[flexcoders] bug in setMonth() method?
Hi, all;
I'm working on making an app that will allow users to navigate from
one month to the next based on a start date and end date. I noticed
some interesting effects with the date object and days that fall
outside the 1-31 range (http://tinyurl.com/5qc46j), so I thought I'd
try something similar with months.
What I find is if the current month is 11 and you add 1 to it, you'll
actually wind up with a date that's not in the _next_ year, but one
in the year following.
Here's my code
public function makeDisplayedMonths(beginDate:Date, endDate:Date):void
{
var today:Date= new Date();
//set up date for loop
var parseDate:Date = beginDate;
//equalize parsedate and enddate
parseDate.setDate(1);
endDate.setDate(1);
while (parseDate = endDate) {
//update date
parseDate.setMonth(++parseDate.month);
trace(parseDate, endDate);
}
}
the trace is this
Tue Jul 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Fri Aug 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009

Wed Oct 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009

Mon Dec 1 00:00:00 GMT-0600 2008 Thu Jan 1 00:00:00 GMT-0600 2009
Fri Jan 1 00:00:00 GMT-0600 2010 Thu Jan 1 00:00:00 GMT-0600 2009
Note that it goes from Dec 1 2008 to Jan 1 2010, skipping 2009
altogether.
Obviously now I know this I can code around it, but it seems like it
should either throw an error that the month is out of range or just
keep incrementing.
Or have I missed something here?

The call to setMonth is superfluous (though personally I'd go with setDate(parseDate.month + 1)) but shouldn't actually be doing anything as in both above cases it's just being passed 0 and so should either cause a year rollover in both cases (which would be buggy but consistent) or in neither case, that it's different is a bit worrying.

--- In flexcoders@yahoogroups.com, gaurav1146 [EMAIL PROTECTED]
wrote:
Hi,
Thanks, I now get that addItem method was responsible for
triggering
the property change event. But I am not very clear what purpose does
it serve to have the dataProvider as Bindable. Based on your
example I
created a class Company and used an Arraycollection companyList to
display companies in the datagrid. It did not matter whether the
companyList was Bindable or not. All that was required was that the
name property of Company should be Bindable. Also for a list
containing Object the value of the datagrid was not updated if any
object property was changed irrespective of whether the list is
Bindable or not.
The thing is that if I do not set the dataprovider as
Bindable
I get a warning that Data Binding would not be able to detect
assignments to the dataProvider. I would be grateful if you could
point me to a scenario where declaring the dataProvider as Bindable
makes a difference. Would it be in cases like where I use something
like dataGrid2.dataProvider = {dataGrid1.dataProvider}.
The reason you get the warning when it is not bindable is you're
using the {} notation. That is specifically telling Flex to use a
bindable variable. If that variable weren't set prior to your
component's being drawn by the Framework, you would actually have an
empty datagrid--simply assigning a value to the dataProvider variable
would not populate the grid. One advantage of using a bindable
variable is that you don't have to worry about setting your
dataprovider explicitly at the right time to allow the Framework to
lay out and size your component correctly.
For instance, if your component that needs a dataProvider is a child
of a List component, then the first time the component is drawn, the
dataChange event will happen before that child exists. If you try to
set the dataProvider in code yourself, you might be tempted to try to
use the dataChange event to do that setting. But this won't work
because the child component hasn't been drawn.
So if you _don't_ use data binding, you need to really understand the
component lifecycle, since you'll need to assign the dataprovider to
the component yourself at the correct time, in an override of the
commitProperties() method. When you _do_ use dataBinding, simply
assigning a value (or a new value) to the variable triggers the
Framework to handle all of this for you.
What you're seeing with the ArrayCollection type is something
slightly different from data binding. In essence, this variable type
is specifically designed to talk to your dataGrid and stay in synch.
When you change something inside an ArrayCollection element, you can
get your dataProvider to update by calling the refresh() method on
the ArrayCollection. I think this works whether the ArrayCollection
itself is bindable or not. I'm a bit fuzzy on the details of that,
so I'll leave it to more experienced developers to flesh that out if
you need more info.

It would seem to me to be a poor UI where ENTER could have more than one meaning. Once there is a defaultButton, focusing any other Button enables ENTER handling on that button. That's the way it seems to work on Windows as well. The current button that will be activated on ENTER is given special highlighting so it will hopefully be apparent to the user what ENTER will do. I would recommend you choose one button that is the default for ENTER. Let's presume for the sake of argument that I have written something similar to a TabButtonBar, where I want to allow the user to tab through the buttons and press Enter to activate the highlighted button. What events would I want to listen for? If you're trying for accessibility, you need to be able to support keyboard-only navigation, as is hinted at in the Flex accessibility documentation. However, when you read the details of the accessibility documents, they talk about screen readers and ignore keyboard-only navigation.

[flexcoders] Component Broken
Hi, all;
I have a component that was working last week, but on Friday I had a

from the Windows Home Server backup. I thought my machine was back
100% from where it was, but I tried to run some Flex code that worked
last week and it is not working at all today.
The intent of the component is to read in an external xml file and
make it available as a data source in mxml.
package magnoliamultimedia
{
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;
import mx.collections.XMLListCollection;
[Bindable]
[DefaultProperty(xmlData)]

{
private var _request:URLRequest;
private var _path:String;
private var _xmlData:XMLListCollection;
public function XMLLoader(request:URLRequest=null)
{
super(request);
}
public function get path():String{
return _path;
}
public function set path(path:String):void{
_path = path;
_request = new URLRequest(_path);
this.addEventListener(Event.COMPLETE,
getURLResult, false, 0, true);
this.load(_request);
}
public function get xmlData():XMLListCollection{
return _xmlData;
}
private function getURLResult(e:Event):void{
var resultXML:XML = XML(this.data);
if (!_xmlData) {
_xmlData = new XMLListCollection
(resultXML.children());
} else {
_xmlData.source = resultXML.children
();
}
this.removeEventListener(Event.COMPLETE,
getURLResult);
}
}
}
Am I totally stoned in my recollection that this worked last week?
When the complete event fires, the data property is empty. I've
tried passing in a path of data/data.xml and moving the xml file to
the root and just using data.xml.
If anyone has any ideas, I'd greatly appreciate it.

perfectly, if
for any reason you don't think it will in the future, don't
hesitate to
tell me.
It sounds like you're expecting that your primary key will always be
the same as your index within the dataProvider. It won't! Assume
for instance that you insert 10 records into the table, then you
delete record 10. If your database is relational (let's hope it is),
likely there will be other tables with a foreign key that points to
the pk's in this table. So you can't reassign them (and I doubt the
db would let you anyway). Now, your table will have these UniqueID's:
0, 1, 2, 4, 5, 6, 7, 8, 9.
Instead, you should be looking at the relative position of the
returned record within the returned Array (data) that represents the
recordset. You can probably either add this as a property to each
array item in a loop or you may be able to use a subquery to add a
field that reflects the order of the item within the recordset. I'm
not sure if SQLLite will allow such a subquery, but it might be worth
a try.

[flexcoders] Which is more expensive: binding or setting
Hi, all; I have an itemRenderer based (sort of) on the checkBox Header Renderer described here: http://www.returnundefined.com/2006/11/creating-truly-reusable- renderers-with-classfactory I'm using BindingUtils to bind to a property of an object I am passing in. This property is the month number of the month that is currently being displayed in a calendar page so that days prior to the first of the month and after the last of the month can have a different styleName. However, I could probably add that to the code in commitProperties() that sets the styleName based on checking the month of the date property of the data variable against the month property that is set automagically through BindingUtils.bindProperty(). Alternatively, I could add more binding expressions to handle the other settings I'm doing in commitProperties. I'd like to develop a more uniform approach instead of the hodgepodge I have now. The question is, which will perform better, binding or setting in commitProperties()? Thanks; Amy

the List? Usually not, but sometimes, some other part of the UI is
binding to list.selectedItem.firstName which will still work as it
will
trigger on a change to selectedItem, but if you are editing items
in the
list and changing the firstName, then selectedItem will not change
and
other UI will not update.
If it doesn't need to be bindable, then I'd just call
invalidateProperties and stuff the fields in commitProperties. The
speed difference will probably not be obvious, but it should be less
code and run slightly faster and you won't get warnings. If the
data
object does need to bindable, then you might as well hook up with
binding if it is just a couple of bindings and the logic is
simple. If
you already have a commitProperties method, I would probably not use
binding and map the data object fields in commitProperties because
in
most cases, when the fields change in the person object, the entire
data
property gets re-assigned due to the way most lists update their
renderers.
OK, thanks :-). That's the direction I was thinking.

--- In flexcoders@yahoogroups.com, Jonathon Stierman [EMAIL PROTECTED] wrote: I would say it's more flexible to use the ClassFactory because you can dynamically set the properties in the ClassFactory. Simple example: Say you had an application that creates Squares - just simple rectangles on the screen. When the user presses a button, a new square pops up in a random location. If you used a hard-coded class to fill your Square class with pre-set instance data, you're locked in to your implementation. You'll have to write a new class if you wanted to give the user the option to create a RedSquare instead of a Square. It gets exponentially difficult if you have multiple things that might need to change as well: say color, size, border-thickness, etc. You'd have to make a new class (and then configure your application to use that new class!) for each property of Square. Not pretty! ... Also, when you're using a class as an ItemRenderer for a List based component, you don't have the luxury (AFAIK) of passing any properties to its constructor. So you can use a ClassFactory to set those properties in advance, then use the ClassFactory as the ItemRenderer. http://tinyurl.com/56hngy HTH; A

--- In flexcoders@yahoogroups.com, djohnson29 [EMAIL PROTECTED]

I have noticed some weird behaviour when working with XML vars and
XMLListCollections.
I have an xml variable that I am looping through using a for each
loop. I want to separate the xml into 2 seperate lists based on a
value so as I loop through, I am adding each xml node to 2 different
XmlListCollections.
Here is my code:
// myXML is an xml var declared elsewhere in the program
var xlc1:XMLListCollection = new XMLListCollection();
var xlc2:XMLListCollection = new XMLListCollection();
for each(var x:XML in myXML.MyNode){
if(x.NodeStatus == 0)
xlc1.addItem(x);
else if(x.NodeStatus == 1)
xlc2.addItem(x);
The problem is that the original xml var is getting modified.
Say for example that my original myXML variable contains 10 nodes,
and
there are 7 nodes that have a NodeStatus of 0 and 3 nodes that have
a
NodeStatus of 1. My 2 XMLListCollection vars contain 7, and 3 nodes
respectively as would be expected.
However, the original myXML var now contains 9 extra nodes! 19
nodes
in total. Flex somehow is adding all these nodes back onto the
original xml var except for 1 node from each of the categories. So
in
other words, the original XML var contains all the newly added nodes
minus 2.
Is this a bug in Flex? Shouldn't the XMLListCollection just contain
pointers back to the original XML var?
Someone correct me if I am wrong on this, but I believe that if you
add XML to an XMLListCollection, you're actually setting its source
to the XML object. So essentially both XMLListCollections are
pointing back to the same source and operating on it. I'm not sure
why not all of the nodes are getting added.
Try something like this:
private var xlc1:XMLListCollection=new XMLListCollection
(myXML.myNode);
private var xlc2:XMLListCollection=new XMLListCollection
(myXML.myNode);
private function filterForStatus0(item:XML):Boolean{
return item.NodeStatus==0;
}
private function filterForStatus1(item:XML):Boolean{
return item.NodeStatus==1;
}
public function init(){
xlc1.filterFunction = filterForStatus0;
xlc1.refresh();
xlc2.filterFunction = filterForStatus1;
xlc2.refresh();
}
You should now see the XMLListCollections properly populated.

It's early stages right now, but it seems to do everything I need, with API calls for moving from one page to another, zooming, scrolling, etc. The Pro edition is $80 and there's a server edition that has an automation API, letting you integrate conversion into your application. Very cool. Anyone facing this powerpoint to Flex problem should take a look to see if this meets your needs. I've had a quick look at print2flash and it looks good, but I think the problem for powerpoint conversion is the use of animation and transitions - something I don't think that print2flash can handle. I'm sure that conversion of static slides (via the print interface) would work fine. If you know different, let me know fast! Paul Connect (Breeze) does a pretty good translation of Powerpoint to Flash, but doesn't handle it well if you mix animation schemes with other animations. AFAIK, Connect is Flex under the skin, so surely it is possible. I know there was a guy in Italy rewriting Connect to be open source, Giorgio Natali, and I've seen him post occasionally on here. Maybe he will pop in with an opinion. If not, maybe a member of the engineering team could check with the Connect engineers and see if they can give you a hint. HTH; Amy

OK, I tried just sticking my TestRenderer component in the
Application file somewhere other than as an itemRenderer, and that
shows the red background (when the alpha is set to 1). So the
problem seems to be related to using the styled component as an
itemRenderer. Is there something special that the List component is
doing to its renderers that is preventing them from using the alpha
and color I've set in my CSS?

[flexcoders] How to remeasure itemRenderer
I want to add something to an itemRenderer in a List that will make it taller. I've set the List's variableRowHeight to true. However, when I set invalidateSize() in my click handler, the measure() method never happens. I've stepped through the code in the debugger, and narrowed it down to line 4487 (itemRendererToIndices protected function): if (!item || !(item.name in rowMap)) When that line runs, the invalidateSizeFlag on item (my renderer) suddenly goes to false. Any idea what's happening? What is the recommended way to remeasure an itemRenderer? Thanks; Amy

It's just a click handler on a canvas that contains a label. I would check to see if the validation of the size causes renderers to be recycled, defeating your addChild. Normally, you need to change a property somewhere so that any renderer that is recycled in for that data item will know to have that new child. Would the recycling be happening in the itemRendererToIndices call? Before the item.invalidateSizeFlag switches to false in that call, the item variable is com.magnoliamultimedia.views.TestRenderer (@4873479).

Sometimes clients can be very adamant about not allowing open source code of any kind, since they don't own the exclusive rights to that. But they often change their mind after you tell them how much money they will save if you don't have to reinvent what the open source community has already done. But it's important that you and the client have the same clear understanding about all this stuff. Part of the issue is that this might be the first big eLearning project I'm going to be doing wholly in Flex (if we win the bid). The eLearning community as a whole is very interested in Flex as a tool but people are hanging back until someone documents the way to solve the common problems. If I don't have to completely have to rewrite example code before making it available to the community, it will make it much easier for me to do my part in helping to document the process.

The original question was about taking the exact code that was created for one client and using it in another project (either for a client or as open source code for the community). I don't think there's much of a legal gray area here. Yes, everyone agrees that the knowledge and techniques that you gain while writing code are yours and can often be used in other projects. But that is not at all the same as saying it's ok to copy a class or chunks of code verbatim. Actually, the question was about signing a work for hire agreement and what other options there might be. It looks like the client is open to negotiation on this issue. After all, the client has already benefitted from code that I've shared with the community. Interestingly, the code I shared was created specifically for the presentation they attended. The client I have done most of my Flex work for doesn't really care about sharing snippits so long as I don't hand over his whole system.

You might need paddingRight=0 on VBox or HBox? I tried that already. The padding is inside the TileList. The TileList is the only thing that is that purple color. If I add padding to the vbox, you can see that there are empty pixels to the right of the TileList AND the TabBar. If you break in SystemManager.mouseDownHandler, the event.target should be the container or control that owns the pixels you clicked on. I added a click handler on the TileList as a shortcut to this. The target is the ListBaseContentHolder with the parent id = calendarDays.

That's one extra horizontalGap in there... possible the extra space you're seeing on the end? In several pixel-perfect layouts I've had to actually *not* use TileList because of the bug... though at the time I wasn't aware of the technique of monkey-patching (where if you create a class in the project that matches a class in the SDK the project class overwrites it), which would eliminate the need to modify the SDK source (which I generally avoid). I couldn't find a horizontalGap property on TileList, and trying to manually add a tag when the code hinting said no just resulted in a compiler error.

Because of the bindings and itemRenderers, its not possible to fiddle with your example directly. Oh, and you might want to take out the extra period on the right side of the screenshot link. :) paddingLeft and paddingRight are ignored. I tried setting them to some really high number just to see, and nothing happened. When I take off the 100%, it is a lot smaller on the left hand side of the screen (not using the full width of the tabBar).

If you use a repeater, this will happen automatically:
mx:Repeater dataProvider={yourArrayColl}
mx:TextBox id=MyTextBox /
/mx:Repeater
will give you an array of TextBoxes that you can access with
MyTextBox[0] - MyTextbox[n], where n is the number of items in your

You can also do this manually
var MyTextBox:Array;
for (i=0;i=numLoops;i++){
MyTextBox.push(new TextBox());

If the DP is an ArrayCollection, then just setting a property value on the item should not cause the repeater to re-render. (This is the case where you need to call itemUpdated() to force the refresh.) Amy's suggestion is sound. If you do not bind to the dataProvider, but rather assign the Repeater.dataProvider explicitly, then no changes to the DP will automatically cause the Repeater to re-render. My experience is that whenever the ArrayCollection's source changes, the repeater will update, but there doesn't seem to be so much of a cascading ripple effect--when you bind it seems to me like it refreshes way more times. So if you don't bind, the refresh might not be as visible. HTH; Amy

I've also tried setting a bindable variable in these places that sets the height and binding to that. My results are this: commitProperties--never gets to the full height updateDisplayList--stalls out (infinite loop?) measure--stalls out (infinite loop?) with bound variable, never reaches full height with setting the property directly Is there any way to use a ViewStack to simply change out the view without _having_ any height? Alternatively, is there a way to persuade it to wait until the children are sized to decide how big it is or to look at the size again when the children are done sizing? Thanks; Amy
