[flexcoders] Change alpha of image clicked in a repeater
I have a component that displays thumbnails using an image tag
inside of a repeater. What I would like to do is change the alpha of
the thumbnail when it is clicked to show the full image. A list of
image names is being used as the dataprovider for the repeater in
the component. I can get the name of the image selected but am at a
loss as to how to change the alpha.
Component to view thumbnails
mx:HBox
mx:Repeater id=thisRepeater dataProvider={imageList}
mx:Image verticalAlign=bottom click=displayImage
(event.currentTarget.getRepeaterItem()) rollOut=destroyBigTip()
rollOver=createBigTip(event.currentTarget.getRepeaterItem())
id=currentImage source={currentImageURL + genusName + '/' +
speciesName + '/tn_' + thisRepeater.currentItem.ImageName}
/mx:Image
/mx:Repeater
/mx:HBox
In the application file
mx:Canvas id=viewCanvas styleName=thumbCanvas
width=600 height=130 x=231.5 y=11
Components:thumbViewerHorizontal id = thView

[flexcoders] Re: Simple RemoteObject call - cannot figure out what is wrong
1. May seem simple but run the cfc from a cfm page in the same
location at the flex file. I always make sure my cfc works outside
of flex
2. Installl this to help with debuging

This may provide some additional information

Hi all,
I am trying to switch from httpservice into remoteobject but i m
having a
problem in here which i cannot figure out how to solve.
I have managed to read data using a CFC and display them in a grid
(I have
really wrote my own component that I can pass SQL there and
display data).
However I cannot pass parameters into the CFC and insert or update
my
database. Here is my code:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;

mx:Script

private function submitForm():void

}
]]
/mx:Script
mx:RemoteObject id=myService destination=ColdFusion source=
GeorgeForm.cfcs.querylib/
mx:method name=qExecQuery /
/mx:RemoteObject
mx:Button x=27 y=36 label=Button click=submitForm();/
/mx:Application
and here is a VERY simple CFC
cfcomponent output=false
cffunction name=qExecQuery access=remote
cfquery name=qsQuery datasource=cfartgallery
insert into tbl_test (firstName)
values ('FlexGeorge')
/cfquery
cfreturn /
/cffunction
/cfcomponent
When I click the button, I getr the following error:
[RPC Fault faultString=Unable to invoke CFC
faultCode=Server.Processing
faultDetail=For details, turn on Robust Exception Information in

any ideas on how to achieve this simple task that I m trying to do?

[flexcoders] Find parent of selected item in tree
I just can not seem to figure out how to get the parent of a selected item ([EMAIL PROTECTED]). In this case I need to know the genus name when a species is selected. Note that a species name is not unique to a genus name, Uromyces ingae and Puccinia ingae public var nameData:XML = allData genus name=Uromyces species name=ingae/ species name=elegans/ species name=dolicholi/ /genus genus name=Ravenelia species name=irregularis / /genus genus name=Puccinia species name=ingae/ species name=manoelae/ species name=longirostris/ /genus /allData Thanks, Dave

[flexcoders] combo box - missing value
I have a simple combo box currently showing 10 values. When I make the rowCount larger than the number of values all is ok. However if I set the rowCount to 8 (scroll bar appears) some of the values are displayed as blank lines. As you scroll up and the down the value that appears as blank changes. Need help. Thanks, Dave
[flexcoders] Re: Which chart was clicked
Ely:
Thanks alot. Worked fine and I learned something about closures.

You've got three options:
1) shove the id off into a member field, and grab it when the RO
returns. This is the least well designed response, since it can
break
in use cases where you've got multiple requests out and you don't
just
want last-out-wins. Might be OK for your use case though.
2) send the id up to the RO, and have it include it in the
response. A
little wasteful, since the RO doesn't care about the id, but in
general
this 'cookie' pattern is a way to maintain state across RO calls.
3) use closures. you could do something like this:
private function chartClickHandler(e:MouseEvent):void
{
var id:String = UIComponent(e.currentTarget).id;
var roCB:Function = function(e:ResultEvent):void
{
nameList = event.result as ArrayCollection;
currentState = showNames;
gridPanel.title = id;
myRemoteObject.getNomeForNames.removeEventListener
(result,roCB);
}
myRemoteObject.getNomeForNames.addEventListener(result,roCB);
myRemoteObject.getNomeForNames(id);
}
PieChart id=... click=chartClickHandler(event); ... /

Subject: [flexcoders] Which chart was clicked
I have 3 pie charts which when clicked run the same remoteObject
method. Is there a way within the method that I can determine
which
pie chart was clicked. I want to pass the id of the clicked chart
as
a variable in the result function of the remoteObject method.
Thanks, Dave
