Scroll error in AdvancedDatagrid in Flex 4.6

I am migrating an application from Flex 3.5 to Flex 4.6 . The mx:AdvancedDatagrid component which seemed to work fine displayes errors as shown below when I scroll fast . I am adding two more columns which has charts in them but this error seems to appear very frequently if I scroll faster . Please advice.
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Hi,
It's not possible to 'append' a StringItem or a TextField (or any other lcdui.Item object) to a Canvas or GameCanvas. You can only draw lines, draw images, draw text, etc etc, on a Canvas screen. So, you can only 'simulate' the look and feel of a TextField (on a Canvas) by painting it and adding source code for command handling (like key presses). However, this will be quite some work!!
lcdui.Item objects can only be 'appended' to a Form-like Displayable.
Cheers for now,
Jasper

Bizarre error adding Numbers in Flex 4

I'm having a bizarre error adding numbers in Flex 4. In all cases, I'm getting the correct result, but sometimes I'm getting extra precision with a 5 at the end.
For example,
If I try to add 5 and 1.56, I get 6.5600000000000005
a lot of numbers add correctly, it's just certain combinations that have the problem.

This question comes up all the time. It's a Fact Of life of modern microprocessors and computer languages, which implement floating-point arithmetic using binary fractions (1/2, 1/4, 1/8, etc.), not decimal fractions (1/10, 1/100, 1/1000, etc.), according to the IEEE-754 spec. Many decimal fractions, such as 1.56, cannot be exactly represented as a finite binary fraction. (Or the exact representation in binary might be finite but require more fractional digits that the spec allows.) Although your source program says "1.56", it gets compiled and executed as the IEEE-754 binary-fraction that is closest to 1.56, but it isn't exactly equal to 1.56, and then this slight error gets propogated through calculations, and the conversion back to decimal is again inexact.
Generally, people just use methods like toPrecision() to round things off a bit and hide this problem. Or they go write or find a (much slower) ActionScript library that does true decimal floating-point arithmetic by storing decimal fractions rather than binary fractions.

Portal theme switcher generates scroll error in RTL

Portal theme switcher using standard objects generates scroll error in RTL
Following the Blog for Switching Themes by Topic - A Color Code System for the Portal [https://www.sdn.sap.com/irj/sdn/weblogs?
blog=/pub/wlg/2053]
I developed a portal application and placed it in the page framework.
It works fine using Left To Right (LTR) languages but when using a Right To Left (RTL) languages like Hebrew and Arabic a long scroll appears in the lower part of the portal window and the masthead is moved a bit with no relation to the position of the other sections (iViews) of the screen.
I know its a custom development but it uses a standard SAP API.
The system version of the portal is NW 7 SP 14

Hi Yolanda,
it´s as you already figured out - 0FISCPER is the problem.
When you want to create new lines, there can not be a dynamic characteristic in the columns. Each column has to be defined with single values.
Try to create restricted key figures for the periods you need to show.

Error while migrating to Flex 4.5.1 (1067: Implicit coercion of a value...)

I am getting the following error while migrating my application from Flex 3.6 to Flex 4.5.1:
1067: Implicit coercion of a value of type __AS3__.vec:Vector.<Object> to an unrelated type Array.
The error is thrown on the following piece of code:
var list:ArrayCollection=new ArrayCollection(dgSoftwareTitles.selectedItems);
dgSoftwareTitles is defined as:
<s:DataGrid id="dgShareCategoryForTransfer"
x="34"
y="369"
requestedRowCount="5"
width="90%"
selectedIndex="-1"
selectionMode="multipleRows">
<s:columns>
<s:ArrayList>
<s:GridColumn headerText="SoftwareTitle"
dataField="idSoftware"
visible="false"/>
<s:GridColumn headerText="SoftwareName"
dataField="softwareName"
visible="false"/>
...more GridColumns
</s:columns>
</s:ArrayList>
</s:DataGrid>
Any ideas why this would trow the "1067: Implicit coercion of a value of type __AS3__.vec:Vector.<Object> to an unrelated type Array" error?
Thanks!
Lee

I think that dgSoftwareTitles.selectedItems is a type of Vector while
public function ArrayCollection(source:Array = null) expects an array as a source.

Error message when opening flex table graphic

Hello,
we're currently implementing our business processes in our CRM 7.0 SP3. This message is about an issue in the area the flex table graphics.
When trying to display it, error message "Error while loading data. Graphic is reset to its initial state." is thrown.
Steps for reproduction:
-) start any search in the web UI
-) In the result table, select "open chart"
-) Select any data to be displayed
-) The error message is shown
I found note 1416295, however, it doesn't deal with this issue.
Any ideas?

Syntax error when running GLPLUP - Flex Plan Upload

HI,
We want use transaction GLPLUP to perform a Flex Plan Upload, but encounter a syntax error in program RK50003 stating:
The following syntax error occurred in program "RK500003 " in include
"PP_FISL_GINC " in
line 652:
"The data object "ITDAT1" does not have a component called "XBILK"."
This program is a local object, and appears to be generated by SAP. Checking the program attributes the owner and the last person to change this program is a consultant who has rolled off the project, and is not available for help.
I suspect that there must be some steps to regenerate this code, but I am not certain where to look for this information.
I have tried running GLPLDEL and GLPLINSTALL, but this did not change RK500003.
Any insight you can provide on this is greatky appreciated.
Thanks,
Roy

HI,
I reported this issue with SAP and the following is what they had me do to resolve the issue:
1. Run transaction GLPLDEL:
Deletes all generated reports of the planning processor for
FI-GL/SL planning (application class GLU1). After a new call of
the planning, these reports will be generated once again.
2. Run transaction GLPLINSTALL:
It regenerates necessary database table entries for FI-G/SL Planning
(tables t8pl*). Make sure that you will perform this step when no
posting of FI-SL data is running.
This resolved the issue for us.
Good luck,
Roy

Issue with AdvancedDataGrid in Flex SDK 3.3

Hello Forum,
I downloaded and installed Flex SDK 3.3. Once I pointed my environment to the SDK 3.3, compiler complained that it can’t find AdvancedDataGrid component in the path. After some investigation, I was able to fix this issue by downloading Flex 3.3 Data Visualization Components from http://www.adobe.com/products/flex/flexdownloads/. Then I had to unzip downloaded file into the /sdk_3.3.0_install_dir/
I don't think I had to go through this in my previous installations - 3.2 and 3.1. Does anyone know the reason for this two step download and installation?
Also, I would like to use a new Vector class in my future development, does anyone know what version of SDK provides it?
Much Appreciated,
Mike

If I'm not wrong Vector is a part of Flash Player 10, so it's no related to the SDK, and also in Flex Builder you can access all the new classes that are available in FP 10 but you don't get autocompletion for those new clases if I'm not wrong.

Issues with Error #2048 on deployed Flex/PHP Web Application

Hello,
I'm testing out Flash Builder for PHP and I'm running into the following error when deploying to a web servers:
Send failed
Channel.Security.Error error Error #2048 url: 'http://testsite.dreamhosters.com/LocatorPHP/public/gateway.php'
I have looked though documentation and tutorials without any luck. My application works great on the local Zend Server setup but as soon as I jump to a remote web server I get problems.
Here's what I've tried:
1) crossdomain.xml in web root
2) amf_config.ini updated so zend framework on server and gateway.php are reachable (connecting to gateway.php directly gives me no errors)
3) attemped to change the flex server option in my project but Flash Builder for PHP will not allow me to change this, so I had to change my php service.as endpoint entry to the gateway.php on the webserver
Is there a log that can help me troubleshoot the error?
Thanks in advance.

Any solution I have just ran into the same issue. App works perfect on localhost phpmyadmin as soon I change everything to our public server ERROR#2048
I have tried same as above no results.

Capture a "scrolling" event in spark List (Flex 4)

after hours trying to find a scroller thumb drag event, i'm left stumped. Is ther any way to dispatch an event when the scrollbar of a List component is scrolling? or even better, to capture the scroll thumb dragStart and dragComplete events? thanks in advance -b

You could detect when the scroll position of the viewport goes sufficiently below zero and then call your refresh logic from there.
Here's an example of how to detect scroll position changes:

Send error from Java to Flex

I need to throw errors from Java and to receive them in Flex.
My idea is using xml with error id and message, and maybe the Flex
component which should show the error.
Is there any other way to do it? Another interaction between
Java and Flex?
Thanks in advance
Tuli-O

XML wrapping error info written to response when java code
throws and having a common component on the flex to handle this
situation -- maybe on the fault event.
