[flexcoders] Re: first user tab is slow
We will run the profiler to see. We have a very large, form based app, so there may be something there. It can sometimes take up to 3 - 4 seconds to tab to the second form field. Some questions: 1. When is the sorted list computed? On the first tab? 2. Is there any way we can change when that happens? 3. What determines whether an object can receive focus? If we have a form/canvas over a form/canvas over ... is it only the visible form that has objects that can receive focus? 4. What do you mean by startup time delays? Loading the swf? --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: You can run the profiler to see why it is taking so long.

[flexcoders] Local computer access - best practices/successes
We have a need to access resources on the local computer. Specifically, devices connected to the serial/parallel/usb/... interfaces. I was wondering how others have succeeded with this in a flex/air environment. I was hoping that AIR would make this possible, but it doesn't appear so yet. Is this true? Would/could this be possible in the future? Other options? Locally installed app sending data over sockets? I think I remember seeing that flex/air could connect to such an app. Signed activex/applet browser plug-ins? Standard desktop app that sends data to server directly? Just wondering how others have approached this. Thanks

That is, be able to load an image (from server) on to a canvas, mark it up with the standard drawing tools, then save back to the server. Don't need to maintain the graphics layers. Ideally be able to pick from list of templates for drawing starting point. Anyone? Restriction: We are still on Flex 2 (backend = java)
[flexcoders] Flex 2 charting license with Flex 3 sdk
We purchased the Flex 2 charting license. Now, we have upgraded to the Flex 3 SDK. We haven't (yet) purchased Flex Builder 3 as we/I don't use Flex Builder very much. I do command line/ant builds and editing with my text editor du jour. However, since upgrading to the Flex 3 sdk, we are now getting the data visualization... watermark. Is there something I can do with my flex 2 license.properties to get this to work? In Flex 2, there was some command-line stuff with charting-source.jar that I needed to do. Or, do I need to purchase/upgrade to Flex Builder 3 (Pro)? If the latter is the case, I think I read that I can just put the license in the flex-config.xml file. Is this true? Thanks, Jim

Thanks, but I'm not looking to capture normal keyboard entries in

Any other thoughts anyone?

[flexcoders] Re: Custom combobox even propagation
I'll admit that I'm not sure you mean by the capture phase. I can
tell you what else I did.
In the customer comboxbox constructor, I did add this (pseudo code):
public MyComboBox () : void {
component = new ComboBox();
component.addEventListener(Keyboard.KEY_DOWN, handleIt);
}
private function handleIt(event:KeyboardEvent) : void {
Alert.show(Here);
}
And I did get the keyboard event when I pressed my function key.
However, it never seemed to bubble back up to where I really wanted to
handle it. I looked at the properties of the keyboard event and
bubbling was true.

[flexcoders] Re: Where is URLRequest data on server side
Thanks Seth. The problem is that I have a large (and growing) number of parameters (or rather, a large number of characters in the parameters) and I think I'm exceeding the limits of the HTTP query string/parameter map (I was thinking the limit was 256 or 1024 depending on get vs post). More specifically, I have a grid that I want to throw into a PDF. I use JasperReports on the backend. So, my first solution was to send the object IDs from the grid to the server, have the server do a bulk query, and then have JasperReports return the PDF. The problem now is that the list of IDs is growing and the actual number of characters is increasing. For example, the IDs used to be 1,2,3,..., now the are 10,11,12, . In the URL to my servlet, I do the following: myurl?ids=1,2,3 now myurl?ids=11,12,13 And so on. When I experience the issue, it's as if the request never even gets out the client, although I have yet to track that down (doing that now). I could change the parameters list to just send the search criteria (which generates the list/grid in the first place), but there is also some filtering involved, and I had hoped to not need to recreate the search/filter logic again on the server side.
