Re: [flexcoders] Re: Flex Builder on Linux been scrapped ?
Well most or all decisions are based on emotion, despite what we rationalists think, but I take your point. I'd like to write something here thats actually useful and might contribute a tiny item to the knowledge pile at Adobe, without boring everybody with personal details- 1) windows + Adobe puts me over budget at home, and I am accustomed to using all-open software, and one of the appeals of Flex Builder on Linux was I could learn it without forking over money. and yes it galls me to send money to MS. 2) My company is a Linux shop and no license money is available for experimental projects; CTO wants Java and the only way I can convince him Flex/Flash is better is to show something else that works. 3) I need to see what its like developing without the Flex Builder framework. I am already the only one in the building who uses an IDE or visual debugger. Just as I had no idea how Sun was going to make money on Java ( opposed to IBM who does) I don't know how Adobe can make money giving away tools, but it sure looks like open tools are going to win the battle in the long run, and proprietary tools will lose market share. Maybe Adobe can sell the visual designer stuff? Open source software people are so wary of proprietary tools because we have seen over and over how tool sets get munged over time, or even abandoned, how open tools have vastly better tech support, and now finally with Eclipse, open tools are achieving parity with the visual IDE stuff from vendors. It seemed to me that Adobe was following a semi-open model with Flex, for instance open bug reporting, and that attracted me in the first place. and so forth John daxdr9 wrote: If your willing to drop Flex because they don't sell an IDE for Linux, you're basing a technical decision on emotion.

Re: [flexcoders] Flex Builder on Linux been scrapped ?
If Adobe drops Linux support for Flex, then I will probably drop Flex. I won't maintain a Windows or Mac box at home, and my company really doesn't want to invest in any more Windows apps. I don't want to invest myself in technology I can't run independently of whoever I happen to be working for today. Seeing the fickleness of the corporate owners of development tools is what sent us to Linux and open source tools in the first place. We can't bet our products on some whim of Adobe.

Re: [flexcoders] Flex Builder on Linux been scrapped ?
Guy I could use the bare SDK of course. I hadn't really tried it before because the Flex Builder Eclipse plugin seemed like a good idea. And there is *some* support for it in the community, I don't know how much. You're right I should try that before I give up. blame Adobe is not quite right, trust is more like it. Watching Java slowly worm its way out of Sun's grasp to the point where its now more or less open-source should provide a positive prediction for the eventual outcome, but Adobe ain't Sun, but then Sun ain't either now. Does Adobe have the right corporate culture to nurture an open-source project? I like the way they are running Flex otherwise, but maybe I indulged in wishful thinking on the Linux support. John Guy Morton wrote: Wouldn't you still be able to build your own IDE using the free SDK? As I understand it a lot of people do this now to avoid having to buy FB, and I imagine Linux users would be relatively common within that group. If sales for a linux version of FB are too low to justify the ongoing cost of development, you can hardly blame Adobe for that. Their support for *nix is better than most. Guy

[flexcoders] Cant empty context menu- previous answers don't work...
-This was discussed as recent;y as late last month, but I have tried all the solutions and they are not working.- -problem: I want to get control of the contextMenu, and I need to remove the built-in items. I am able to add menuitems -I tried advice from these sources: http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetailsproductId=2postId=2201 flexcoders 12/29/2008 -they said: if you run hidebuiltins() on the systemmanager you can wipe the menu clean. When I look in the debugger I see that a list of print, zoom and so forth are indeed made false, but when I run the app, I get the standard Flash context menu with show redraw debugger settings about adobe flash and I can't find these labels in the debugger, though they must be there *somewhere*. I *do* see my new menu with only a single item. Its as if the flash palyer itself adds the menu workaround: I'd be just as happy to get a right-click event on my sprite, and dump the context menu altogether! building in: Flex3.0 flexbuilder for Linux running on: Firefox 3.x on Linux, Flash debugger v 9 0 11 5 0 thanks John
Re: [flexcoders] Cant empty context menu- previous answers don't work...
well since nobody had time to answer yet, I kept digging. here's one bug: if you add Settings as part of the string which forms your custom menuitem label, not just the whole String which could collide with the Settings menu, but part of a custom string, it won't show at all in the menu, and no error is thrown. Parameters is acceptable, but thats all I know one way or the other. see Alex's previous comment: http://tech.groups.yahoo.com/group/flexcoders/message/125171 this code definitely does NOT clear the two standard menuitems, Settings... and About... nor the debugger-player's debugger and show redraw regions var menuItem:ContextMenuItem = new ContextMenuItem(Our switch: Change Parameters); menuItem.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,createParamPopUp); var customContextMenu:ContextMenu = new ContextMenu(); customContextMenu.hideBuiltInItems(); customContextMenu.customItems.push(menuItem); Though it does add an item, and run the associated function. Has anyone cleared the *whole* contextMenu out? or Taken control of mouse-rt-click events so as to avoid the standard contextMenu? John

I am feeding data to a chart from an arraycollection. When I test it by

I assemble the data piece by piece, the chart fails. A correction of my
syntax would be great, and explanation even better!
I have tried creating an object, then using addItem to add it to
simpleData, and I have tried using addItem directly in simpleData, and
here I try it using a string- the result is, as you can see from the

Re: [flexcoders] multiple data sources not loading except in MXMLapp
great. good news = I am doing something wrong
never mind Flare - the data is never getting there...
here's what I have:
an xml source and a graphml source. Each will drive a visualization.
Maybe more sources to come...
here's what I want to do:
make a class or component for each type of visualization, and pull the
data in inside the class.
so far:
when I make a component and try to use HTTPService or URLloader I get no
data.
when I tried two httpservice tags in the MXMLapp, I get data from only
one, I assume because the event never fires in one... But I'd rather
call HTTPService from inside the component anyway.

And the ArrayCollection is buried deep in the the object and I also build the series items for the chart on the fly in Actionscript. So I don't have access to the series items in the chart I create (for instance to reassign the dataproviders), nor do I have easy access to the ArrayCollections themselves since they are buried in the ActionScript objects. Here's some pseudocode of how the charts get created which illustrates the problem. in ReportObject for each ChartObject in ReportObject create CartesianChart for each AxisObject in ChartObject create DateTimeAxis and assign it to chart for each SeriesObject in AxisObject create Series and assign it to axis bind SeriesObject.data to Series.dataprovider So when I get the next ReportObject pushed to the flex app from the server, the structure of the Report is exactly the same (i.e. x# axes, x# series for a given axis, etc) but the data has been updated and the series do not pick this up.
Re: [flexcoders] updating data in Actionscript
I am using an httpservice to xml files on other servers. The display changes when the file changes, mostly. All you have to do is bind the dataprovider. Maybe your problem is different? Theres lots of documentation for what I am doing John I have been trying to find an answer for this with no success. How do you get flex to refresh data bindings using objects which are passed via remoting?

Thanks Josh, xray seems to be not at Flex3 yet, and the last news was 2007. Though it seems to be just what I need. The debugger in Linux Flex Builder Eclipse debugger works fine AFAIK.

[flexcoders] Debugging: general advice
I read a thread from a few weeks ago, and Amy was using Alert to debug in the browser. So am I, and its moderately successful, but I wonder if there is a better way? I: linux, eclipse, flex builder For instance I'd like to step through on classes that aren't invoked until the user clicks. Is there any way to do this other than re-writing the code to call the bad section automatically? yes the damn debugging flash crashes FireFox all the time. sigh. fortunately I can type kill and Firefox remembers where I was tips and dope-slaps welcome.

The gives me a Security error accessing url Alert. I've read in the past that Flash is strict about the interpretations of domains, so I'm not surprised by this behavior. Further, I am theorizing this is happening because the WSDL file for the service uses the numeric address rather than localhost. Since that is the only usage of the numeric IP address I can find (all the URLs I have constructed use localhost). I have a crossdomain.xml file that is reachable at http://127.0.0.1:8080:8080/crossdomain.xml;. It's not solving the problem. The crossdomain file has this format: cross-domain-policy allow-access-from domain=* to-ports=* secure=false/ /cross-domain-policy The web service is built using Apache Axis2. So, its address in the WSDL is: http://l27.0.0.1:8080/axis2/services/TestService. Is there some special location or content to the policy file that I'm missing? Thank you.
Re: [flexcoders] Re: Security and dual localhost address question
aha! the hosts file ( see Fotis for location I believe he has it right for WinXP) lists ip addresses with domain names so your PC knows that me.mydomain.com equates to 200.111.86.76 The key here is that the OS reads the hosts file first and then asks DNS, so whatever you put in will override what your public DNS server says. see name resolution and domain name service IIRC Windows help is pretty good on this... When Tomcat ( or any app ) Gets an http request it has to be able to figure out the IP address from either localhost or name.domain.com hence the need for hosts file and DNS. If your browser says http://...; it still uses the network interface, even if its all on one machine. this is a Good Thing. If it uses file://... then not. This is why the raw ip address works and localhost doesn't - see? HTH sorry if its a bit pedantic John ralcab wrote: (3) Excuse my ignorance, but what's a host file?

Re: [flexcoders] Re: Security and dual localhost address question
Fotis, you may be right, but messing with the hosts file and the crossdomain file did fix the problem for me, albeit on a Linux box. It probably also matters what the setup for his Tomcat is too. It puzzled me too, because I am accustomed to having localhost resolve correctly, though its in the hosts file by default on *nix OSes.. dunno what Windows does. If the problem is resolving localhost the solution is in the places we pointed him John Fotis Chatzinikos wrote: John, appart from your correct info on dns, I do not think thats John's problem, (confict on Johns' here :-)...

Re: [flexcoders] Do you use a Mac?
Just in case anybody cares, it is also possible to use Flex Builder on Linux. Since I don't normally use any non-free software, and I do a lot of Linux sys admin, thats good for me. There are a few apps I can't duplicate, like Illustrator and Google Sketchup and Rhino, but mostly I don't miss anything from Windows-land. true I don't care about iTunesmusic, but I do subscribe to podcasts. (I don't do professional graphics or audio.) In the last year or so the package system for Ubuntu has gotten mature, so that software installation is just select and click. It used to be a PITA sometimes. Most of the sys admin apps now work in KDE, too. Theres a few things that still don't work, but in Linux you can be pretty sure they'll be fixed. I like OSX, too, and used DOS and Windows since 1985. just sayin'

[flexcoders] getStyle(fill) from chart series fails
I must be doing something simple wrong here.
What I am doing:
creating a column chart entirely in AS, and controlling the colors, and
series, and legend in AS. The legend will be in a grid, instead of
automatic in the chart.
once the XML data is acquired, the makeserviceschart assembles the
chart, including choosing which data to include, and which colors to
use, and then finally calls drawlegend, passing the grid and chart
objects, in order to assemble the legend in a Grid.
What doesn't work:
The legend gets the data name ( label) correct, but doesn't get the fill
color.
Back inside the makeserviceschart, I can't trace out the fill color
using getStyle either, even though I have just set it using setStyle.
The getStyle syntax is a cutpaste from the Adobe example code app:
http://blogs.adobe.com/flexdoc/2008/07/customized_legend_layout.html
which DOES work on my system
// SMALL SNIPPET

Re: [flexcoders] How to keep Tree control synchronized with the database. Please Help
I am working on a similar problem... I don't use PostGres, but there may be some sort of export to XML function. *If* that can fire on changes ( or you set up the inserts/updates that way), then you have something that an httpservice can acquire directly. But somebody still has to ask the file if it changed... unless You use a socket connection to stuff an event into the dataprovider. Theres some examples in the adobe docs. or you poll, but don't refresh the whole html page, just the data in the swf, and only when it changes. My users cant tell the difference between polling and the socket connection in the two demos I made. I'm just a newbie, so if there is another way, I'd sure like to hear about it.

AHA he said.
Generally speaking the variable equivalent of

would be
var o:Object = new Object();
o.x = 1234;
obviously I warn't raised on OO style I was still looking for *
your code is trying to have the variable name as a vaiable itself, so the
equivalent would be:
o[x] = 1234;
var variableName:String = x;
var variableValue:Number = 1234;
o[variableName] = variableValue.
excellent. Thanks very much
I'm rather suspicious of your XML handling code, but I won't go there!
Oh that was almost pseudo-code, to make it easier to read, without

there will be extensive re-factoring once it all works and my

[flexcoders] Syntax of using a variable to make an object
I am stuck on some basic AS syntax.
Here is some Adobe sample code:
[Bindable]
public var dpac:ArrayCollection = new ArrayCollection([
{A:2000},{A:3000}, {A:6000} ]);
public function addDataItem():void {
var o:Object = {A:2000};
dpac.addItem(o);
}
Inside a loop, I need to add a data item to an arraycollection, but I
need to get the name of the data and the result of the data from an XML
file.
OK I've got those two things working, but now my name and dataresult are
variables not ints and strings.
[Bindable]
public var dpac:ArrayCollection = new ArrayCollection;
for each ( var something:XML in myXML.children()) {
var dataresult:Obj = something ; // don't know type of result
ahead of time...
var name:String = something.name ;
var o:Object = { name + ':' + dataresult } // WRONG!
dpac.addItem(o);
}
I am going wrong where I try to create an object out of method-results or
variables that can be additem'ed to an arraycollection.
And I don't really get the curly brace syntax, as you can see...
Thanks for guidance here...

Re: [flexcoders] Re: Feeding complex XMLdata to charts: Flex3
well it may be easier... but I liked the obvious page layout of the mx tags, separated from the AS code. No doubt I can still have what I want. My comment on the documentation is that as long as you are using very simple data, everything goes together smoothly, but as soon as I introduced real data from this big ugly XML file, I found myself off in the weeds. and thanks again, I am still working up to taking your code apart.

Re: [flexcoders] Feeding complex XMLdata to charts: Flex3
For total spanking newbies reading this: See Amy's code and also this simplified version http://livedocs.adobe.com/flex/3/html/help.html?content=charts_intro_7.html stuff I didn't get that tripped me up- 1) You don't have to use the mx:ColumnChart at all - you can do everything in AS instead. This is very confusing, because the call in AS that actually creates the chart is addChild as in // Attach chart and legend to the display list. p1.addChild(myChart); p1.addChild(legend1); My initial reaction is yuck but knowing nothing, its worth will likely be revealed to me later. 2) use of the child method on XML objects, I need to practice this and figure it out. 3) I was right, the bar charts just want an array of arrays for data, but I lacked the tools to create that from the XML. further comment welcome.

[flexcoders] Feeding complex XMLdata to charts: Flex3
Good morning in PDT, and thanks for being here.
Me: new to AS Flex, building a Linux-based dashboard, using
Flexbuilder alpha for Linux in Eclipse
( this does not have all features compared to Windows and OSX I believe,
and may be buggy)
*Problem:* I've been given an XML schema for incoming data thats
complex, and well, may not be optimum. :)
When I follow the tutorials using simple data,
data
item
etheth0/eth
packets1234/packets
bps3005/bps
/item
item
etheth1/eth
packets517/packets
bps4335/bps
/item
...
/data
I am able to get a dynamic bar chart that responds to changes in number
of members of the data array of elements. But my real data is complex
( see below) and it appears to me that the dataFunc to chart series
dataprovider connection, which understands simple arrays, gets confused
with complex arrays.
*What I get thats wrong:*
Trace shows me getting results like
peas data1 /peas
peas data2 /peas
or using a different notation,
data1data2
when I expect an array of data1,data2
and the chart won't work at all.
*What I want to know:* I want some guidance to help me avoid dead ends-
Is my XML just flat not suitable?
Am I wrong about the problem?
Do I need to do some complicated restructuring of the data before I
return it from the dataFunc, so I send a simple array like shown above?
Thanks!
John
