[flexcoders] Flex 2 FDS pricing for clustered solution
Hello flexcodersI found no info on the Adobe site about pricing, from the threads I understood that FDS is priced 20K$ per CPU for unlimited concurrent amount of users. We are building the solution that will require support thousands of simultaneous users on the site and will require up to 100 application servers as we grow. I know that Adove guys are reading this list so I have a questions first of all to them and to those who have some relevant info about this- Is it true about pricing 20K$/per CPU for unlimited users?- Do you have some discounts policy for such cases as described above? - How much will it cost us to license FDS for 100 dual CPU servers?- Can we license only AMF gateway without any client pushes etc with discount?The problem is that we simply need amf gateway on that 100 servers and paying 4M$ just for gateway is too kewl as for me. I'd better develop one on my own :) We are investigating alternatives such as OpenAMF but we want to know the amount of money we need to spent on original Adobe solution.Thanks in advance for any comments.-- WBR, Mykola __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!

Re: [flexcoders] Re: FDB usage
Hi MaxI gave it some thought and I believe it is not that easy to do since you need a syntax analyzer for AS code in order to be able to watch variables and put breakpoints etc. So it is not just about finding any GDB compliant UI debugger and make it use FDB. That is why there are still no IDE for debugging Flex 1.5. I think that Flex 2 eclipse based debugger is somehting you are looking for but for Flex 2.0.

Re: [flexcoders] Uncaught exceptions in Flex 1.5
Ok Peter, no idea why you've been confused but... ActionScript specification has a notion of throwable objects, so saying that Exception is a bug of the AS2Lib is slightly incorrect. I'm relaizing that due to the size constraints of the player it might be good idea not to include exception handling in it, but once more again you can add this in the development version of the player and this should be extremely easy to do if the overal palyer's architecture is good enough, isn't it? My opinion is that without having proper error reporting it is impossible to build anything larger than hello-world presentations with a very good quality, so I'd warn people to treat Flex/Flash as a really serious platform unless this feature will be implemented. Flex Developers in my company mostly are very unhappy with the quality of the framework and the level of the support Adobe provide for the users, I'm not saying about paid support I'm saying about community support, feature requests, bugfixes, open source frameworks around Flex etc. I see no other way for developing the really good product other than involve the community into the development. It is the way lots of really cool stuff were developed for the last year and it is mostly ignored by Adobe. You have a great idea of RIA and a great high performant player, if you make a great product it will be an all win situation. The only way to make a great product is to make it more open to the contributing than it is now. IMHO but it is proven many times in Java world So do not just throw away comment from such crazy guys like me, Maxym, Sergey and lots more, all we want is to make the platform we are using better, and do trust me without responding to the real feedback from developers any technology will shortly become outdated. On 4/24/06, Peter Farland [EMAIL PROTECTED] wrote: Mykola, I'm slightly confused by your post in contrast to what Sergey and Stanislav originally said. I read Sergey's post as that he was having trouble with uncaught exceptions and had to add a lot of code to catch and possibly ignore such errors. I read your post to mean the opposite of this in that the uncaught exceptions were important at development time because if they were silently caught and ignored it would be hard to diagnose what the problem was. As Matt said, in general for our data services framework code we tend to not throw exceptions but instead funnel everything through a fault event mechanism. If you run into exceptions in our Flex framework code then it may be a bug and should be reported with a reproducible case or at the very least a stacktrace. If these exceptions are due to non-Flex framework code then either its a bug in that 3rd partycode or, as Matt suggested, the number of entry points that need to be checked can be reduced by centralizingthe calling code. Finally, the behavior of uncaught exceptions isn't determined by Flex - it's a feature of the Flash Player virtual machine and how ithandles ActionScript.

Re: [flexcoders] Re: Question to Adobe about Flex Framework 1.5 Code Quality
Ok,as a result we have a FlexCompiler servlet that has a memory leaks and kills application server periodically. It is absolutely a stop-ship bug but Adobe has not released new version of Flex 1.5 yet. As a result there is no stable version of Flex. Yeah I'm realizing that Flex is pretty far from being open source, I just cannot imagine how people can sell such poor product for the great price. About breaking code. It is absolutely not acceptable having releases once per year or even more like Flex does. Maybe I'm just from another world but I think being not open to the community like Adobe do is a way to produce the poor quality. Flex has great idea but no good expertise from the community. All the critics about Cairngorn, FlexUnit is just ignored however it is obvious that Flex need to have a strong community involved in development of the components and the architecture Look at Java community, great success stories of Spring, Jboss, Apache and tones of the other really HQ products. We get addicted to the good quality of the design, Not the 200+ UI classes extended from the IEventDispatcher.

Dirk, thanx I'm already using it but I want to enchance it a bit and need to be able to pass some parameters to it. Also I do not like undocumented features like the ones I'm asking in this thread about.. Its OK for open source where you can see sources but its not OK for commercial servers. BTW I've decompiled flashgateway.jar slightly (just for debug to put brakepoints) and found that the code quality is very poor. I'd refactor it much. For example in flashgateway.adapter.java.JavaAdapter protected Method getMethod(List parameters, String serviceName, String functionName, Class aClass) modifies 'parameters' within the method. It is a design bug since get methods must not do that :) since modification of the passed parameters as a side effect smells very bad I spent 2 hours debugging until I suggested that someone can modify that property in the method and I found that my suggestion is true after I decompile tha JavaAdapter and see the code.

Re: [flexcoders] Is Flex mature?
Hi Steven Thanks again for the comments. Lets stop the discussion about frameworks, my opinion about Core J2EE patterns etc because its a religious controversy. I will share my results when I'll be ready. The question of this topic was not Cairngorm or something else but: Is Flex mature enough now? What are our chances if we need to build huge RIA application in 7 month using Flex? I'd like to hear about project already completed or about to being completed by teams of at least 20 developers. Also we cannot rely on the Flex2 since it uses 8.5 player that will not be widespread by the moment we need to launch. WBR, MykolaOn 11/28/05, Steven Webster [EMAIL PROTECTED] wrote: Mykola, Totally agree but EJB was also first technology for enterprise development in Java and it worth us to be blind for a 5 years. EJB was the same overcomplicated that Cairngorm is and as far as I understand Cairngorm uses the same patterns and fully inspired by J2EE. EJB and Cairngorm have nothing in common; both are frameworks, one as you know is a (excuse the simplification) framework for object persistence, the other is a framework microarchitecture for RIA. That the EJB spec is overcomplicated does not mean that Cairngorm is, just because both can be called frameworks or both have reference to J2EE. Cairngorm does borrow heavily from the body of work that was performed with Core J2EE Patterns; however, it is not applying J2EE to Flex, it is recognising that many of the patterns that the Core J2EE pattern catalogue included, are patterns that can be applicable to RIA development with Flex (MXML and ActionScript). Note I say *can* be applied to RIA, not *must* be applied to RIA. There are many ways to skin a cat. Apologies to cat lovers. Insert annoying animal of your choice. do not repeat previous mistakes. You do not need to get things that complex like thy are now with Commands FrontControllers and other stuff. I think that's quite a bold statement. Perhaps you do not need them, and I absolutely agree that many many projects do not need Commands, Front Controllers or other stuff. However, I have worked on and with several projects that *have* benefited from these patterns and the architecture that the collaboration of these patterns introduced. Was this solution the *only* way we could have addressed the problems we faced ? Of course not ... There are as many different ways of doing these things as there are talented architects and developers that are now working with the technology. If you have your own framework that works for you, and if it addresses the problems that you face in your design, then you're correct not to use Cairngorm. Many other developers have done the same as you, and their implementations are not the worse for it. However, let's also accept that a great number of developers *have* benefited greatly from frameworks such as Cairngorm or ARP, have felt that these frameworks have introduced simplicity where complexity previously existed. These people do not think Cairngorm (or whatever other framework) is bad. Nor will they assert that the framework you are using instead is bad. Let's not continue this thread on the assertion that there will be one ultimately better than all the rest way of building all RIA upon Flex. Now I have a kind of framework that is much easier than Cairngorm and I'll try to share it with the community when it will pass internal sainity testing in our team (now guys are happy but lets wait more serious testing). I look forward to seeing it, and hope that it can be presented not as better than Cairngorm or simpler than Cairngorm but simply different to Cairngorm. In understanding what you tried to achieve with your approach, rather than what you don't like about other approaches, I think we'll all learn a lot more, no ? - No kickstart examples like Appfuse in Java Hopefully time wil bring them. Flex2 will drive a radically larger community. It is a huge problem cause when you need team development you need unittesting, framework, build strategy etc. And I'm sure that every team create it from scratch now. The idea is to publish some approach and evolve it to support and show best practices on it. Just to be clear, I know of teams of 30+ developers who are developing Flex applications based upon Cairngorm, who are actively embracing unit-testing, continuous integration, refactoring, and all manner of other agile practices. Certainly, the same team that brought you Cairngorm initially, has a great deal of experience in delivering projects using Agile methods, particuarly XP, with both Java, ActionScript 1.0, ActionScript 2.0 and most recently Flex 2 and ActionScript 3.0. The technology, and the choice of architectures upon the technology, have never impinged (any more than AWT, Swing, J2ME, JSP and _javascript_, etc have) upon our ability to deliver using agile methodologies. I guess the challenge here, is that many of
Re: [flexcoders] Is Flex mature?
Aldo, My alternative is one of the good old Java MVC frameworks: Struts, Spring or Webwork. I know that our user experience will sucks in this case but it is better than found that your application is too big in size or too slow or requires some unique plugin or all together :(. Also personally I'm very sceptic when it comes to the non open source technologies, but I must admit that Flex community is very strong. I still believe than Flex has a great future but I have some doubt that the time is come to build something serious on top of Flex.

Re: [flexcoders] Is Flex mature?
Hi Aldo Mmh, It's all about taking the better road...Let's start with a premise: Flex 1.5 CAN be used to develop mission critical applications ( evidence suggests this ). As can all of theframeworks you suggested. Very good news I'd like you to be right. Actually everything is possible the only difference is a price you pay to make things work in a proper way. Second, I would say that Flex has the following differentiatingfeatures in favor. See which apply to you: - Development will be faster I would not say so since it is very easy to find people familiar with Java MVC frameworks and also there are much better books in this area. Also you will 100% need lots of wokrarounds and facilities in Flex such as unittesting, i18n error handling, authentication that are already implemented in Java samples - Will force you to create a well defined services layer. You canevolve the presentation layer later I used to do this way so it is not a pros its just a reasonable thing. - You will gain RIA expertise that can be ported to Flex2 later ( orXAML or other eventually ) Agreed - The final user will be positively impressed ( assuming you do a good work ) Agreed but may have performance bugs :( - You will have many new tricks which will eventually give you morechoices around use cases Agreed again - One more tech under your belt Not a good argument from the point of business but let it be :). Actually technology is only an instrument and any technology can be easyli learned if you know concepts and the problems it solved. For me Flex was very easy since I knew _javascript_ verywelland lots of MVC Web frameworks, I believe the same with Laszlo. Then, write down the flaws ( or negative features ) which you alreadyidentified. Repeat the process for every other tech, then match by subject and fill in a comparison matrix. Try to quantify them.I have found that taking a cold minded economist's perspectivesometimes comes in handy. Specially when there are feelings involved.Getting someone else in the decision process might help, and keeping track of it is always a good way to CYA.It's all about choices, not perfect solutions, isn't it. YeahI alsowant our choice to be motivated from economist's perspective, that is why I've opened this thread. Notto say that RIA sucks, but to ask guys that have much more experience in it about does it economically motivated to build application on top of Flex or it is still academic technology as its examples are. I strongly believe that in some time RIAs will change our vision of internet and it is the future. Cross-browser virtual machine together with good API and enhanced user experience will be that features that will help to do it, just like Java changed our way of programming serverside applications.

Re: [flexcoders] Is Flex mature?
On a slightly different topic, the Core J2EE patterns— the book with the Sun logo splashed all over its cover— **mostly** documents "patterns" (used extremely loosely because I content that the only real patterns were those introduced by the classic GoF book) that were often fixes or work-arounds for missing functionality in the J2EE spec and/or container design flaws. This isn't meant to belittle the engineers that worked on the related J2EE specs, but merely that you have to start somewhere and there were gaps along the way— the core J2EE patterns helped plug the proverbial holes. Nothing to add. That is exactly what I think based on my experience. Spring, new persistency APIsand MVC frameworks has removed need of the Core J2EE patterns however I know lots of application were build on top of them. Without them EJB would goout of usagemuch earlier. So statement Cairngorm is based on the Core J2EE patterns does not impress me but rather make me think thatthere should exist some more lightweight approach:). However any approach is better than no approach at all.

[flexcoders] Is Flex mature?
Hello flexcoders. We are building a huge web application. Our product management want it to be RIA to produce the best user experience. We've choosen Flex as our client technology because it is the best on the market now. But I have a doubt that Flex is a mature technology suitable for enterprise development right now. Does anyone have completed some really big application using Flex, or about to complete? By really big application I mean about 100 of screens in terms of HTML. The problems I see in Flex now are (affects version 1.5) -poor support in IDEs comparing to JSP - poor component library comparing to the desktop and sources ofcomponents are closed to extension. For example to add button in DataGrid I have to use hacks (cell renderers) - poor support of debugging/profiling - Runtime errors are ignored and sometimes its quite hard to determine where is the bug - Poor frameworks. Cairnigorm is overcomplicated anddoes not fit agile development model due to the lack of unit testing approach - no i18n support on mxml level - No kickstart examples like Appfuse in Java - Async call model. Sure it is a great feature but it makes development more complicated Sure it is great to have a really cool alternative to the html and I believe in a year or 2 Flex will be one of the leading technologies in Web development. Macromedia is doing a great job together with Lazslo and sure Ajax. The question is if we have to launch our site in less than a year and site is really bigwhat are ourchances? -- Best Regards,Mykola -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com YAHOO!

Re: [flexcoders] Is Flex mature?
Hi Aldo, thanx for a very usefull comments. I'm sorry I have no much experience with Flex 2 since it is alpha now and will require Flash 8.5 plugin, thus will require most of users to download plugin. It is not a problem for a corporate sites but in our case it is a very big problem because we have to buiid site that is oriented on mass user and it will take about a year to get 90% of users use 8.5 player. However now our application is much faster on 8.5 plugin. About your comments: In Flex2 you will have an eclipse plugin ( which is more than enough for any J2EE developer ). Moreover, the SWF format is open, the MXML format is based on XML, and the standalone compiler can be integrated to any other third party IDE. It's just a matter of time till we have 3rd party IDEs showing up. Personaly I use FDT plugin for AS since it is the most mature and Java like (automatic imports, code completion, AS Docs and lots of other features) It does not support Mxml but the idea is to remove scripts from mxml so MXML is very easy in our framework not like the AS code BTW, Cell Renderer is not a hack, in the sense that it was meant to do just that. It is a documented feature. ( OTOH, it is not quite straightforward and suffers of the nuances of Flex 1.5 component development... ) I'd better like mx:Column to support internal tags like it is in Struts displaytag library. Since it is almost impossible to reuse cell renderers. The idea of component is that it is reusable component that can be easily tuned to suuport your requirements. Adding button to the row is a kind of tuning and must not require extra coding. That is my opinion but I guess most of the community will agree with me Flex2 runs on Flash8.5, which does support Runtime Error detection. I have found it to be amazingly useful and enhances my productivity dramatically. Agree 8.5 is much faster Cairngorm is the FIRST framework donated to the flex opensource community (yes, there is ARP, but it was born for Flash). If you have any contributions to make, I'm sure Steven and everyone else from Macromedia Consulting would be eager to listen and develop a new framework. I believe you can still influence on the new integrated development approach planned for Flex2. Just keep on your discussions on the subject alive. Totally agree but EJB was also first technology for enterprise development in Java and it worth us to be blind for a 5 years. EJB was the same overcomplicated that Cairngorm is and as far as I understand Cairngorm uses the same patterns and fully inspired by J2EE. So I just want Flex do not repeat previous mistakes. You do not need to get things that complex like thy are now with Commands FrontControllers and other stuff. Now I have a kind of framework that is much easier than Cairngorm and I'll try to share it with the community when it will pass internal sainity testing in our team (now guys are happy but lets wait more serious testing). - no i18n support on mxml level I believe Macromedia did not want to risk a strategy upfront, before realizing what the real requirements were... Could someone from macromedia develop on this? What is the state of things now? Will the new Cairngorm support it? will it be integrated into Flex2 later? IDE Support? You know, it is a critical common requirement ( every app nowadays is intlzed ) Again we've added it to our framework. But I see no reason why MM guys haven't done it themselves - No kickstart examples like Appfuse in Java Hopefully time wil bring them. Flex2 will drive a radically larger community. It is a huge problem cause when you need team development you need unittesting, framework, build strategy etc. And I'm sure that every team create it from scratch now. The idea is to publish some approach and evolve it to support and show best practices on it. Just like appfuse does in Java community. I guess we have to create our own appfuse Spring + Hibernate + Flex, maybe also Spring + Hibernate + Laszlo to have fully open source alternative. - Async call model. Sure it is a great feature but it makes development more complicated Ok. This is the way things work. It is not that hard to get used to this sort of programming once you gain some practice. Again, I hope new frameworks provide easier/simpler ways of doing this. I'm not saying it is hard to get used to it but some things are almost impossible in such model. For example unittesting. I managed to write unitests for our approach but it was very hard and if your approach evolves test need to be greatly changed not like it is with the sync calls. The question is if we have to launch our site in less than a year and site is really big what are our chances? Tricky question. How about going for Flex2? It is s much better in many many ways that it makes sense to start developing and, when the final release hits the streets, make the appropriate changes ( if any ). It is a very big risk and also we have to consider the plugin problem since most

Re: [flexcoders] Java Pojo to AS pojo with ant
Hi Jim, For my current project I've implemented ant codegeneration for Generate actionscript pojos from java pojos Generate client-side actionscript business delegate from that same interface (for cairngorm framework) I cannot share the code since it is project specific but I can share the idea. The implementation itself is very easy if you are familiar with Java. I'm using XDoclet2 as a generating tool. The templates are written in Velocity but they are very simple. To determine which classes to generate I'm using IValueObject empty interface. I do not use EJB I use Spring with Hibernate and thus I generate delegates for my Java services that are placed in a Spring context. I have a convention that all my service interfaces called ISomeNameManager and I convert them to the SomeNameDelegate with the same package. That is all. If you know exactly what you need to generate it will take you a couple of days to get introduced into XDoclet and create your tool. Good luck.

Re: [flexcoders] Re: Java Pojo to AS pojo with ant
Yeah Dave, totally agree XDoclet and EJB sucks. Now we do not use XDoclet for java any more, we have Java 5.0 annotations. But I've found XDoclet2 suitable for generating interface between Java and Flex. People in flex team are really hapy that they do not have to maintain their Delegates and ValueObjects any more, since they are maintained dynamically. I'm a Java programer myself and I found that Flex is much more closer to Java developers familiar with web mvc frameworks than to the Flash developers. Also it is very funny to read about Flex EJB integration samples since EJB is deader than dead. It's strange but the only stuff I've found about Spring2Flex is SpringBeanAdapter library. It would be interesting to have a poll about what Java server techology people use for a backend. I will be very surprised if it will be EJB.

Re: [flexcoders] Re: Java Pojo to AS pojo with ant
Frank Lets be honest. I'm a guy that used to the Open Source Frameworks because the guys developing them are honest. They want only money for support, while the monsters that vote for EJB want to sell their IDEs and their application servers that supports that crappy heavy technology. It is not honest to tell that By far the current most popular form of persistence frameworks is the EJB 2.0 standard look at the any recruiting site to see what technologies are most wanted to be familiar by Java developers. EJB has about 15% and as far as I know that 15% are support of the old projects. Actually now the only thing that remains from J2EE is servlets and JMS for everything else we have Spring, Hibernate and other frameworks. Look at the any Java community site, EJB is dead. EJB2.0 is the worst technology I've ever known and even Sun now recognize it. And however EJB 3.0 is pretty like Hibernate I'd better use Hibernate with Spring than it. The same features but I can run it on Tomcat that is much liter than any EJB3.0 compliant app server. Spring Hibernate and AOP makes EJB dead!!! And great thanx to them. I do not need XDoclet any more, I can run unittests without Cactus I can deploy my application anywhere I do not need crappy EJB deployment descriptors, and I'm happy with it. -- Best Regards, Mykola On 11/21/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I think we all have to realize that all of our declarations on this topic are relative to our own experiences. That being said, if you use simple procedural JSPs, and servlets to expose DB backends using JDBC, then you might say EJB is dead. On the other side of the coin, if you do large scale, enterprise wide development, EJB is a life saver. Take persistence frameworks as an example...what are the alternatives outside of proprietary, non-standard COTS products? By far the current most popular form of persistence frameworks is the EJB 2.0 standard.This allows Container Managed Persistence, in which the application server manages the persistence for the developers, allowing them to concentrate on coding business logic instead of implementation specifics. Prior to EJB 2.0, the specification mandated remote interfaces and had no way to express relationships between objects. Both of these problems harmed performance, but they were fixed in EJB 2.0.Today CMP ships with all J2EE EJB 2.0 compliant application servers, thus it has a huge advantage over the rest of the marketplace due to the ubiquitous nature of the platform. Truthfully, there are many analysts whom (after reviewing the initial CMP and EJB spec) developed their own forms of persistence frameworks, and 2.0 did little to persuade them that things had changed radically for them to migrate away from their ingrained technologies. Thankfully the World of IT developers realized the deficiencies of previous persistence models and/or the hard sell in introducing a proprietary in house persistence platform to (rightfully) wary IT management groups at conservative publicly traded firms. What is required is an official java standard for persistence, and that is exactly what JSR 220 a part of the Java community process for standardization is. The Java consortium feels that by getting the entire Java community behind one standard Java persistence API, they will simplify the now-confusing, expensive and risky development of J2EE and J2SE applications using data persistence. During the specification member voting in August of this year, all present firms (Apple, Apache, IBM, BEA, JBOSS, HP, SAP, Oracle et all) votedon thespecification with such epiphanic comments such as: ?We believe JSR-220 will have great impact on the Java enterprise eco-system and will give productivity back to the developers.? ?JBOSS Inc. This new architecture provides a standard way to transparently persist plain Java objects. It is designed to work in multiple tiers of enterprise architecture, including J2SE, Web tier, and Application Servers, allowing it to be used for both the Web-based RFP and client-side java apps. This standard is an amalgamation of both CMP, which is for persisting distributed components built specifically to the entity bean component API, and JDO, which is geared towards local, rich object models not tied to any particular API. Developers can choose between these technologies by evaluating their requirements (persistent components or persistent objects). With both the freely available open-source persistence, and the maturing of the common, and now ubiquitous EJB model, it is highly suggested thatEJB isin for its' glory days. As this new SUN EJB 3.0 persistence framework is an extension of both EJB 2.0 CMP and the existing JDO API, the adoption of this new technology is an easy one for most Java developers working in common J2EE services architectures, for the initial exposure has already occurred. My opinion is that EJB is far from dead, one only has to look at the voting members for the
Re: [flexcoders] Re: Cairngorm is bad?
Anatole, I do not agree that it is a big problem in refactoring serverside code. Sure if you have no unit tests for RIA client you will not be able to detect that something broken when you change server interface. But in agile methodology that is most popular now you always have to have tests. And it is not impossible to do them for RIA client. Another thing that can help you is code generation. In our application we completely generate all Flex2Java interaction code (Business delegates for all java services and value objects), also we are trying to use strong typing as much as it is possible. So if you change server interface your RIA code will not compile in most cases. I agreed with you that bright people can work without frameworks but the code they will produce will not be quite maintainable. One of the main benefits of the frameworks is that makes code to be more clean for other people who knows that framework, however it raise some bounds for developers. Also I think that any serious project should be built using single approach. By approach I mean coding conventions, framework, and style of framework usage. Each framework can be used in multiple ways but to succeed you have to choose your own. I did so many times and in most cases we deliver stuff in time. -- Best Regards, MykolaOn 11/17/05, Anatole Tartakovsky [EMAIL PROTECTED] wrote: Mykola, I just want to clarify the point I was making about the refactoring and non-heterogenic environment. There is a huge difference between RIA and desktop application. It is called distributed non-heterogenic application.Refactoring theback-end Java code will not cause compilation notifications of missing/changed fields/methods in UI - they have to be found via global search and (with larger apps)through testing - and can easily slip into production, especially if done in maintenance phase. The same applies to changes in UI - very easy to get out of synchronization with back-end. Here is simplier example for desktop application developers. Let us say you do changes to non-heterogenic piece of application - SQL table used by application - changing column names and datatypes. Compiler (unless it is integrated with pre-compiler/code generator) is not going to catch those and prompt you that your queries are no longer correct. You can start getting random errors based on overruns of the buffers due to field length, etc. While programming is definetly fun, retesting large application after each change is definetly not. Writing test cases to anticipate future enhancements is not possible, adding ones along the change is not a reliable solution but rather desparate measure to plug the obvious hole. Iam aware of 2 approaches to reduce the impact of refactoring (while hopefully reducing coding as well): 1. usage of higher-level model objects encapsulating communications as well - i.e. super dataProviders that are aware of retrieval/update methods, maintain state, provide diagnostics andcan be submitted as a part of biggertransaction - just few features to be delt within any application. Such models can also greatly simplify coding of datagrids, forms and other databound controls 2. use code generators to be included as a part of build process. You can produce proxy objects that can facilitate strong type checking in either java of flex. They can improve performance of the software execution as guesswork is taken out of both client and flashgateway software. You can also generate UI resources so initial form painting is less time consuming. Iuse both approaches - actually one on the top of the other - to reduce amount of manual code. That drives application into using high-level objects instead of framework - and I personally like it. However I would say for one person who uses these approaches there are 10 people using frameworks. It come down to the project management - small teams of highly trained specialists vs uniformly trained in framework large development teams with predicatble (while long) development schedule/replaceable resources. If you foresee the lifecycle of the project to be completed via reducing the team toward the retaining the better technology peopleof the team and insuring the quality across the modules (and company budget allows for that) then the framework-less approach is the way to go. If you anticipate to retain maintenance crew of the least creative people that would prefer to do spot fixing then low-level code and framework might be better choice. Here is very simple article on abstractions that is also applicable to refactoring: http://www.joelonsoftware.com/articles/LeakyAbstractions.html Towardthe end, there is Joel's estimate what using code generators or frameworks amounts to: The law of leaky abstractions means that whenever somebody comes up with a wizzy new code-generation tool that is supposed to make us all ever-so-efficient, you hear a lot of people

Omar This is exactly what I mean you just have to learn how to refactor and not getting panic when you need it. Actually I'm not agree with Anatole that Refactoring of Flex applications is no fun refactoring is always fun and without is you will finally produce crappy software. Another thing I will never agree that model cant be static. Static is always bad, in 90% cases you will have to refactor it if you have a big application. To explane why static is bad lets see the simple example. you have a list of the order items and you want to implement viewing item content in the popup window (not modal). How will you do it when your model is static? when you open two popups they both will contain the same model. That is the problem. I do not see great difference between developing desktop applications and RIAs but as far as I aware in desktop applications model is never static (Eclipse and lots of other examples and recomendations). Sure for helloworld you can make is static but don't be surprised when you faced the problem while your application growth. -- Best Regards, Mykola On 11/16/05, Omar Ramos [EMAIL PROTECTED] wrote: Hi guys, Why not use the apropiate use when the situation merits it. If in your application you have a component that doesn't share it's model with the rest of the application then make it self contained and use the Delegates directly. If in the future you need to use it's model in other view's then just refactor it into a command. Please correct me if am wrong.

[flexcoders] DataGrid and paging
Hello Flexcoders I have a very simple question. As I found from http://livedocs.macromedia.com/flex/15/asdocs_en/mx/controls/DataGrid.html The DataGrid control provides the following features: Columns of different widths or identical fixed widthsColumns that the user can resize at runtime Optional customizable column and row headersAbility to use a custom cell renderer for any column to display data other than text Multiple modes of selection (row, column, cell, and edit), and selection events Support for paging through dataSupport for drag-and-drop operations. How does paging supported. I havent found any attributes in the tag, is it hidden functionality or just someone's dream? -- Best Regards,Mykola -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com YAHOO!

Re: [flexcoders] Re: Cairngorm is bad?
Good point Renaun, but how often do you need model to be shared across views that are backed by different mxmls? Even if you need it you can access one view from another, you can create some more general ViewHelper in this case that will contain that model. I'm my project 90% cases are just dummy calls to the server and displaying the results. If I'll need something that does not fit this concept and makes viewhelper very complex I can always refactor, but why should I start having in mind that I'm writing something very complex. My principle is use the simplest reasonable way that works. If it works for JSF, Struts, Webwork, Tapestry then why it does not work for RIA, only because client has more logic? Maybe cause I have no DnD in Java and some effects but all the rest seems to be the same. Anyway I'm glad that people realize that this approach can work. All I want is just not to do the sings more complex than they are. Refactoring will help if I'm wrong, but in most cases it will not be required. Mykola PaliyenkoSenior Software Engineer at Sonopia On 11/15/05, Renaun Erickson [EMAIL PROTECTED] wrote: The code example fit Mykola's arguments well, which I see as a case for a component that self contains everything. The Model, ViewHelper, and Command for these specific components would never be reused outside the component it self. Is there a need for this? Could be, but a lot of times Models run across multiple Views hence the need for more hefty patterns. For example you have one component that is the form to update a User (UserFormView), self containing all the ViewHelper, Model, and Command in the component is much easier then 5 different files. This is probably perfectly fine if the UserFormView component is truly self contained. But most applications require a lot of reuse and coupling is not so distinct and sometimes not so predictable. Some of the different view points depend on the way the Application are conceived and developed. A server business logic driven application like Mykola's case below might warrant strict self contained components. The Use Case driven Cairngorm methodology creates more robust components that are unaware of each other (excuse me for my broad statement here). Where I start to see self contained components break down is where the Model should be used across multiple Views. It nice to have a command setup a Collection of data that is bound across multiple views, and then to change you logic of when it gets loaded is really simple. You dont have to worry about all the places the Collection is used, all you have to worry about is the asynchronous of the Command call. I believe there is some room for discussion on the specific uses of self contained components and maybe some ways of integrating both ideas into Cairngorm. Of course with Flex 2 and the Data Services handling CRUD functions we'll have lots to discuss in the future.

[flexcoders] Cairngorm is bad?
Dear Flexcoders. I want to start here discussion about development enterprise applications using Flex. Our company has choosen Cairngorm as a framework to do it, but I believe it has some drawbacks My comments are here: http://jroller.com/page/mickolka?entry=cairngorm_is_bad I'm new to Flex but not new to the ActionScript and JavaScript, also I know lots of Java Web MVC frameworks so I have a vision about how framework should look like to make your project succeed.
