Re: [flexcoders] Modify Flex ComboBox DataProvider

[Alex Harui]

There’s a bug like that in Flex 3.5.  Older and newer versions don’t have that 
problem.

Re: [flexcoders] DataGrid error when scrolling to last row and starting item edit

Can you reproduce the problem with a  generic two-column DataGrid?

Re: [flexcoders] Event before preinitialize

[Andriy Panas]

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/

Re: [flexcoders] Event before preinitialize

[dorkie dork from dorktown]

That's what I'd like to do. So I added an event listener to the application
preinitialized event like so:



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.

It doesn't take long to check the contents of a shared object. Why not just

Re: [flexcoders] Event before preinitialize

 it's taking a couple of seconds to reach the preinitialize event.
according to this slideshow

there are a couple things going on that i don't need early on. so i'd like

[flexcoders] Re: Best practice - remote calls from a flex library

[gareth_arch]

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).

[flexcoders] Re: Best practice - remote calls from a flex library

[gareth_arch]

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

I don't think so. How early do you need it? Why isn't preinitialize early 
enough?

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

Re: [flexcoders] Best practice - remote calls from a flex library

[Angelo Anolin]

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] spark Panel titleBar equivalent

[bhaq1972]

In flex 3
I used do add buttons to MyPanel (extends mx.containers.Panel) titleBar.

var button:Button = new Button();
this.titleBar.addChild(button);


whats the equivalent to this in Spark?

one way i'm thinking of is using a basic layout, and positioning the buttons 
where I want. 

Just wanted to get an idea what approach others would take.

thanks

Re: [flexcoders] Re: Showing tooltip on the line

[Akshar Kaul]

i got a solution to this problem.

Make few changes in the drawtheline component.

Code :



http://www.adobe.com/2006/mxml"
width="400"

height="300" creationComplete="createLine()" borderColor="#00FF00"
borderStyle="solid" mouseMove="findTarget(event)">









Noe you can see the tool tip only for the line, not for the component :)

[flexcoders] Combobox in ItemEditor

[Goutham]

Hi,

I have a combobox in item editor in a datagrid. the combobox is populated with 
a dataprovider. All this works fine until I place this combobox inside a gird

working code


mxml code
-


 
  
 
  
 


actionscript code
-
object.data = ComboBox(event.currentTarget.itemEditorInstance).text;



problematic code
---


 
  
   

 
  
 

   
  
 


actionscript code
-
object.data = ComboBox(event.currentTarget.itemEditorInstance).text;


error in the action script code:
---
cannot convert _inlinecompone...@3780479 to mx.controls.ComboBox

Here the itemeditorinstance is a grid so, probably its not able to convert to 
combobox, how do we get the selected value of the combobox from the itemeditor ?

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

Thank you

[flexcoders] DateField problem

[Goutham]

Hi

I have a date stored in the database along with other details.
have a datagrid that shows all the details, clicking on a row pops up a 
titlewindow showing all the details of that row which can be editable as in a 
form.

the problem is, I am not able to fill the datefield from the value in the 
dataobject



as code:

tried
date.text = selectedRow.Date (date value from the database)

doesn't give any errors, but the datefield is not filled with the date

[flexcoders] When is there an update to flexbuilder that fixes these bugs on OSX

[Patrick]

1. De-selecting build automatically, still builds automatically
2. Refactoring - it's total crap. Sorry, but it screws up my project and misses 
all kinds of files while eclipse using java does this perfectly and fast, flex 
never gets this right
3. Copying and pasting multiple files into the project navigator, results in 
only the first one actually pastes into the project
4. Trying to report a bug throws an error "only one copy of firefox" can be 
launched at a time
5. modifying any static class takes the compiler forever to re-build

About about a 4.1 that solves these problems, how did this stuff get missed, 
does nobody at Adobe us a mac?

Re: [flexcoders] Blocking

[Oleg Sivokon]

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.

[flexcoders] Re: Flex 4 layout documentation for spark ActionScript components

[Florian]

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.
