RE: [flexcoders] Security Sandbox Violation when loading image
Has anyone learned any more about this issue or come up with a solution? I am experiencing a very similar problem: images loaded from another domain are generating Security Sandbox Violations of the form: *** Security Sandbox Violation *** SecurityDomain 'http://host1/foo' tried to access incompatible context 'http://host2/bar/thumbnail?width=40height=52id=pap' It does not appear to be the mere loading of these images that causes this warning. It is applying effects and accessing properties. This is true even if I wrap the Image in another component like a Canvas that I then act on. Usually, the behavior of the app does not work when this error is produced but sporadically, in the same application instance with the same images, the behavior does work while still generating these errors. Very puzzling.

When I do, the debugger prints out a bunch of errors like this: *** Security Sandbox Violation *** SecurityDomain 'http://myserver.com/index.mxml?debug=true' tried to access incompatible context 'http://otherserver.com/someImage?wid=30' (Note, the image is dynamically generated and the URL should not include .jpg) Despite the errors, my images still seem to load in successfully, both through the Flex Builder IDE and when viewed directly in IE. Or so I thought. The weird thing I've discovered is that if my image paths are brought into my Flex app via an XML file, then I do get the errors above, but the images do load successfully.

I've double checked the exact path's that are being used in both situations by tracing out the path immediately before it is used as the value for the source property of the mx:Image tag and it is EXACTLY the same in both cases.

And finally, how do I prevent these violations from occurring in the first place? Thanks for any insight you can provide.

RE: [flexcoders] Security Sandbox Violation when loading image
Hi,
It should work without having
to convert into to the AS2 type class as you did. If you simply
do:
results[0].price
results[1].price
this should get you the price
of the first product and seconds products. I assumed "results" is the name of
the object that contains the results of the RO call.

Security Sandbox Violation when loading image
Well, I figured out why I was experiencing different
behavior when pulling data in from an XML file vs. pulling it in via a remote
object. My remote object method call was returning an Array of objects which on
the Java side were instances of a simple data object class I had created called
com.myclient.Product. These objects had three properties:
label(String), imageId(String), and price(Double) which were accessible through
appropriately named getter methods. When stepping through the debugger in Flex
Builder, I could see these objects were coming through just fine with the
appropriate property names and values, but when I tried to pass each object to
my custom display component it was not displaying them, even when the same
display component had no problem displaying similar data Objects if they were
created in the AS code. So I went ahead and created an .as class called
com.myclient.myapp.Product and associated it with the Java
class using the following static variable invocation:
static var regClass =
Object.registerClass("com.myclient.Product",
com.myclient.myapp.Product);
After doing that, everything worked just
fine.
So my questions are, why did I have to create that
ActionScript class to get things to work? Is there a way to pass back a generic
AS Object from a remote object call? Would passing back objects of type
java.util.Map be the answer? Which is the better practice, passing back a
java.util.Map to be converted to an untyped Object or creating .as classes for
each typed Object that can be retured from a remote object
call.

RE: [flexcoders] Security Sandbox Violation when loading image
You shouldnt have had to create an AS class, Im not sure why it wouldnt have worked. The regular object should have had the data you needed. Best practice is to create the class though.

RE: [flexcoders] Security Sandbox Violation when loading image
Im not an expert at this by any stretch. The security sandbox violation when dealing with images/movies generally occurs because the SWF that did the loading (myserver.com/index.mxml) tries to access properties of the loaded movie (otherserver.com/someImage, and yes I realize it may not be a SWF). Im not sure why properties youd be trying to access though, maybe depth swapping or something? Maybe the Flex app does it on its own. I wonder if Manish ran into this with the map example J As for it working with XML and not with RemoteObject, that does strike me as strange. The only thing I can think of would be that somehow establishing a connection to your source server prevents the SWF from thinking that it should be allowed to contact the other server. Do you own the other server? Any chance you could try putting a crossdomain.xml file on there (see technotes for info on crossdomain).
