We need/want to upgrade to Flex 3 on the UI side, but would prefer to leave our remote services unchanged (not even touch the server side of the code/libraries) until we understand our licensing options.

My suggestion would be to a) (easiest) just create a separate upload page b) (little more complicated) create an upload page that doesn't save to server but rather just converts the file to base64 encoded string, the flex app listens for the uploadCompleteData - that data will be your file in base64 encoded string. You can send that in a web service. For b - you can look at the Excel library (http://code.google.com/p/as3xls/) - more specifically - look at the php script which does this to load a local Excel file into the flex app. It does upload the file to the server, but doesn't save it, just spits it back in a form usable by Flex.

Hi,
It's ICommand.
The reason is you can stack interfaces on top of each other allowing more
decoupling to the implementing concrete classes.
This interface is obvious. Any class that implements it needs eval() and
only eval. It's like a singleton declaration of implementation.
If you jammed this evel() method into IUIComponent, maybe all components
don't need eval. Make sense?
Also another good example of this type of interface in the flex framework
is IDataRenderer, it's only declared property is 'data'.

[flexcoders] AdvancedDataGridHeaderRenderer loses focus on set dataProvider
Take a look at this video (sorry the mouse cursor does not appear in it): http://screencast.com/t/VECik0vjuk Every time the dataProvider is set the textfield loses focus, and I can't find a way to restore it. So essentially on each key stroke the textfield loses focus, which renders it useless inside the advanceddatagridheaderrenderer. I'll provide source if necessary, just looking for a quick fix if there is one. Sincerely, Ryan Gravener http://twitter.com/ryangravener

So if the TextInput is empty, then the required validation kicks in, and if the text property contains for example, foo, then then the Validator fires as well. Is there a quick and easy way to do this without overridding the Validator?

Tim thanks for your response. I have a very simple datagrid

from untyped to typed alters the behavior of the datagrid with respect
to the look of the selected row. Doesn't matter if I use the objects
returned from the server or just manufacture a collection of typed
objects.
So far I'm using the work-around of manufacturing untyped objects.

datagrid the behavior of the datagrid changed.
1. if the dataProvider is an ArrayCollection of untyped objects,
i.e.,
{name:blah,phone:1231231234}, it performs as expected, i.e.,
when
you click on a row it gains the selected row highlight
2. if the dataProvider is an ArrayCollection of typed objects, i.e.,
User objects with name and phone attributes, it performs
differently.
While the datagrid knows that a row is selected, the selected row
looks as if it is unselected.
Now it is slightly more complicated in that the User object extends
another base class and both use the Bindable metadata tag and are
RemoteClassed to Java objects on the server, and have another 30
attributes.. but I'm still stymied. Anyone have a suggestion for a
work-around besides creating untyped objects for every object at
runtime? What would the code look like to force a selected style to
show up for the selected row?

It would be impossible to create an item in the array to show, it would need to part of the combobox control. So on initial load of the application, the combobox would display something like 'Click to Select...'. Any thoughts? Thanks, -- Ryan Gravener http://twitter.com/ryangravener

When a hosting company claims they support CF8, does it usually include the embed LCDS? Is dedicated server the only way to go? Is RMTP channel practical for flex on Internet? or just for Intranet?

Re: [flexcoders] Re: What files should be in the WEB-INF/flex directory to dynamically compile
Why not just compile the flex app when you compile your webapp? On Wed, Jul 16, 2008 at 11:50 AM, Andrew Longley [EMAIL PROTECTED] wrote: Thanks Tom. The phrase web-tier compiler was what I needed. I found the Flex compiler module for J2EE application servers after much searching at the page http://opensource.adobe.com/wiki/display/flexsdk/Downloads. What a brutal search for something so simple! The result of this is webtier.war, which can be deployed to any web app server. I can then add my Flex app and it dynamically recompiles, and it's the Flex 3 version. Thanks again.

There's a 'web tier compiler' in the Flex 3 SDK, and plenty of docs on the web. Don't try and figure this out blind. Bottom line, I'm looking for a Flex 3 project that compiles dynamically when deployed under a web app server, or information towards that end. Thanks for any help. Why ? Almost always off-line compilation is what is best. -- Tom Chiverton -- Ryan Gravener http://twitter.com/ryangravener
