Re: [flexcoders] Re: No debugging information available for invocation of methods on server-side
Hi Andrew,
{Tomcat_home}/logs/stdout.log is the only file that gets anything and
it is minimal. I don't seem to have a catalina.out, but perhaps this
is stdout.log under Tomcat 5.0?
Thanks for the reminder about the net debugger. I picks up my calls
but the information is limited. For example, when my java method threw
a NullPointerException the NetDebugger gave me the following fairly
cryptic message...
DebugId: 0

Have you got an example of debug output from remote calls from your
logs? I'm interested what it looks like.

Hey Dan,
have you tried looking at catalina.out?
Also if you have turned on all of the debugging on the flex-config how
about running the NetConnectionDebugger ? It will help monitor all
remoteObject calls and the result/fault returns from your java backend.
You can find it in your flex install directory
/extras/netConnectionDebugger/

Do you have a

If you don't register the Java/AS class mapping it defaults to ASObject.

Hi cazzaran,
how did you solve your problem? I'm interested in a solution, because I
have a very similar problem. In my case I have an object (OgoJobVO) in
which is another object (OgoAccountVO) in which is another object
(OgoPersonVO).
When I get the Job-Object from the Server, everything works fine. When
I
try to call a function in a POJO where a Job-Object as an argument, I
get the following error in the NetConnectionDebugger:
Status (object #2)
.code: "Server.Processing"
.description: "Cannot invoke method 'insertJob'."
.details: "The expected argument types are (ogo.OgoJobVO,
java.lang.String, java.lang.String) but the supplied types were

converted to (null, null, null)."

.type: ""
.rootcause (object #3)
..code: (undefined)
..description: "Type ogo.vo.OgoJobVO not found"
..details: ""
..level: "error"
..type: ""
The call looks like this:
var call = service.insertJob(jobarg,login,password);
I tested the argument jobarg with
if(jobarg instanceof OgoJobVO){
text="type of OgoJobVO";
}
else{
text="is not type of OgoJobVO";
}
mx.core.Application.application.debugtext = text;
This returns "type of OgoJobVO".
I really would like to use nested Objects.
I appreciate for any suggestions.

Below's the serialized request. You can see that the organization

Re: [flexcoders] Use mx:Model as well as Cairngorm ViewHelper pattern? -- Best-practice for using validators?
I've removed my models and just have the ViewHelper. My field validators are just bound directly to the controls rather than to the mx:Model.

Re: [flexcoders] flex and jsp
I think you want thissearch the Flex documentation for
"flashvars". AFAIK this is the only way to pass data into your Flex
app.
Dan
Using flashVars
You can pass variables to your Flex applications using the flashVars
property in the object and embed
tags in your HTML wrapper. You do this either when you write your own
custom HTML wrapper or when you use the Flex JSP Tag Library's flash
and mxml tags to generate the HTML output that
displays the Flex application.
The following example sets the values of the firstname,
middlename, and lastname flashVars
properties:
object classid='' codebase='' width='500' height='500'
param name='flashVars' value='firstname=Reinermiddlename=Tlastname=Knizia'
param name='src' value='vartest.mxml.swf'
embed pluginspage='http://www.macromedia.com/go/getflashplayer' width='500' height='500' flashVars='' src='' /
/object
To pass flashVars to a Flex application in a JSP, add
the flashvar tag that defines the flashVars
properties to the flash or mxml
tag, as the following example shows:
%@ taglib uri="FlexTagLib" prefix="mm" %
h2FlashVars Parameters/h2
mm:flash source="jsptest2.swf" supportembed="false" border="5"
mm:flashvar name="firstname" value="Reiner" /
mm:flashvar name="middlename" value="T" /
mm:flashvar name="lastname" value="Knizia" /
/mm:flash

Hi all,
I'm trying to pass a param to my mxml file via jsp.
Here is my code:
mm:mxml source="/myDir/myFile.mxml"
mm:param name="REMOTE_ADDR" value="%= request.getRemoteAddr()
%" /
/mm:mxml
If I echo the jsp code at the top of the page it workes fine, it just
doesnt get passed to my mxml file. I have REMOTE_ADDR declared in a
script block at the beginning of my mxml file.
I have also tried the sample from the this article
http://www.macromedia.com/devnet/flex/articles/server_perf_05.html
as
follows (this also doesnt work):
% session.setAttribute("username", "brandon"); %
%@ taglib uri="FlexTagLib" prefix="mm" %
mm:mxml
mm:param name="userName" value="%=
session.getAttribute("username")
%" /
mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
width="200" height="200"
mx:Script
var userName:String;
/mx:Script
mx:Label id="uName" text="Hi {userName}"/
/mx:Application
/mm:mxml
Any ideas on how I can get these to work?
Andrew.

Re: [flexcoders] HTTPService.send
Not sure about the first two, but for 3. the call to the HTTPService generates a pending call which is not executed until you leave the current scope (allowing you to bind to the result event). So I don't think there are any race conditions. cheers Dan viraf_bankwalla wrote: The HTTPService.send has the following signature send( parameters: Object) : Object 1.

Could someone please explain this object and what operations may be performed on it. 3. If the returned object is a handle to the request, can I set the decodeXML, encodeXML, fault, result properties on it?

Re: [flexcoders] How to get access to HttpSession in a stateful-c lass
Steven, Thanks for the reply. I realise my question wasn't quite clear - I wanted to access objects in the request object on the client. Or more specifically, pass a complex object that is available to the JSP into the Flex app. This page was what I was after... http://livedocs.macromedia.com/flex/15/flex_docs_en/wwhelp/wwhimpl/common/html/wwhelp.htm?href=2253.htm But it seems that I am limited to passing simple strings. So to use complex data for the flex app to initialize I need to call a remote service (RemoteObject, HTTP, Webservice), yes? Dan Steven Webster wrote: Dan, This may be a stupid question, but if your flex app is wrapped in in a jsp file (using something like mm:mxml source=.../) can you access variables in request scope?

This may be a stupid question, but if your flex app is wrapped in in a jsp file (using something like mm:mxml source=.../) can you access variables in request scope?

I also have a GroupDelegate, that obviously handles Group stuff. I need to be able to access the User variable in the UserDelegate so I can figure out some information about the user before I perform the Group operations (i.e. authorization, etc). My problem is that my Delegates are just POJOs, and so have no knowledge of requests, or sessions. Is there a way to get to the session that the stateful-class is being held in, or get at the request that is associated with that session? I know I could pass User information over the wire to my GroupDelegate, but this is inefficient, since the data's right there in memory on the server. Any help is appreciated! *Yahoo!
