can be edited/replaced by itself) without embedding the content into the flex app itself, with each section run off named #anchors. at least, that's how I'd do it if it wasn't a Flex app... The MSWord version of the HTML doc is 55+ pages total although each more info section is only a paragraph or two. I've been looking at the HTMLComponent.swc (http://www.judahfrangipane.com/blog/?p=104) but I don't think it's going to cut it for the long term. Meanwhile there's no native flex controls that will do this (unlike Apollo) so, can anyone suggest another way to do this? - I can't use a database - the more info content has to be separate from the swf and easily updatable. - it'll have to be HTML since it'll have simple mark-up and links to images - I'll still be able to bind each more info id/anchor to the flex app's own data any suggestions? thanx
[flexcoders] Re: RIA: record insert best practices
I'm no expert in Flex and RIA development but i have implemented creating the ID on the client using the createUUID to generate a GUID which by all practible means it will be globally unique. unique record identifiers are the domain of the data storage. IMHO, they should NEVER be generated on the client unless they are place holders to be thrown away at the first available opportunity and replaced by the internal data storage ones. and that's only out of desperation - if you have to generate Id's at all that is. the only time ID's need to be created are on new records. to be honest, it should STILL be the back-end systems job to generate it. sounds like you've got far too much business logic in the presentation layer and it's only a short step away from your system being a two-tiered application. Heck, why not go all the way and get Flex to generate the SQL for you to run on the database? (just overstating it to make a point). it comes down to abstraction, separation of concerns. what happens if you've been using UUID's of one format and change the format (ie to numeric Identities) or change databases? are you going to re-write the client's UUID generation code and re-compile just because you've changed from SQLServer to MySQL? My argument is that you shouldn't have to. Flex should keep it's nose out of where it doesn't belong. Some pureist will think it's crazy to generate the key on the client, and I partly agree. But if it works, it works. works for today yes. but what will those needing to expand the app in two years time think of this? In my case i'm trying to build rapid applications and i generally have oen app and one database so generating IDs on the client is ok in my circumstance... maybe not the best for all. ... apart from the fact that the data storage is part of the application, not tacked-on (and should be factored into the design)... the large majority of times you'll be able to get away with it but I can guarantee that some time in the future some of those apps will cause you to loose your gains. two-tier applications (like VB client-server apps) or apps with thin middle tiers work because the clients are tightly bound to the server. But Flex (and Apollo) are still fundamentally disconnected clients. application design is looking at the whole app holistically, not as a vehicle to cram as much as possible into the view. Flex can help build smart UI's that translate workflows to business processes, but IMHO Flex is not the whole application.
