[flexcoders] Re: Exceeding Flash's Capabilities?
I've never tried to display more than 20 or so series, but I do have an app
that has 5692 records with 4 series each for a total of 17076 data points. It
is displayed in a bar chart. Well it isn't actually displayed since that's
about 17 bars per pixel, but the bars are actually there and you get data tips
when you mouse over where the bars should be. I hide the chart from users when
there is too much data, and show them the data in a data grid . But when the
data is filtered down to around 3 or 4 bars per pixel the chart updates and the
bars display.
So while there is too much data to actually plot due to the limitations of the
screen there is no problem working with it in Flex and I am able to display it
in a data grid with no problem. In fact the the 6000 records I end up with are
the end result of some complex processing of 30 K objects of various types.
Sounds like your users want a plot of a plate of spaghetti.

I'm using a line chart. Using AMF3 to retrieve the data. The time it takes to
query the data, or transmit the data, isn't an issue. Also, the problem
doesn't happen over time, it could be the first request someone makes on the
application - I don't believe it's a memory leak.
The method used to populate the graph is thus:
var ls:LineSeries = new LineSeries();
ls.dataProvider = data[o];
ls.yField = counter;
ls.xField = dtime;
ls.displayName = o.valueOf();
if ( circleplots.selected ) {
ls.setStyle('itemRenderer', new ClassFactory(CircleItemRenderer));
}
var currentSeries:Array = linechart1.series;
currentSeries.push(ls);
linechart1.series = currentSeries;
Storing the data in an internal array, and possibly sending it to the clip
board isn't a big issue. It's trying to display that much data within a flex
construct that causes the problem(s).

If you need to actually round the number and use the rounded value in

[flexcoders] Re: create class on the fly
Just have your cfc return the results as a query, or as an array of structs. The first will be converted into an ArrayCollection of generic objects in Flex, and the second into an Array of objects. Each of these objects will have a property for each column in the record. Flex will be quite happy with these object and will let you do pretty much anything you want to do with them. You can use for (var key:String in recordObject) to get the property names. Since your queries are going to be dynamic you are going to have to process them dynamically and this is how you do it. You could also have your cfc return metadata about the result set, to tell you which properties are the primary keys, and anything else you need to know about the result to process it correctly. Having the server return objects that automatically get converted to typed flex objects is great when you know what type of objects are going to be returned. But if you don't Flex can handle untyped dynamic objects just fine, and you should use them when the results of a service can't be known at compile time. --- In flexcoders@yahoogroups.com, postwick p...@... wrote: I cannot predict at compile-time what the name (or properties) of the class will be. I need to CREATE the class at runtime, AND add the properties to it. It seems, so far, that this is not possible. However, what I'm doing sounds very similar to your project. It's not so much the sheer number of tables (although a few dozen) but the fact that the application allows the creation of new tables (so I need a new class) and columns (so the properties might change). I can easily have my app write new destinations to the config file for any new table created. I can even write the necessary CFCs to disk based upon schema changes within the app. But I cannot find a way to get the classes I need. All tables share the same foreign key column name, which is helpful. My idea is this...set up one class that has two properties - the foreign key and a second column. I would have one destination for each table, but all destinations will point to the same class. When my CFCs pull data, I will have them return the primary key along with all other data encoded (XML or something) into the second property. Then on the client side I can manage it by filling an ArrayCollection, then having a function that parses the actual columns and rows (from the second property) into a second ArrayCollection that my datagrid is actually bound to. Creates/updates would go in the reverse direction - placed into the second ArrayCollection and then processed up to the two-property format for the first one, at which point LCDS will take over.

One such component is a child of a child that is a peer of the login component.

[flexcoders] Re: No of Lines of Code
Simpleist case, use extended search in FlexBuilder and search for \n
that will give you number of literal lines of text in your project.
To get a little more complex you can search for \)$|\):\w+$|;$ as a
regex and get most logical lines in .as code. If you consider each
tag to be a line of code in mxml you could add |$ to the above and
get those.

I'm using the httpservice to make a call to an aspx page which runs a
query and returns the results. This is fine, but if I try to run the
same call again, the service is not actually going out to make the
call,
but rather just returning the results from the previous call. I know
this because the aspx page logs each call made to it. I always see the
first call, but no subsequent calls come through if I post the same
data. If I send a different set of data, the call works fine, but then
will not post that data again. Any ideas on why it doesn't want to
actually make the call? Below are the relevant pieces of code:

[flexcoders] Re: Cairngorm Model Locator
I assume that when a new window is opened you have an event that causes the data it needs to be loaded into the model locator. And you will probably have a check to see if the data is already loaded so you don't load it twice. Just keep track in the model of how many users there are for that data. When windows close or otherwise no longer need the data have them send an event that causes the counter to decrement. When it gets to 0 you can unload the data. --- In flexcoders@yahoogroups.com, gerhard.schlager [EMAIL PROTECTED] wrote: Hello!

The simple solution would be to destroy the data that a view loaded when the view gets closed. However, we are going to use flexmdi and it's quite possible that one or more MDI windows are using the same data. The only solution I've come up so far is to make the Model Locator aware of which window uses which data. Therefore it could free the unused data when no view uses it anymore. Yet, this could be a very error-prone solution. Moreover, I would loose the last bit of loose coupling. So, I'm not sure if that's a good way to handle this. Well, the Model Locator itself is often seen as an anti-pattern as well ... 2) Should I really put everything into _one_ Model Locator?

Hi, fellow coders!
I'm having an issue with an AreaChart when changing its *type* property.
There's a ComboBox that lets the user select how it wishes to see the
AreaChart (either *overlaid*, *stacked* or *100%*).
The method for this is as simple as:
areaChart.type = comboBox.selectedItem.data;
(I've debugged it and data holds the proper string required by the type
property).
My code is as follows:
mx:AreaChart id=areaChart
dataTipFunction=chartDataTipRender
height=100%
showDataTips=true
width=100%
mx:horizontalAxis
mx:CategoryAxis categoryField={dataSet.keyFieldName}
dataProvider={dataSet.dataSet}
labelFunction={dataSet.labelFunction}/

mx:verticalAxis
mx:LinearAxis
minimum={verticalAxisMinimum}
maximum={verticalAxisMaximum}/

mx:AreaSeries
alpha=0.8
dataProvider={dataSet.dataSet}

form=curve
showDataEffect=interpolate
xField={dataSet.keyFieldName}
yField={dataSet.valueFieldName}/
/mx:series
/mx:AreaChart
mx:SeriesInterpolate id=interpolate elementOffset=10/
You might wonder why I want to stack or overlay the chart, since it
has only
one series... well, the thing is more series may be added in
runtime, and so
it comes to play the area chart type feature.
So, whenever I change the AreaChart's type property, I get the following
error and stack trace:

[flexcoders] Re: Embedding String Variable in dataprovider name
For the immediate problem, add some code to the function that checks
the first parameter for null, and returns a null value of the
appropriate type in that case.
But for a more robust application, you should stop using lastResult.
Direct use of lastResult is really only appropriate for prototyping.
You are much better off using a result handler to process the result,
handling the special cases, and putting the appropriate values into
variables that you then use for the binding.

ActionScript doesn't have multi-dimentional arrays, but you can get
the equivelent by having arrays where each element is and array to
arbitrary depth. Also for associative arrays you should use generic
objects. So you can do the following:
var my3DArray:Object = {}; //this creates a new empty dynamic object
my3DArray[1992] = new Object(); //equivelent to {} take your pick
my3DArray[1992][Feburary] = []; or new Array()creates an new array
my3dArray[1992][Feburary][0] = someValue;
etc.
if you don't know if a key exists yet you can do
if (! (month in my3DArray[year]))
{ my3DArray[year][month] = {}; //create it if it doesnt exist
}

One v v quick question though. I'm using it for an app that has a number of modules that could be treated as standalone modules. They interact, but basically they are their own little thing (e.g. A contact management module, a job planning module). Using Cairngorm is it correct (and I know there is not right or wrong) to create each of these as widgets using the framework and sticking with the MVC style and then write code over the top to stitch it all together or is it better to look at the entire app as a whole and create it that way, I.e. have a ServiceLocator that holds ALL of the data connections, a Model for the entire app? The second way feels wrong, but I can't find anything about doing it in the modular way without writing code over the top (which I am more than happy to do - just my experience of writing loads of code and then finding Cairngorm is making me pause to see if there is something I'm missing).

[flexcoders] Re: Different DataTips for multiple series in one chart.
dataTipFunction is a property of the chart, not the series, so you
will have to have a single function that looks at the hitData to
determine which series the mouse is over. The hitData.element
property will give you access to the properties of the series that the
mouse is over. If you give the series ids, you can then have your
datatip function call your series specific function based on the
element id.

Flex requires variables to be declared somewhere in a function, but
doesn't care where it just rolls all variable definitions to the top
of the function, so there is a phantom var val:String; at the top of
the function. At the point where you call validateRequired val
exists, but hasn't had a value assigned so it is null which is what

No different than if you declared a variable without assigning a value

As long as you understand that and are are using it based on that understanding it shouldn't cause any problems. --- In flexcoders@yahoogroups.com, boybles [EMAIL PROTECTED] wrote: Is it possible to have a multiple AppModelLocators in Cairngorm...and if so, how best to implement them? For example, I have several apps in my directory structure: *Component1 -business -commands -control LAppModelLocator.as -model -view -vo *Component2 -business -commands -control LAppModelLocator.as -model -view -vo *Common -business -commands -control LAppModelLocator.as -model -view -vo Componnent1.mxml Component2.mxml Now I want to have common control,commands and business files to share among the different components, so I created the Common directory with a Common AppModelLocator. The command actionscripts in the Common directory structure use the common AppModelLocator bindings. So in component1 or component 2, I'd be using the local model locator bindings as well as the common model locator bindings in the same file like this: [Bindable] private var modelCommon : Common.model.AppModelLocator = Common.model.AppModelLocator.getInstance(); [Bindable] private var modelLocal: Component1.model.AppModelLocator = Component1.model.AppModelLocator.getInstance(); Is this going to cause problems? If so, is there a better way to do this? Boybles
[flexcoders] Re: Help - users having problem I can't reproduce
Thanks, I wish I knew what causes the error so I could reproduce it. I don't even know if thats the same error the other user got. I would guess it is a timing issue in the distortion effects code, with something happening out of order, but if I can't reproduce it I'm not likely to be able to figure out what. I'm going to replace the distortion effect with a standard effect and hope that works for everyone. --- In flexcoders@yahoogroups.com, generalxxaxx [EMAIL PROTECTED] wrote: I am getting an actionscript error: ArgumentError: Error #2015: Invalid BitmapData. at flash.display::BitmapData$iinit() at sandy.util::DistortImage/::renderVector() at sandy.util::DistortImage/initialize() at com.adobe.ac.mxeffects::SimpleDistortion/com.adobe.ac.mxeffects:SimpleDistortion::initDistortImage() at com.adobe.ac.mxeffects::SimpleDistortion/renderCorners() at com.adobe.ac.mxeffects::SimpleDistortion/push() at com.adobe.ac.mxeffects.effectClasses::CubeRotateInstance/::updateComing() at mx.effects::Tween/http://www.adobe.com/2006/flex/mx/internal::doInterval() at mx.effects::Tween$/::timerHandler() at flash.utils::Timer/flash.utils:Timer::_timerDispatch() at flash.utils::Timer/flash.utils:Timer::tick() This might account for what is happening with your user.

[flexcoders] Re: How to get the real X Y of a repeater item
The following code gets the x and y positions of an image that has been clicked on that was generated by a repeater. Getting the coords for a button should be pretty much the same. stageX and Y are the x and y coords of the mouse position relative to the application stage. mainCanvas is a direct child of the application and is the container that I want the coords relative to. If you have additional containers between the stage and the one you need coords relative to, you have to subtract the x and y at each level to get from stage coords to that container's coords. Subtracting the mouseX and Y moves the coords from the point or the click to the upper left corner of the image. selectedImage.x = event[stageX] - mainCanvas.x - event.currentTarget.mouseX; selectedImage.y = event[stageY] - mainCanvas.y - event.currentTarget.mouseY; --- In flexcoders@yahoogroups.com, zipo13 [EMAIL PROTECTED] wrote: Hi, In my app I create a repeater the generats VBoxes each with button in it.

[flexcoders] bug with showDataEffect and stacked columns
There appears to be a bug with using a showDataEffect with a stacked column chart. I have a column chart with a showDataEffect set to SeriesInterpolate. It works fine with a single data series or if clustered, but if I changed the type to stacked or 100%, it fails while rendering the effect. It fails in the filterCache method of NumericAxis which is called a few layers down from the effect play method. The problem being that the cache is null. Changing the effect to SeriesZoom gave the same result. I've added code that sets the showDataEffect to null when the type gets changed to stacked or 100% which keeps thing from blowing up, but I'd love to have the effect for the stacked charts.
[flexcoders] how to clear datatip
I have a column chart with drill down functionality. When you click on a column, it displays a more detailed chart for that item. The more detailed chart is in a view stack with the drill down chart so the main thing I do to get it to display is to change the selected index of the view stack. The problem is that the columns have datatips and when I switch to the new chart the datatip is still there. Any ideas on how to make it go away?
[flexcoders] Re: how to clear datatip
I had been trying that without success. It turns out after I changed the viewStack index, I called some code that turned the dataTips back on. So even though the code looked like this turn off datatips change view stack to display another component turn datatips on the datatips stayed on. I guess flex either never noticed that the datatips were off or updated the display of the hidden component just before displaying the newly active component. the joys of event driven programming. --- In flexcoders@yahoogroups.com, Ely Greenfield [EMAIL PROTECTED] wrote: That sounds like an unfortunate bug.

[flexcoders] can effect target selected item form list or repeater?
I have a photo gallery application. The initial view is of the first image in each gallery arranged in a grid via a repeater inside a tile layout. When you click on an image you get another view with a much larger image that runs as a slide show. I've got that working fine, but what I'd like to do is a transition effect where the selected image moves and resizes to where the slide show image is and the others go away in some way. What I can't figure out is how to apply one effect to the selected image and another to the rest of them. Any ideas?

That only happens it you are explicitly setting the scale for the charts. So if you just let flex adjust the scale to the data you'll be fine.
