Re: [flexcoders] Re: what the hell am I doing wrong here
In the first CFC you set the return type to STRING but
actually returning a QUERY!
cffunction name=qpAdminFiles access=remote
returntype=string
output=true
cfargument name=mySearch type=string
required=yes /
cfquery name=qpAdminFiles
datasource=#application.dsn#
select * from tbl_smartPanel_propInfo
where fld_fileNum like '%#arguments.mySearch#%'
/cfquery
cfreturn qpAdminFiles /
/cffunction
In the second CFC you haven't specified a return type
but returning a QUERY again.
cffunction name=qpTest access=remote
output=true
cfargument name=mySearch type=string
required=no /
cfquery name=qpTest
datasource=#application.dsn#
select * from tbl_smartPanel_propInfo_Sale
where fld_fileNum like '%#arguments.mySearch#%'
/cfquery
cfreturn qpTest /
/cffunction
Note that coldfusion might get you the result when you
dont specify a return type(may be it assumes
returntype=any if you dont specify one) but for
webservice you should specify one.
Code a new CFC function which will return a STRING and
make sure you could get the output in your flex app.

Re: [flexcoders] How do I generate useful CFC Errors?
Most of my functions in the CFC return's an object (Struct) that has both the 'code' and 'message' apart from the other details you need. Here's an example cfcomponent .. cffunction name=getQuery hint= returntype=struct access=remote cfargument type=struct name=stData required=yes cfset var retStruct = StructNew() cfset retStruct['code']= 0 cfset retStruct['message'] = Message from Function getQuery: cftry cfquery name=qry_getqry datasource=#dsn# your query /cfquery cfset retStruct['dpCustomQuery'] = queryToArray(qry_getqry) cfset retStruct['code'] = 100 cfset retStruct['messaage'] = 'Custom query data retrieved successfully' cfcatch type=any cfset retStruct['message'] = Error Details : retStruct['message'] cfcatch.Message cfcatch.Detail /cfcatch /cftry cfreturn retStruct /cffunction /cfcomponent In your Flex code , you will always get 'code' and 'message' in your 'result' object and you can process your code based upon the 'code' you receive.

[flexcoders] DataGrid with colspans
Hi, I am trying to create a DataGrid with the following structure Colspaned Grid | Col B | Col A | Col B1 | Col B2 | Col B3 | Clicking on the bottom columns (Col A, Col B1 etc.) should sort the data as well. Its pretty simple to create such grid with mx:Grid tag, but I need all other functionality provided by a DataGrid. This I believe would need both Header CellRenderer and Column CellRenderer. I am trying to do this at my end but I am spending too much time to create one without success. Can you share your thoughts on how to create such grid? Thanks, Mohan __ Yahoo!

Subject: [flexcoders] Cell Renderers: How to put 2
images in datagrid cell
Hi All,
In my datagrid column I want to display 2 images in
a
datagrid cell and sometimes only one.
I have an image Renderer which works fine if I am
using only one image.
But when I have my second image 'image2' the first
image is not getting displayed at all. I beleive the
second image is overwriting the first one.
function createChildren(Void) : Void{
image = createClassObject( Image, image, 1,
{owner:this});
image2 = createClassObject( Image, image2,
1,
{owner:this});
}
I want to attach 'click' events to these buttons as
well.
Can someone explain me what I doing wrong here and
gimme tips to code this renderer? Would be great if
you can provide sample code for the same.
Thanks in advance
Mohan

[flexcoders] Cell Renderers: TreeGrid Renderer issue
Hi All,
I am using a Tree Grid sample provided by James at
http://www.cayambe.com/plog/index.php?op=ViewArticlearticleId=6blogId=1
It works fine as it is. But in my grid I had 2 more
columns and these columns have a simple ImageRenderer
attached to it.
mx:DataGrid id=mxmlTree dataProvider={dpGrid}
verticalAlign=middle width=700 height=500
variableRowHeight=true
rowHeight=50

cellRenderer=ImageRenderer/
mx:DataGridColumn columnName=stage2
headerText=Stage2 width=100
cellRenderer=ImageRenderer/
/mx:Array
/mx:columns
/mx:DataGrid
When I open the TreeRow in the grid, Child rows are
displayed and the images in Stage1 and Stage2 of the
child rows are displayed correctly.
But when I close the TreeRow the child rows get closed
but the images in the child rows still appear in the
grid.
Can someone explain what I need to do in Renderers to
make those images disappaer?
Thanks in advance

[flexcoders] Dispathching and Event from Combo Box cell renderer
Hi ,
I have a main.mxml where I have this DataGrid

mx:DataGridColumn headerText=Birthday
columnName=day /
mx:DataGridColumn headerText=Status
columnName=status editable=true
cellRenderer=ComboCellRenderer /
/mx:Array
/mx:columns
/mx:DataGrid
Whenever the combox box value is changed I want to
call a remote object with the datagrid's selectedItem
object.
I am handling the 'change' event in the
ComboCellRenderer and dispatching a 'statusChanged'
event and I also have a listener attached to main.mxml
for the 'statusChanged' event. But whenever the combo
box value is changed the listener function
onStatusChange in main.mxml is not called.
Can you tell me what I am missing here?

It's the ComboCellRenderer dispatching the

Subject: [flexcoders] Exchanging data between MXML
Components
Hi ,
I have two MXML components 'comp1' and 'comp2' in my
main application file 'main'
mx:application ...
comp1 id=cmp1 /
comp2 id=cmp2 /
/mx:application
'Comp1' populates a combo box 'cmb' with the result
from RemoteObject call.
Upon selecting an Item from combo box 'cmb', I
should
popualte a text box 'tbox' in 'Comp2'
Basically 'Comp2' is dependant on comp1.
Can someone explain me with a simple example on how
'Comp2' text box can receive the combo box data
everytime the combo box selection has changed?
Thanks,
Mohanraj

That should get you going. You might wanna make this
mapping a process,
which your service layer invokes before getting Vos
into and out of your
backend. You can make it so that you define
variables of your CF VO as
properties and loop over the properties to auto
populate the AS VO going out
and the same when you read the AS VO. You might also
wanna look into Tartan,
which has this mapping built into it and offers
seemless integration.
Let me know if you have any questions.

I believe the solution Dirk provided solves this
problem as well.
That is, in addition to Mehdi's initial solution #2:
remoteObject.cfFunction ( toPass, true );
You can use named argument syntax:
remoteObject.cfFunction({arg1:toPass});
Where arg1 is also the name of the argument in the
CFC method cfFunction.
Mohanraj, this is the solution I posted in my blog:
http://tomlink.net/blog/index.cfm?mode=entryentry=BBFE84D5-7E97-A3B0-EE0B2D

There's one more way of doing it without having

var testObject = new Array(); // it has to be

work if you did new Object()
testObject[var1] = var1;
testObject[var2] = var2
remoteObject.cfFunction ( testObject );

It works in Flash. Haven't tried it on Flex but
shouldn't have any

It is simple if all you want to pass is an
object with some
properties instead of sending over a class.

To disambiguate you use either of the two approaches

WOW! It works Mehdi. As you pointed out the second

magic! If possible, an explanation on why it works
with the second variable will be more useful Mehdi.
My guess is that one should have good knowledge of
Flash/ActionScript before venturing into doing any
complex stuff with FLEX.

1.

remoteObject.cfFunction ( toPass );
CF Side:

I'm sure it's not acceptable.

That works beautifully. The second arg from Flex
