Log4x is a toolkit to assist in the development and runtime monitoring and debugging of applications built with Macromedia Flex. Based on and designed to integrate with Log4j, effectively the most popular logging framework ever developed, Log4x provides the Flex developer with a best-of-breed solution for instrumenting and logging their Flex based RIAs.Log4x takes advantage the Flex web services model, and can be intricately controlled by the developer on a per-application basis during development as well as by administrators in production. Integrating seamlessly with Log4j, Log4x provides a similar programming model making it intuitive for enterprise developers with Log4j experience. Log4x is being released under a community source license free of charge to all licensed Flex users. Features include: - Integrated logging between user experience and server layers. No other logging framework to date lets you bring together every tier of your enterprise flex application. - Ability to assign not only pre-set categories (INFO, DEBUG, WARN, ERROR) but also arbitrary logical application name spaces such as shopping cart, system, navigation, etc. - Logging levels are completely dynamic and can be enabled and disabled in real-time without having to ever recompile your Flex application. - Configurable batching with thresholds reduces network traffic and allows you to configure rules such as don't log unless an error occurs, then log the all steps that lead up to that error. - Based on industry

RE: [flexcoders] StringValidator and required fields
You can't have bindings in Validators, so the compiler is parsing
required={usePurchaseOrder.selected} to either true or false - and
it looks
like true from what you're saying. It'd be good if the compiler helper
a bit
more here, but it doesn't.
I was hoping that wouldn't be the case. Is there some architectural
reason why bindings don't apply to Validators? I couldn't find anything
in the docs about why this would be the case.
We don't think Cairngorm store has any bindings on validators - please
let us
know if it does.
No, it doesn't. I modified the store and apparently tried to be too
clever.
For what you're wanting to do, you're best bet will be to drop into
ActionScript
and change your validators at runtime.
Okay, will do that -- thanks for the information.

RE: [flexcoders] StringValidator and required fields
For what you're wanting to do, you're best bet will be to drop into
ActionScript and change your validators at runtime.
I've been working on this trying to figure out the best way to handle
it. The compiler nicely informs me that id tags aren't supported on
validators, so it appears setting the required property on a validator
isn't directly possible.
The only way I can determine is that I should be calling the validator's
disable method, eg:
http://livedocs.macromedia.com/flex/15/asdocs_en/mx/validators/Validator
.html#disable
So I modified the PaymentInformation.mxml to have:
mx:Model id=paymentInformationModel
usepurchaseorder{ usePurchaseOrder.selected }/usepurchaseorder
purchaseordernumber{ purchaseOrderNumber.text
}/purchaseordernumber
... etc ...
/mx:Model
mx:StringValidator
field=paymentInformationModel.purchaseordernumber
requiredFieldError=Please enter your purchase order number. /
Then, in CheckoutViewHelper.as, I modified it to have:
public function validateCheckOutForm() : Boolean
{
var validStructures : Number = 0;
var structuresToBeValidated : Number = 2;
// manually set required for non-binding validators
if (view.paymentInformationComp.usePurchaseOrder.selected)
{
mx.validators.Validator.enable(view,
paymentInformationModel.purchaseordernumber);
}
else
{
mx.validators.Validator.disable(view,
paymentInformationModel.purchaseordernumber);
}
... etc ...
}
However, this doesn't seem to work. I've tried passing in
purchaseOrderNumber and other variations to the disable and enable
methods, but it still shows up as being a required field.
I hope I'm missing something obvious -- my next step would be to use a
generic Validator with a custom validate() function, which all seems
rather messy.
Thanks,
Blake

[flexcoders] StringValidator and required fields
I've been playing around with validators and seem to have
encountered a behavior which is unexpected. Here's a sample of what I'm
doing:
---
[snip...]
mx:Model
id="paymentInformationModel" usepurchaseorder{
usePurchaseOrder.selected }/usepurchaseorder
purchaseordernumber{ purchaseOrderNumber.text
}/purchaseordernumber/mx:Model
mx:StringValidator
field="paymentInformationModel.purchaseordernumber"
required="{usePurchaseOrder.selected}" /
mx:Form
width="100%"mx:FormHeading label="Purchase
Order" /
mx:FormItem label="Pay using
purchase order"
required="false"
mx:CheckBox id="usePurchaseOrder" label=""/
/mx:FormItem
mx:FormItem label="Purchase Order Number"
required="{usePurchaseOrder.selected}"
enabled="{usePurchaseOrder.selected}"mx:TextInput
id="purchaseOrderNumber" width="100" maxChars="50" /
/mx:FormItem/mx:Form
[...snip]
--
(This
is modified from the Cairngorm store and uses the Validator.isStructureValid
call in the same way.)
This
displays correctly -- the user clicks the checkbox to use a purchase order and
the field becomes enabled and displays an asterisk beside it. But if the
user leaves it unchecked, then upon submitting the form it still thinks the
field is required. The telling part is that if I change the
StringValidator to have required="false" instead of
required="{usePurchaseOrder.selected}" then it correctly sees it as not
required.
What
am I missing here?
Thanks,
Blake

RE: [flexcoders] ColumnChart with logarithmic Y axis?
I'll see if that's workable. I'm pulling the data from an HTTPService result and using it to drill down to other figures so I don't want to alter the original data, and data binding works so cleanly for the charting -- I assume using this method I'll need to take the result and parse it out to an array of Objects first, then bind that array to the chart? For the next release, perhaps instead of or in addition to a LogAxis object, would it make sense to have an attribute called scale which you could set as scale=linear or scale=logarithmic, etc. for quick implementations?

Not officially possible, but you might be able to make it work by: - convert your values into logarithmic values using Math.log. - specify the interval property on your vertical axis to be 1. - use a label function on your verticalAxisRenderer to convert the labels on the axis to Math.pow(10,value); I think that would work.

RE: [flexcoders] ColumnChart with logarithmic Y axis?
I suppose, but this:
LinearAxis scale=logarithmic /
Feels a little bit oxymoronic, don't you think?
Sure, that example does! :)
Doing it with a separate LogAxis would require, at a minimum, this
code:
LineChart
veritcalAxis
LogAxis /
/verticalAxis
series
...
/series
/LineChart
That doesn't seem like it's too much overhead, no?
I was thinking more along the lines of:
mx:verticalAxis scale={customScale} ...
Then you could change the scale type on the fly should that need ever
arise.

RE: [flexcoders] ColumnChart with logarithmic Y axis?
Ah, I see. The problem is, mx:verticalAxis is the name of a property, not an object. MXML doesn't allow you to set properties on properties...you need to set the property to an object, then set a property of the object. ... You can still change the scale dynamically at runtime: myChart.verticalAxis = new LinearAxis(); myChart.verticalAxis = new LogAxis(); Got it, makes sense now.

RE: [flexcoders] Passing Models into MXML components...
I ran into this as well. The ugly way around it is to move the code
from the externally referenced file into the main file. So in your
case, that would be put the dspTravelProfile.mxml code into index.mxml.
However, for anything more than a small app, that's clearly
unacceptable. However, given that it's not able to find certain
properties, perhaps it's possible to give Flex some hints on where
employeeModel is being defined so that it's able to resolve references
across different files?

/mx:Script
mx:FormItem label=First Name:
mx:Label text={employeeModel.firstName}/
/mx:FormItem
When I first save/change the physical mxml and then run, i get this
message in the compiler:
Changes to unknown property, firstName will not be detected.
-THEN-
I hit refresh again, and it goes away? Is this just a polite
exception? and how do you pass down a byReference as a variable into
other components? (if its possible)

RE: [flexcoders] Updating datagrid using dynamic combo boxes
I seem to have solved my own problem. In the HTTPService definitions, I
was defining a result=purchaseService.send() call to refresh the grid.
Given that the combo boxes won't be updating except for the first time,
I've removed the result event and that seems to have done the trick.

Subject: [flexcoders] Updating datagrid using dynamic combo boxes
Hi,
In my application I have three combo boxes which act as a filter for a
datagrid. For example, I have:
Customer: Sales rep: Country:
_ _
|__|_||___|_| |___|_|
||
| ... Datagrid of customer purchases here ... |
The datagrid and all combo boxes are populated dynamically from
HTTPServices. When the user chooses a different country, for example, I
want to show all purchases from that country which also match the
currently selected customer and sales rep. So I've defined them as
such:
mx:ComboBox id=customer_combo change=purchaseService.send()
labelField=company_name
dataProvider={customerService.result.customers.customer}
/mx:ComboBox
The others are defined similarly. When my app initializes, I call:
customerService.send()
to populate the list of customers. The problem is that the change event
fires from the init routine, which then triggers the datagrid to
refresh. If all three combo boxes do this, then it's grabbing the data
three times from the server when it should only be doing one query.
After it initializes, it's not a problem, but I just want to avoid three
(possibly lengthy) database fetches at the start.
Any ideas on a cleaner way to do this? Perhaps it's possible to set the
change event for each after the initial send() completes or disable the
event until then? Or have I missed something totally obvious? :)
Thanks,
Blake

[flexcoders] Proper login window handling?
Hello,
I've build a
LoginWindow.mxml consisting of a mx:TitleWindow ... tag and related
code. I call this from my main application as such:
function
show_login():Void{var parent =
this;var isModal:Boolean = true;var
initObj = {};var login = PopUpManager.createPopUp(parent,
LoginWindow, isModal, initObj);login.parentObject =
this; // store a referenceto this
Applicationlogin.centerPopUp();}
So far so
good. When the user wants to login, I call a remote object withthe
username andpassword supplied by the userwhich queries a
databaseand passes the return value to a loginResult
function:
function
loginResult(result):Void{if (result ==
true){//switch to a
different panel in the
stack//parentObject.main_stack.selectedChild
=
parentObject.login_ok_panel;this.deletePopUp();}else{login_result.text
= "Sorry, your login details are
incorrect.";}}
And this works fine,
but it seems like a hack. I originally wanted to get this to work with
events. I setup an event handler on the "login" variable, the LoginWindow
fires off an event if the login is successful, and the application handles the
event and switches to a different panel in the stack. The problem is, this
didn't work. I could display an alert dialog, but the call to switch the
stack didn't execute. I assume this has something to do with how it's
being references (eg: event handlers are outside of the scope of the code in
which they're created) but after an hour of fiddling with broadcast handlers and
various other mechanisms, I couldn't seem to get main_stack to
update.
Is this the
only way to do it, is the event model cleaner, or is there a better methodology
for displaying modal dialogs like a login screen? Any pointers would be
appreciated.
Thanks,
Blake

RE: [flexcoders] Proper login window handling?
Ah, I found the problem. In the code below, I'm mistakingly using:
login.addEventListener(login_success,
new mx.utils.Delegate.create(this, showSuccessPanel));
Note the undesired new call when creating the delegate. Instead, it
should just be:
login.addEventListener(login_success,
mx.utils.Delegate.create(this, showSuccessPanel));
It works just fine now. I can't believe it was that simple.
Thanks for all the help!

I notice you are using selectedChild. It is possible that
login_ok_panel does not exist when you try to set the selectedChild.
ViewStack, by default uses deferred instantiation and does not create
the children until the first navigation. So if login_ok_panel has not
been instantiated, you cannot set selectedchild to it
Try selectedIndex instead.

I did try using a mx.utils.Delegate object but that didn't seem to work
either. Basically, I used:
// create login window, etc...
login.addEventListener(login_success,
new mx.utils.Delegate.create(this, showSuccessPanel));
and...
function showSuccessPanel():Void
{
login.deletePopUp();
main_stack.selectedChild = login_ok_panel;
}
In my LoginWindow file, if the username/password matched, I used:
dispatchEvent({type: login_success});
Still didn't work, unless I'm missing something obvious on how delegates
work. In the Developing Rich Clients book, page 367, I didn't see where
the setUpContextMenu was defined so perhaps there's an object being
passed I'm not aware of.
Thanks,
Blake
