What's your strategy for WebService errors that aren't raised through fault handler?

Is there a way to underride the default functionality of
WebService.as? I can't find the source code in the SDK, so I'm
assuming this part of Flex isn't Open Source.
I find that using WebServices that there are a lot of errors
that potentially occur that I can't capture in the UI. Or, let me
rephrase that, that I haven't been able to figure out how to
capture in the UI.
For example, the following "Could not load WSDL" error
occurs. Now, I could probably devise a strategy around checking
that the connection is alive and such, but then I've seen other
errors that occur in the WebService base classes that are all fired
asyncronously.
Is there a way to add a default handler that capures these
types of errors? (They're not captures by FaultHandlers).
I can't have a UI that displays the big white box to end
users with a stack trace. Thanks.

I found out at FlexCOders, that when I'm not using the Debug
version of the Player that these errors should correctly propogate
to the Fault handler.

What is your strategy for form validation when using MVC pattern?

This is more of a general discussion topic and will not necessarily have a correct answer. I'm using some of the Flex validator components in order to do form validation, but it seems I'm always coming back to the same issue, which is that in the world of Flex, validation needs to be put in the view components since in order to show error messages you need to set the source property of the validator to an instance of a view component. This again in my case seems to lead to me duplicating the code for setting up my Validators into several views. But, in terms of the MVC pattern, I always thought that data validation should happen in the model, since whether or not a piece of data is valid might be depending on business rules, which again should be stored in the model. Also, this way you'd only need to write the validation rules once for all fields that contain the same type of information in your application.
So my question is, what strategies do you use when validating data and using an MVC framework? Do you create all the validators in the views and just duplicate the validator if the exact same rules are needed in some other view, or do you store the validators in the model and somehow reference them from the views, changing the source properties as needed? Or do you use some completely different strategy for validating forms and showing error messages to the user?

Thanks for your answer, JoshBeall. Just to clarify, you would basically create a subclass of e.g. TextInput and add the validation rules to that? Then you'd use your subclass when you need a textinput with validation?
Anyway, I ended up building sort of my own validation framework. Because the other issue I had with the standard validation was that it relies on inheritance instead of composition. Say I needed a TextInput to both check that it doesn't contain an empty string or just space characters, is between 4 and 100 characters long, and follows a certain pattern (e.g. allows only alphanumerical characters). With the Flex built in validators I would have to create a subclass or my own validator in order to meet all the requirements and if at some point I need another configuration (say just a length and pattern restriction) I would have to create another subclass which duplicates most of the rules, or I would have to build a lot of flags and conditional statements into that one subclass. With the framework I created I can just string together different rules using composition, and the filter classes themselves can be kept very simple since they only need to handle a single condition (check the string length for instance). E.g. below is the rule for my username:
library["user_name"] = new EmptyStringFilter( new StringLengthFilter(4,255, new RegExpFilter(/^[a-z0-9\-@\._]+$/i) ) );
<code>library</code> is a Dictionary that contains all my validation rules, and which resides in the model in a ValidationManager class. The framework calls a method <code>validate</code> on the stored filter references which goes through all the filters, the first filter to fail returns an error message and the validation fails:
(library["user_name"] as IValidationFilter).validate("testuser");
I only need to setup the rule once for each property I want to validate, regardless where in the app the validation needs to happen. The biggest plus of course that I can be sure the same rules are applied every time I need to validate e.g. a username.
The second part of the framework basically relies on Chris Callendar's great ErrorTipManager class and a custom subclass of spark.components.Panel (in my case it seemed like the reasonable place to put the code needed, although perhaps extending Form would be even better). ErrorTipManager allows you to force open a error tooltip on a target component easily. The subclass I've created basically allows me to just extend the class whenever I need a form and pass in an array of inputs that I want to validate in the creationComplete handler:
validatableInputs = [{source:productName, validateAs:"product_name"},
                     {source:unitWeight, validateAs:"unit_weight", dataField:"value"},
               {source:unitsPerBox, validateAs:"units_per_box", dataField:"value"},
                    {source:producer, validateAs:"producer"}];
The final step is to add a focusOut handler on the inputs that I want to validate if I want the validation to happen right away. The handler just calls a validateForm method, which in turn iterates through each of the inputs in the validatableInputs array, passing a reference of the input to a suitable validation rule in the model (a reference to the model has been injected into the view for this).
Having written this down I could probably improve the View side of things a bit, remove the dependency on the Panel component and make the API easier (have the framework wire up more of the boilerplate like adding listeners etc). But for now the code does what it needs to.

Well, it seems like most of you simply read the
various texts and try the vendors' examples. I'm
surprised that no one mentioned ever having bought a
prototype application from the onset. "bought"? What's that mean? You don't buy prototypes. You download evaluation versions, maybe.
I try to find sample code and tweak it to see the effects. Otherwise, I start writing small sample code an build on that.
I consider myself a reasonably competent core Java
programmer, but I had serious difficulty configuring
and merging its related technologies. There were so
many disjointed pieces of instructional information
that the additional research time really hurt our
budget severely. Not an uncommon thing, I'm sure. There's a lot of stuff. But don't bother learning all of it. Not in detail, at least. It's a good idea to familiarize yourself with the names of packages/libraries and what they do. But only really learn what you need to learn for what you need to do. The next project you will probably need other things, so you learn them then.
bsampieri,
I've setup Tomcat and tried the examples--in fact, I
normally follow tutorials for all products I hope to
use. Problem is, the examples and tutorials never
address my specific needs. So, I usually inch toward
my goal by spending weeks or months in forums to
continue where the tutorials leave off. Anything complex is going to not be there.... the trick is to identify pieces that you can pull out to build more complex apps. And the fact that JSP/servlets have the issue of being compounded by all the HTML/CSS/JS and HTTP protocol ... I don't want to say limitiations, exactly... Well, it just makes things more complex and harder to know what you need.
Perhaps you guys are much faster and smarter than
I...or you have a much bigger budget :)Probably not... on either account.

What's your strategy for learning Java technologies?

Or, in other words, how do YOU acquire knowledge that is necessary for implementing Java technologies?
After having spent one-and-a-half years developing an enterprise app, I've gained lots of knowledge about Java and some surface knowledge about its related technologies (JBoss, Hibernate, Ant, XDoclet, NetBeans and probably some others I can't think of at the moment).
I'm now realizing that -- although the standalone prototype version of my program is growing mature -- I've still got lots to learn for refactoring it to a web platform. For example, I 've done small test projects using Servlets, but haven't done any work with JSP (or HTML for that matter) yet.
Now, I'm sure I can learn JSP etc., but the questions I ask myself are: how long will it take?
It's a rhetorical question of course (I don't expect an answer from you, the reader) However, it's an important issue because the months or years I spend fumbling around learning these new technologies, are time I could otherwise spend on the business logic and functionality of my program.
So, how do you guys acquire knowledge of technologies? Official training perhaps? Or do you simply experiment until it works? Or do you rely on your company's knowledge base (e.g. someone in your company knows how it works)? Or do you get prototypes built from someone who already knows how it works?
I�m really curious about this and would appreciate your thoughts.
Thanks in advance,
P

what is your solution for getting public transportation in map? Actually my iphone is useless for me because it hasn't a public transportation map.

This has been a huge problem for me too. I was actually late to work yesterday and wanted to throw my phone out the window of the bus that I finally was able to find. I'm new to Portland, so this suddenly missing feature is particularly problematic. It really is so hard to avoid getting angry, I just can't believe they would eliminate a feature that people rely on so heavily. But anger doesn't do any good so I'm trying my hardest to stay calm and figure out an acceptable solution while Apple works to restore this feature - at least I pray to God that that's what they aim to do. Here are the apps that I've been trying, I'll try to explain how they work and maybe they will work for you. This is going to be a long post, but I'm hoping some people will find it helpful.
I'll start with the most obvious of all - adding Google Maps to your homescreen. Every time you launch the app you will get a diaologue prompting you to allow Google Mpas to use your location, and then you will be in an environment that looks similiar to what we are used to. It does not integrate with your contact list, so one workaround I've been using is going to my contacts and holding my finger on an address to copy it to the clipboard. Be aware that leaving this web app will lose whatever you're looking at and go back to the start, so best to do this before you launch it. You'll notice some strange behavior - for instance the drop down menu of suggested locations will apear and then quickly disaprear, so just ignore this. Often it will often unexpectadly scroll to the top for some reason when you're trying to do something towards the bottom. Haven't figured out a fix except for trying to not get flustered and doing things slowly and deliberately. It's not as quick as we're used to anyway so this is not hard to do. If you'd like to see any of the suggested routes on a map you can do this by clicking the small 'Map View' link. Just be aware that you can only do this once or you will have to type in your starting an ending points again, as there is no way to go back to the list you were just looking at once you are in map view. One thing that I have found helpful about the Google maps method is when looking at a route, whether in list or map view, you can see the stop ID right there, which is helpful if your city has a way to check real-time arrivals. For instance here in Portland you can text this stop ID to a certain number and immediately receive real-time arrivals.
The app I've been using most is called 'Transit'. It's pretty beautiful aesthetically, and the UI is simpler than anything else I've come across, which is convenient for a task that you want to accomplish as quickly as possible so you can put away your phone and be on your way. When you first launch it you're presented with three bus routes that stop near your current location. It tells you which direction the route is headed and in how many minutes the next bus is scheduled to arrive. This is helpful if you are familiar with that particular busline, otherwise there's no indication of where the line will take you. Upon clicking a line, you're presented with three buttons (again, loving the simplicity). One reverses the direction of that same busline. One expands the list of times so you can quicly see all the arrival times for that bus route at that particular stop for the entire day. The other takes you to map view and quickly displays the location of this stop. And here's the best feature of all (!!), it shows you the busline as a blue line and every single stop is marked with a circle. You can click on a circle and it displays the expected arrival time at that stop. This is all very helpful in some circumstances, but of course it does not let you type in a destination and have it build a route for you, and if you'll be transferring to another line this will not help you at all. To accomplish this you press the arrow in the lower left where you can type in a starting point, ending point, and an arrival/departure time. And this DOES reference your contact list. It will then allow you to quickly switch between three routes that it selects. It also searches Maps (actually it says 'Powered by Foursquare' for landmarks/establishments. For instance if I type in 'sushi', I'm presented with a handful of sushi joints in my area. There is a bug in this app where sometimes the 'Route' button is missing and you can only resolve this by leaving the app and quitting the process in the multitasking trail. When it builds your route, you can click on any point of transfer and it will tell you what time that bus/train is leaving. There is no list view, but personally I never found list view very helpful anyway. I know some people will disagree though.
Now I'll talk about HopStop. This is a kind of clunky interface unfortunately, and also has ads which I can't stand. It is able to reference your contact list. My least favorite thing about this app is the list it gives you is so excessively long-winded it's hilarious. Every single stop along the route is listed in this list view, so you'll be scrolling through literally dozens of pages of useless information like 'Pass such-and-such - 1 min. Pass such-and-such - 1 min. Pass such and such - 2 min.' Oh well. The good news is on this insanely long list, it indicates when you are supposed to do something other than sit patiently in your seat by having an icon to the left of that instruction - either a person walking or a bus number. When you switch to list view unfortunately it no longer displays departure times, so you'll have to be switching betwen maps and list view. One great feature of this app is it lets you save routes to your favorite list. It also lets you find bus stops and quickly see what bus lines hit those stops. I can't stand the flashing advertisements, so I avoid using this at all costs.
On to 'City Maps'. Again, the first thing you will see is a short list of bus lines that hit the stop nearest to you. Tap on one and it shows you the next three departures in either direction, as well as the distance between your current location and the stop in question. This app also searches for restaurants and such, but takes this feature on step further. Here when I type in 'sushi' and select a restaurant, I'm brought to a page that links to the Yelp, Foursquare, and Facebook pages associated with it - even has a link that takes you directly to the menu if Foursquare has it. Awesome feature, right?? Tap on 'Map' and it immediately displays the location and an option to build a few routes. It always displays the walking route below the bus lines to give you a sense of how long it would take (even if it's a two hour walk). Clicking on a bus route on this list takes you to list view. Unfortunately this also displays a deluge of pointess turns that only the bus driver need worry about, but it's not as bad as HopStop. There's an optional feature where it can display Google Street View images right in this list view, if you think that could be helpful. With one tap it quickly switches to a very aesthetically pleasig map view. There's an update button that lets you immediately refresh directions, edit starting/ending points, or give it new directions altogether.
I'm sure in just a moment someone will come along and say something insulting about how we're blowing things out of proportion. I guess that's just the nature of trolls - a lot of people find being angry on forums while hiding behind their screen names cathartic for obvious reasons. Let's all of us just do our best to ignore these people and keep this discussion diplomatic and oriented towards helpful solutions. I know none of us want to give up our beloved iPhones, I'm only considering it as a last resort.
