[flexcoders] Re: Flex 4 layout documentation for spark ActionScript components
Hi Alex, i coded a short example. http://www.box.net/shared/knmjmazcvv The zip file contains 3 files: HelloWorld.mxml (the application), MyComponent.as and MySkin.mxml. If you remove the comment in line 42 in MySkin.mxml, you'll notice that the measuring is done correctly, as far as i understand. Whereas the code without the additional invalidation call leads to missing calculations of the positioning. What i don't understand: which values should i expect when dealing with groups and why does the result differ. Best regards. --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: I may not be understanding your issue. I'm pretty sure our SkinnableContainers delegate their assigned layouts to the contentGroup because the contentGroup's measurements affect the size given to it by its parent and the eventual call to updateDisplayList. If you subclass updateDisplayList in the SkinnableComponent I don't see how the assigned layout will know that its measurement is not right. One way to encapsulate the measurement and layout logic together is to create a custom layout. I suppose you could also just override measure() in the component as well.

There is just one update of the measuring missing, which i don't understand. When a Group is using a BasicLayout contentWidth and contentHeight should be equal with width and height, if clipping is not enabled and no values for width or height are set explicitly. Or am i mistaken in this point?

I want to initialize the components in MXML and size and position the children in the component's (a component's skin) updateDisplayList, although this might be a bit of an uncommon approach. I was implementing the positioning via UIComponent.move, which i realized was the wrong approach. After just setting the x and y properties, i did some research and stumbled across the ILayoutElement and its methods like setLayoutBoundsPosition and corresponding methods to modify the skin's display list. But somehow the group, which contains the children, does not propagate its new size up to its parent. I use the updateComplete event to invalidate the group's size and force the layout to be calculated properly a last time. The view looks as expected. But i don't think that invalidating a component a last time after an updateComplete event was dispatched is wrong. Now, what is the right approach for the following task: implementing a skinnable component and a corresponding skin. The skin creates the skin parts in MXML in a Group (id=contentGroup) but the layout is calculated within the skin's updateDisplayList method. I only found one useful article on the web, which is not really a lot of information at all (http://www.adobe.com/devnet/flex/articles/spark_layouts_print.html).

I might be reading this the wrong way but in FILE_UPLOAD_ URL you should put

Re: [flexcoders] Blocking
You can load it with JavaScript synchronously, ExternalInterface is also synchronous, however, it is possible that you will run out of time and the application will crash because of that. Because, even though you can try-catch timeout error, if the function that produced the error won't exit, you will get another error that you cannot try-catch.

1. De-selecting build automatically, still builds automatically 2. Refactoring - it's total crap.

I have a checkbox that would trigger whether a combobox would use an
xmlListCollection of all Locations (xmllcAll) or an XMLListCollection of just a
subset of locations (xmllcSubset).
In the change event of my checkbox, I have defined:
private function checkBox1_change(e:Event) :void
{
if (e.currentTarget.selected == true)
{
comboBox1.dataProvider = xmllcAll;
}
else
{
comboBox1.dataProvider = xmllcSubset;
}
}
By default, the comboBox's default dataProvider is the xmllcSubset. When I
tick the checkbox, I expect that the data for the combobox should now map to
the data for the xmllcAll variable. The comboBox does not get the proper
values. Is there anything that I need to do to refresh the comboBox and make
the values that appear on the list those that were in the the proper
xmllistcollection?
Thanks.

[flexcoders] Best practice - remote calls from a flex library
I'm trying to figure out best practice for making remote calls to my server from components that are in a flex library. e.g. I have a postal code lookup component. This component will make require a user to enter a state, which will get all cities for that state (or counties, or metro areas, etc.). This requires a database call. Now rather than forcing the application that uses this component to make this call to the server then inject the resulting data results into the dataprovider for my postal code lookup component, I want the component to load this data. Is it best practice to have something like com.mywebsite.business that contains the remote calls for the library, then the component, when needed, will load that data? Just trying to get a few opinions on how everyone handles this. I have another library that contains most of my business logic (services, VOs, events) and one that contains my components (modified arraycollections, customized comboboxes), but wasn't sure about adding these items in. Any thoughts would be appreciated, Thanks,
Re: [flexcoders] Best practice - remote calls from a flex library
I'm afraid you won't find a solution that covers all cases. We at some point decided to not have any business / value objects and return the SQL data unparsed parse it on the client, of course not the other way, when sending the data. This may be really controversially to the best practices, but in our case performance matters more. Also, if you are building with AIR and using local database (SQLite), whereas security is not of concern, but the speed matters, then it's one case, once it requires roles, permissions etc, that's the other case. Also, we found that we can make more efficient serialization than AMF on our own, so, not really using value objects again. However, this may be important if the traffic matters more then the development speed / maintainability. Best. Oleg
Re: [flexcoders] Best practice - remote calls from a flex library
Looks more like you are trying to achieve inversion of control principle. Instead of the component calling invoking a method of an object, the object is *smart* enough to know when to invoke the call and provide data to the calling component. i think your application should do just fine regardless whether you apply IOC. There are certain trade offs as well - from a cleaner code and maintainability point of view. As much as I do in development, I only make the call to the database when necessary - regardless whether the call is from the component or the object. JIT - Just in time is more like it.

[flexcoders] DataGrid error when scrolling to last row and starting item edit
Hi, I have a subclass of the DataGrid, with two columns, each with its own renderer. One renderer has a button, which when clicked, starts item edit (consisting of a TextInput). Consistently, when there are too many rows for one pageful, scrolling down to the last row and starting item edit, results in this error: TypeError: Error #1010: A term is undefined and has no properties. at mx.controls::DataGrid/commitEditedItemPosition()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\controls\DataGrid.as:4064] at mx.controls::DataGrid/updateDisplayList()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\controls\DataGrid.as:1804] ... Any inputs on how to solve this greatly appreciated! Line 4064 of the DataGrid class is: var item:IListItemRenderer = actualContentHolder.listItems[actualRowIndex][actualColIndex];
[flexcoders] Re: Combobox in ItemEditor
Hi Alex,
thank you, I tried it using an id for the combobox, gives me an error
Access of possibly undefined property foo through a reference with static type
mx.containers:Grid
and there is also another problem, when I click on the column in the datagrid,
the itemeditor changes to a combobox with the default value to be the first one
in the dataprovider instead of the selected one
this didn't happen in the first case (first case I mean with out using the grid
and gridrow) but here, I get a warning uable to bind to property 'datafield'
on class 'object' (class is not an IEventDispatcher)
any suggestions
thank you

Here the itemeditorinstance is a grid so, probably its not able to convert to

I use the grid, as the rows are of variable height and the combobox looks
huge if the height of the row is more

[flexcoders] Re: Best practice - remote calls from a flex library
I guess it's a little bit of IOC. It's really based on environment as well, so we get the data from different places based upon where the code is deployed (dev, stg, prod, qa, etc). In some of our other apps, we have the application set up to get postal codes, but that then starts assuming the app knows a lot about what to get and where to get it, rather than the components doing that for themselves. I'll probably end up having some service calls within the library to get that information, but didn't know if someone had figured this out already. I guess the 3 ways are: 1. Service calls within the library that point to the same spot each time (not optimal should the server change as it has in the past) 2. Have the app get the data and pass that on to the components (forces tight coupling with app, and having knowledge about the components) 3. Use a build script to compile the mxml/as files and thus have the environment built in that way. (need to get antennae up and running...soon :) This way no matter where the file is deployed, it would get the data from the correct spot.) 4. Any other suggestions? :D --- In flexcoders@yahoogroups.com, Angelo Anolin angelo_ano...@... wrote: Looks more like you are trying to achieve inversion of control principle.

Yeah, I'm not really concerned about VOs vs queries, as that all depends on the situation. I'm really just trying to figure out how to get that information into the library without coupling the component to an app or if there's even anything bad about putting the service calls for getting the information within the library itself (other than environmental issues i.e. dev vs stg vs prod). --- In flexcoders@yahoogroups.com, Oleg Sivokon olegsivo...@... wrote: I'm afraid you won't find a solution that covers all cases.

Re: [flexcoders] Event before preinitialize
it's taking a couple of seconds to reach the preinitialize event. according to this slideshow http://www.slideshare.net/michael.labriola/dense-and-hot-360-flex slide 24, 25 etc there are a couple things going on that i don't need early on. so i'd like to check the contents of a shared object or session variable early on and redirect to a much lighter login page if i need to.

Re: [flexcoders] Event before preinitialize
That's what I'd like to do. So I added an event listener to the application preinitialized event like so: s:Application preinitialize=myHandler() / the problem is, in my application it takes a while to get to that event. so that's why I'm trying to find another event that happens sooner than that. it would be great to have systemManager, fontManager, resourceManager and styleManager creationComplete events so I can see what's taking so long in addition to redirecting if I need to.

Re: [flexcoders] Event before preinitialize
Hi Judah, AFAIK, you have 2 approaches to execute the code before preinitialize event is fired. 1) Mark you class with metadata [Mixin] and put the code in need into method public static function init(systemManager:ISystemManager): See HowTo create your developer ToolBox with Mixins blog article http://www.rialvalue.com/blog/2010/05/21/howto-create-your-developer-toolbox-with-mixins/ 2) Via custom preloader class you can execute the code before SystemManager.intialize() method executes, See How I (sort of) modified Flex’s SystemManager.initialize() method http://www.visible-form.com/blog/how-i-sort-of-modified-flexs-systemmanagerinitialize-method/ -- Best regards, Andriy Panas On 4 June 2010 06:57, dorkie dork from dorktown dorkiedorkfromdorkt...@gmail.com wrote: That's what I'd like to do.
