RE: [flexcoders] Re: Data grid with check box... How to get value
Title: Message
Joe.
Part
of the Custom Cell Render Spec are four attributes that are available to the
Cell Renderer. They are:
owner
- the row the cell renderer instance is in.
listOwner - thecontainer (data grid, list box, etc)the row is
in
getDataLabel - function that will give you the column name the cell
renderer is mapped to
getCellIndex - function that returnsan object/structure/hash map of
itemIndex (row), column index (pos in column array) and one other piece which I
forget.
So,
using this (they must be declared and are case sensitive to the spelling above)
you can either dynamically get to the value of the current cell or static get to
the value of a cell in that row. Here are some examples assuming you are mapping
to the clickEvent of the checkbox that is in your cell
renderer.
function onValueChanged() :
Void{var item =
this.listOwner.dataProvider[getCellIndex().itemIndex];item[this.getDataLabel()]
= checkbox.selected;}
or
function onValueChanged() :
Void{var item =
this.listOwner.dataProvider[getCellIndex().itemIndex];item['myGoofyColumn']
= checkbox.selected;}
Best.

Re: Data grid with check box... How to get value
The
data grid is populated from a data provider. It displays about 20 rows.
When I click on one of the check box I
would like to be able to get a value from one of the cells in that row.
The data grid is a MXML component and the
check box is from a cell rendering action scripting file.

[flexcoders] Data Grid/Cell Renderers Rendering Issue
All. Has anyone experienced the following (or something similar to it): We have a Data Grid with a height of 400. It has four columns, all but one have custom cell renderer. The Row height is 50 per row (defined in the dg tag). The data grid displays this fine originally but we found that row two (well second visible row) disappears if the number of rows is greater then what can be displayed in the 400 height. Thanks.

This file should work on JRun 4 as that application server is more lenient in its parsing of web.xml deployment descriptors. Other application servers may enforce the DTD specified order of each config section, for example, WebSphere expects servlets to become servlet-mappings, etc. This file takes this order into account and as a result is a little longer than it could be for JRun because the configuration sections have to be separated for CFMX 7, CFMX 7-Embedded-Flex and Flex 1.5. Another item to consider for other application servers is that each config element might need a unique id attribute. I'm not sure which application servers require this, but note that the Flex 1.5 config sections do not have unique id attributes and thus these would have to be added if the application server required it. The co-existance of ColdFusion MX 7 and Flex 1.5 is made possible due to several factors. Firstly, since CFMX 7 contains some portions of Flex to support its reporting and flash forms features, unique servlet names and servlet mappings had to be chosen to avoid collisions. Secondly, the two applications store the majority of there classes in their own directories and locate classes with a custom bootstrap classloader. The bootstrap classloaders allow each application to guarantee that their versions of common APIs, such as Apache Commons, Log4J, and XML Parsing APIs, are used rather than those shipped with each application server or user web application. The CFMX 7 bootstrap classloader classpath is specified by the cf.class.path context-param. Typically all CFMX specific libraries live in various directories under /WEB-INF/cfusion The Flex 1.5 bootstrap classloader classpath is specified by the flex.class.path context-param. Typically all Flex specific libraries live at /WEB-INF/flex/jars There are exceptions to this, however... application features that must run in the current web application classpath (such as tag libs used in JSP pages or Flex RemoteObject that needs to locate user defined classes) typically are contained in libraries in /WEB-INF/lib. -- web-app id=macromedia_coldfusion display-nameMacromedia Coldfusion MX and Macromedia Flex 1.5/display-name descriptionMacromedia Coldfusion MX 7 merged with Macromedia Flex 1.5/description !-- CFMX 7 Context Params -- context-param id=macromedia_context_1 param-namecftags/param-name param-value/WEB-INF/cftags/param-value descriptionPath to search for built-in tags.

Cairngorm .99 should have the ability to unregister view
helpers from the ViewLocator so when this is released you
will need to unregister the View in the destruction sequence
of the popup. In the mean time there are these options (may
be more out there):
Alistair released a patch for Cairngorm some months ago to address this; the
patch will be part of the forthcoming 0.99 release:
The URL on Yahoogroups is:
http://groups.yahoo.com/group/flexcoders/message/6148
Here's the gist of the email:
public function initialized( view : Object, id : String ) : Void
{
this.view = view;
this.id = id;
ViewLocator.getInstance().register( id, this );
view.addEventListener( unload, Delegate.create( this, unregisterView
) );
}
private function unregisterView() : Void
{
ViewLocator.getInstance().unregister( id );
}
private var id : String;
private var view : Object;
Add that to the ViewHelper base-class, and it gives you a method that allows
you to unregister the view; the motivation for this was people that were
using ViewHelper inside Popup windows; when the popup window was destroyed
with deletePopUp() it was deleting the view, but keeping the ViewHelper
reference - so we now ask people to explicitly unregister views in popups
when they are destroyed.
Hope that helps in the interim.
Best,
Steven

RE: [flexcoders] Re: Popup only works once
The issue is that each time the Popup opens, the ViewHelper attempts to
register itself to the ViewLocator. The framework has a rule that a
ViewHelper must be unique in its 'handle' (done by the ViewLocator checking
if the View Name is already registered to it) otherwise it raises and Error.
(Code can be seen in the ViewLocator.as file).
Cairngorm .99 should have the ability to unregister view helpers from the
ViewLocator so when this is released you will need to unregister the View in
the destruction sequence of the popup. In the mean time there are these
options (may be more out there):
1. Modify the Cairngorm framework by not throwing an error in the View
Locator if the Name is already registered to it. (Not saying this is the
best option, just saying this is one way to do it)
2. Open up the popup window (child) without a view helper or a view helper
that doesn't have a name on it (if you are looking for code abstraction).
Have the child raise events that the parent can listen to. When the event is
raised have the parent broadcast the event (to the command) and have your
Commands talk to the parent to get the necessary information from the child
window.
I have found there to be value have the child popup simply raise events that
the parent (the mxml file that created the popup) is listening for in
several situations. Esp in any sort of master/detail relationship (address
of a user for example).
Hope this helps.

RE: [flexcoders] beginners question about sending data to custom flex components
Title: Message
I
could be wrong, but from my experience I found that binding with functions
doesn't work if there are no arguments that are passed into the function that
Flex can watch.
So.
myClass.myFunc() - Flex doesn't know that it should recheck the
function
myClass.myFunc( myClass.att1 ) - only recalls function on change to
myClass.att1
I
havn't tried goofing around with what happens if class raises change events like

what I want to do is the
following:
myCustomSWC
myDataToBeUsed="{myActionscriptClass.getData();}" /
the problem is that the function is not
executed but simply passed as a string to the component. Another problem is
that the actionscript class may not have initialised yet so the function
would not work at all.
does anyone have a suggestion on how to do this
???
thanks very much !!!

A rundown of them all:
Who's on here?
-
function showProps(o:Object):Void
{
for(var p in o)
{
trace(-);
trace(p + : + o[p]);
trace(typeof: + typeof(o[p]));
trace(is a String: + (o[p] instanceof String));

trace(is a Array: + (o[p] instanceof Array));
trace(is a Boolean: + (o[p] instanceof Boolean));
trace(is a Date: + (o[p] instanceof Date));
}
}
Obviously there are more data types.
You know the type (not recommended):
var val:String = o[p];
You coerce the type (recommended, but expect weird results):
var val:MyClass = MyClass(o[p]);
Keep in mind, the above works differently since some intrinsic datatypes
have special constructors; String(something) actually converts it to a
String, and Date's overloaded with a few different ways of making them.
...obviously, interfaces are typically the best way, since you can typecast
'em (I think, I did it with a CollectionItr):
var myA:Iterator = Interator(reallyARecordSet);
Or something to that effect.

RE: [flexcoders] Cairngorm Question.
Title: Message
The
way Cairngorm current architects the ViewHelper is that itrequires
eachViewHelper to register itself to the ViewLocator under a unique name.
Therefore if you are attaching theview dynamically in a repeater and using
the samevalue in the 'name' attributefor the ViewHelpers
thenthe ViewLoactor will throw an error.
One
approach to your solution is to have the each of your views bubble up its
methods to the parent view that the repeater exists in.
For
example (in code babble).
MyMainView.mxml
mx:script
public activeChild : MovieClip = null;
function parentHandleMethod(evt)
{
// store current child view to
local var
activeChild =
evt.target'
// do server
call
}
/ms:script
mx:repeater

Hi
all,
I am using the
Cairngorm plataform but had a small question. How can I use the viewhelper
technique when I attach view dynamicaly? For example I have a mxml component
and put a view helper attached to it and use this component on a repeater and
5 instances are made. When I call the getViewHelper method which of those 5
reference will it give me? Any help would be apreaciated.

RE: [flexcoders] Proof of Concept - (help with Flex Setup)
This is possible and mirrors one of the environments I had to use in the past. In the mx:RemoteObject tag there is an attribute called 'endpoint' where you can point your mxml remote object calls to. Find the server name where flex is running and do 'servername:port\amfgateway' for java or the servlet mapping to flash remoting. If you are going to use the Flex server to call you java classes make sure the classes are available to the Flex server and that you have the whitelist configured correctly. -Original Message- From: Libby Chantel [mailto:[EMAIL PROTECTED] Sent: Thursday, March 31, 2005 2:10 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Proof of Concept - (help with Flex Setup) I am writing a Flex proof of concept app that accesses existing Java programs on the back end.

RE: [flexcoders] Cairngorm Question.
Title: Message
Well.
My thought is 'Who would know what child needed the work done?' The view
locator's need to have the view helper name be unique is so that it can locate
the view. A command has to be 100% sure what view towork with to get the
data to properly make the call out to the server. Therefore my thought is that
the safer bet would be to have the command talk to the parent to either a) get
the data or b) get the name of the child.
Anyway, those are just my thoughts to why I would approach the situation
the way I outlined. My judgment of clean has a lot to do with the ability to
maintain the application and as much as possible keeping the interdepancy
between my view files as possible. Loose coupling.

The
way Cairngorm current architects the ViewHelper is that itrequires
eachViewHelper to register itself to the ViewLocator under a unique
name. Therefore if you are attaching theview dynamically in a repeater
and using the samevalue in the 'name' attributefor the ViewHelpers
thenthe ViewLoactor will throw an error.
One
approach to your solution is to have the each of your views bubble up its
methods to the parent view that the repeater exists in.
For
example (in code babble).
MyMainView.mxml
mx:script
public activeChild : MovieClip =
null;
function parentHandleMethod(evt)
{
// store current child view
to local var
activeChild =
evt.target'
// do server
call
}

MyChildView.mxml

Do you have a CFMX instance running on the JRun server.
I ran into an issue a week or so ago with a conflict between the
instructions for setting up verity and running a Flex server.
The basic problem was a classpath issue that was causing the JVM to use
the CFMX flash remoting instead of the generic flash remoting, so it was
looking in the wrong place for the class files when a remoting request
came through the Flex server.
Not sure if that's your issue, but I tracked it down by launching the
server instance in debug mode and lookging at the details for the error
when remoting couldn't find the classes.

RE: [flexcoders] Flex + Java Classes (as RemoteObjects) Config Question
Spike.
Thanks for the nudge in the right direction. I solved my issue (though I
haven't seen if this messes up CF yet) by updating the class path in the
jvm.config file to have it look in jrun/lib rather then Web-Inf/cfusion/lib
directory first. I seem to remember that this might not be the best thing
since CFusionMX had different versions of certain sub component (xml parsers
and the like) then Jrun. Can anyone from MM comment on that, esp if this
would mess up a CF7 install on a Java instance (our target prod
environment)?

You should be able to tell if that's the issue if you run the flex
server from the command line.
I can give you more details if you need them, but it's getting late here
