Subject: [flexcoders] Performance issues with data grid/advanced data grid



Hi All,

I'm loading an AdvancedDataGrid with an ArrayCollection of about 1350 items 
retrieved from the server. Each record has 5 fields, and I am using one very 
simple custom renderer. The grid doesn't seem to be able to handle these many 
records, and throws the following error:

Error #1502: A script has executed for longer than the default
timeout period of 15 seconds.

(I have attached the full stack trace at the end of the email)

I replaced ADG with the regular data grid, and experienced the same problem.

If I 'slice' the ArrayCollection and add only the first 1000 records, it seems 
to work (after some delay). The optimum performance seems to be with about 300 
records. I found a couple of work-arounds:

1. Currently, I set the height of the grid to be equal to the number of rows 
returned from the server. Scrollbars are turned off on the grid and turned on 
for the VBox that contains the grid.

If I set a fixed height for the data grid and turn ON the vertical scrollbars, 
the data renders correctly. I'm guessing that this allows the data grid to 
re-cycle renderers while scrolling and leads to more efficient performance. 
However, I don't want scrollbars on the grid, only on the parent container.

2. I can develop a paging implementation of the data grid, displaying about 500 
records on each page. Again, I would rather not do this.

Sorry for the long-winded post, any suggestions/workarounds to tackle this 
issue? Thanks for your help!

Hello,

I am creating a list where each list item has a variable number of child 
elements. the itemrenderer creates images for each of child elements. So a list 
item might have 2 or 7 children in a Tile layout.

AFAIK the standard Flex List control takes the height of the tallest list item 
and applies that height to all list items, which results in extra space 
underneath the items with less children to display.

What would be involved in creating a list that let each item determine its own 
height?

That doesn't work, it then creates the tooltip from the label value.

[flexcoders] AdvancedDataGridRendererProvider woes with Browser Resize

[davisford]

Hi I have an ADG with 6 columns.  3 of the columns have a custom 
AdvancedDataGridRendererProvider.

Everything works fine for me except when I resize the browser, the grid paints 
things in the wrong place.  Note that this is after all the data has been 
loaded -- although I understand the renderers seem to be lazily initialized 
(e.g. if you scroll down).

If I scroll up and down, I never see this problem.  I can only seem to make it 
happen if I really drag the corner of the browser all around and then scroll up 
and down.

Interestingly enough, I see this problem in my swf hosted in IE8 and Firefox 
3.5, but I can't reproduce it in Chrome for whatever reason.

I don't have really good insight on where/how to approach solving this issue, 
so I was hoping someone on the group might throw me some pointers on things to 
try?

Thanks in advance,
Davis

[flexcoders] Re: container layout performance: MXML or ActionScript?

[zaproheeks]

Thank you for your answer.

No question MXML can be easier. But is your layout static or dynamic? I.e. do 
you simply statically position the children in MXML and nothing else 
touches/moves them, or do you do a lot of repositioning / resizing / restyling 
of children depending on application logic right when you display the container?

Re: [flexcoders] NumericStepper and change event

[Richard Rodseth]

Turns out that this necessitates validation, and there doesn't appear to be
a way to access the raw text of a numeric stepper to pass to a
NumberValidator.

I started out with a NumericStepper (minValue 500)  in a form, and the
designer noted that the save button did not get enabled until you change
focus away from the numericstepper.

If I listen for keyDown and update the model, then you can't type "4000"
because stepper.value always returns something valid, so "4" results in 500.

Any ideas? I'm tempted to revert to a regular TextInput.

It seems like there should be a NumericStepper with built-in validation,
that fires valid/invalid events.

[flexcoders] using custom scrollbars

[Slackware]

Hi all, happy new year!!

I'm using a mx:VScrollBar to manage the scroll for a Canvas (with 
verticalScrollPolicy="off"), since I need to place the scrollbar off-setted 
from the Canvas.

This code works as expected (the canvas scrolls based on my vertical scroll 
bar):

MyCanvas.verticalScrollPosition = event.currentTarget.scrollPosition; 
//currentTarget is my VScrollBar

But this way, I still need to set the verticalScrollProperties "by hand". I 
mean, if I have a really big Canvas my scrollBar doesn't reflect the height on 
its thumb for example.

Is there any easy way to achieve this?

Many thanks.

[SPAM] [flexcoders] Re: how to open pdf, word file using flex

Hi,

Yes, you need to create a PDF template with Adobe Livecycle Designer with the 
relevant fields. Then your Flex app must send XML data to your PDF remote 
object (residing on the LCDS Server) with the name of the XML nodes matching 
those of the fields in the PDF template (for data binding).

I have written a number of recipes in the Flex Cookbook beta website about PDF 
generation.

[flexcoders] Flex Builder 3 Pro project preferences bug

[Joel Stransky]

I'm having the strangest issue with Flex Builder project properties.
If I right click on a project and choose properties, every section allows me
to make changes except for Flex Compiler. When I choose that section, the
'Apply' and 'OK' buttons dim out. Even if I don't change anything, choosing
another section pops up an error box entitled "Could Not Accept Changes"
with the message, "The Currently displayed page contains invalid values"

I've tried uninstalling/reinstalling Flex Builder 3 both with and without
removal of the settings file. I tried repairing permissions in Disk Utility
but nothing works.

Has anyone seen anything like this?

[flexcoders] Can I add icons to Checkbox filter?

[Thomas Silvester]

I ahve an ADG table with icons in some Columns as data , I was tring to add 
filtering for this columns , the text filtering works fine for columns which 
has String as data. Iwould like to add multiple filtering for the column with 
icons as the data, i can multiple filter these columns if i give the string 
value of the icon as the checkbox seleced value, but I want to add the icon 
itself to the checkbox filter insted of the String value of the icon and filter 
it , is this possible? Any help is appreciated.
 
For Example I have 
a checkbox with the image string value as "hicon1.png", "hicon2.png" etc and if 
i check or uncheck these valuse it is filtering correctly the icon columns , 
but I want to add the icon to this checkbox control instead of the above 
strings, how can i do that ? Also if I managed to add this do this filter the 
valuse as i select or unselect the icons?
  Ican not put the whole source since there are many files, but any idea on how 
to do this is appraciated.
thanks in advance,

[flexcoders] Text color on a Menubar

[Wally Kolcz]

Is there a way to control the text color of the drop down labels in a 
? I can change the top level with 'color' but it also changes 
the drop down label color. OR is there a way to control the background 
color of the drop downs?

My menu bar is a dark blue so I am using a yellow for the label colors. 
However, that also makes the labels on the drop downs (which are white) 
also yellow and hard to read. Thanks.

[flexcoders] Stop ToolTips from Appearing on Certain Buttons.

[taude1]

This seems like it should be easy. I know I can turn tooltips off with the 
ToolTipManager, but that's applciation wide.  I want to disable tooltips from 
certain Buttons.

I've implemented various combinations of tooltipShow, tooltipStart, 
tooltipCreate on teh Button and tried setting the toolTips to NULL, to creating 
a dummy toolTip, etc...


Any ideas on how to totally supress tooltips?

Thanks,

[flexcoders] Re: container layout performance: MXML or ActionScript?

[seanmcmonahan]

While I don't have any cold hard facts about MXML vs AS performance I'd wager 
that, all things equal, AS out performs MXML.

As far as my practice, I typically use MXML for layout and do everything else 
in AS.  Coming from a web dev/HTML background I find it very easy to visualize 
a layout written in MXML and feel that any lost performance (which is probably 
minimal) allows me increased productivity as a developer.

[flexcoders] Return Path/Type of Remote Object calls

[Dan Pride]

I am trying to trace the return path of a Remote Object call and a little 
confused by the result.
If I set up the following
 
   



and Call VehicleRo.getVeh(VehicleId)

What is the path in the debugger to find the result? It populates a grid just 
fine with 
ItemTypesRO.getVeh.lastResult

And should it come back as an Array of Value Objects or Generic Objects?

Thanks
Dan Pride

I believe you need to initialize the debugger.  Something like this (sorry, 
typing on my phone, don't have the code in front of me);

var d:MonsterDebuggrr = new MonsterDebugger(this);

where "this" refers to the application.  I'll doublecheck my setup when I get

[flexcoders] Re: XMLListCollection Filter - Viewing a single child branch

[invertedspear]

The Flex framework has awesome XML functions, even straight up querying of XML. 
I use this all the time: var myXML:XML = XMLVar.node.node.(@nodeID == 5) which 
will give you just this section of your XML


  



  


I'm not sure if this solves your problem exactly, but its pretty powerful stuff.

[flexcoders] Re: embed mp3 have error : unsupported sampling rate

[seanmcmonahan]

I ran into this not too long ago myself.  I believe the maximum supported 
sampling rate in Flex is 44.1kHz.  

Your code looks just fine, the mp3 is just "off".  Fortunately you can change 
the sampling rate.  I'm not an audio guy so I'm not sure of all the 
implications of changing the sampling rate, but it's what I did when I ran into 
this problem and it worked out okay for me.  I used Audacity to edit my mp3, 
it's a free tool for this sort of thing.

[flexcoders] Re: Flex Progress bar stuck....

[ag_rcuren]

Sounds like you are not letting the UI update during your 15 seconds of work. 
Flash player is single threaded meaning if you tell a progress bar to animate 
but then call a method that takes 15 seconds to finish the progress bar will be 
blocked until that method is completed hence your progress bar will hang until 
the work is done.

Take a look at pseudo threading or some other way to break up your work across 
frames that way you can give the UI some time to update and that should fix 
your problem.

[flexcoders] drop on list items

[ha...@rocketmail.com]

Here is a screenshot of two Lists I have created:
http://screencast.com/t/YmY2YWE2M 
The dataProvider of the "Glyph Sequences" List is nested within that of
the "Glyph tables" list.
Here's the basic structure of the data:  
Each of these Lists allow drag-drop. Normally the drag-drop of List
items is limited to within that List. I use the following (very simple)
dragEnter event handler to do that:
private function limitDropToCurrent(event:DragEvent):void{
if(event.dragInitiator != event.target){  event.preventDefault(); }}

I need to add the ability to drop items from the "Glyph Sequences" List
onto specific items within the "Glyph Tables" list and copy the data
being dragged to that specific "table".
What would be the best way to go about this?
Thanks,Harbs

[flexcoders] container layout performance: MXML or ActionScript?

[zaproheeks]

Given two "almost identical" (more  on that below) container classes one 
implemented in MXML, the other in ActionScript, which one is likely to be more 
performant? 

I'm not a Flex expert, but I know that even if MXML "is" ActionScript, there a 
number of things that are quite different. For instance, the layout of 
components is entirely taken care by MXML while in AS3 we have to do it by 
hand. Also binding is much more natural and common in MXML (stuff like 
property="{object.value}") while typically (at least in my code) I have no 
Bindings in my AS3 classes.

Another difference is that if some of the contained objects are affected by 
runtime conditions, since MXML hides away how the layout is actually performed, 
I end up doing adjustments on Creation Complete event, which will cause new 
re-render events. If I had implemented the class directly in AS3 I could have 
done everything inside createChildren() and maybe it would have been more 
performant?

What's your experience / best practices toward MXML / AS3 containers and 
conditional layout?

[flexcoders] Error(s) in "Passing multiple values back from an item editor" example

[mmyszew]

If the Flex 3 "Passing multiple values back from an item editor" example is run 
with the debugger, the following messages appear repeatedly.

warning: unable to bind to property 'State' on class 'Object' (class is not an 
IEventDispatcher)
warning: unable to bind to property 'City' on class 'Object' (class is not an 
IEventDispatcher)

In addition, If you enter a new city and immediately click the yellow 
background of the city/state cell, the new city doesn't show in the renderer. 
However, the new city is there if you get the editor to display again.

I'm a relative newbie and would like to use this example as a starting point 
for an application, but I hesitate to start with something that looks broken.

Your help would be much appreciated.
