RE: [flexcoders] Error #1009: Property or Mehtod of a null object reference
Works in dev environment but not in production s often is a data
service security issue. Any chance that is the case here?
If not, consider adding trace statements in your code around the
offending area. Run the debug swf from the production server from your
dev maching where you have a debug player. You will be able to see the
trace statements. I use lines like this:
trace(myObject is null? + (myObject == null));

Subject: [flexcoders] Error #1009: Property or Mehtod of a null object
reference
Hello All,
Firstly I understand what causes the #1009 error.
What I am having trouble with is reproducing it in my flex development
environment.
I have an application that calls custom components into a ViewStack.
When the user changes sections within the viewstack it fires an event
which calls a public method called saveSection within the custom
component - the section they just left.
When debugged and run within my Flex dev environment it works fine,
until I deploy it to another development machine. It's then that I get
the Error 1009.
This is driving me crazy. This code has previously worked fine.
I'm happy to post some pseudo code or examples if needed, but generally
I'm after advice. If I am viewing the component called into the
viewstack... how can it be null? Complicating this is that the same code
called for the other sections works as expected!
The creationPolicy on the viewstack is all
MainApp
{changeSectionHandler - oldSection.saveSection()}
ViewStack
SectionA
{saveSection()}
SectionB
{saveSection()}
SectionC
{saveSection()}
Any help appreciated.
Cheers
Steve

Use a debug build so you get line numbers and post the entire stacktrace if it
isn't clear where the problem is.

RE: [flexcoders] error 1009 Solved tabnavigator issue hiding items not shown to user
Setting creationPolicy=all is not recommended. Your application will take much more time to initialize.

RE: [flexcoders] ERROR 1009
You're right. The stylesheet is being loaded before the TextArea is created, so it's attempting to apply the style to something that doesn't exist. Yeah, it's annoying, but there are ways around it.

Re: [flexcoders] Error 1009 when running on different server
the problem isnt in your server machine.
When you call from remoteObject to collect data from your cfc you´re
trying to fill out the form detail without the response back complete from
the collection you invoked.
Suggestion is. try to fill the detail page with a way to when the result of
method complete, you fill out the master detail page.
ex:::
remoteobject
method namebla result=myresult(event)/
/remoteobject
script
public function myresult(event:resultevent):void
{
// code to fill the master detail here
}

1009 when it tries to return the object with the details:
TypeError: Error #1009: Cannot access a property or method of a null

Both servers appear to be identical (Windows 2003, CF version 7.02

I've checked the cfc and they work as expected on both machines.
Any idea why the application would work on one server but not on the
other?

Re: [flexcoders] Error #1009: null has no properties.
Hi, If you are using mx:AdChild on the Accordion, try setting the property of the AddChild tag's creationPolicy to 'all'. This way all the children are created and you shouldn't get this error, I had same issues with the TabNavigator. Any other options, well I don't know about yet ;-) The null has no properties just means that the instance that Flex expected to go to is not created yet.
