Tricky issue with $FLEX$

Hi All,
I have a concurrent program with three parameters(say A, B,C)
My requirement is to
a) derive B using parameter A (I guess it can be done using $FLEX$)
b) dervice C using both parameters A, B
Is it possible to use $FLEX$ to fetch values of both A,B parameters.
Could someone please assist.
Regards
Kiran

I think you can do that. As when you flex you give value set name along with it. So you should be able to write in the query with $FLEX$.VALUE_SET1 and $FLEX$.VALUE_SET2
I think it should work

Issue with flex lifecycle

I am trying to address an issue with flex lifecycle
There is a ui component ( say CompA) comprising of multiple tabs with individual components used in each of them.
CompA uses a data object that is used to populate the fields.
On click of a button in another panel, I am setting the current state of the application to this view component and after CompA is completely rendered I would like to load the data object and populate the fields.
The issue here is I cannot use the creationComplete event of CompA to load this data object because at this time not all components are completely created. (creationComplete of each of those components is not completed yet),.
When exactly can I load this data object into the UI fields. I am not able to figure out where even callLater() can be used .
applicationComplete
Event doesn’t seem to be an option, in this case.

You can load the data when the state changes. There are events for that.
You could also look into updateComjplete which may work for you.

Tricky Issue with connecting to Lync server from my desktop lync client 2010

I am facing a tricky situation here,
Firstly i have 3 modes of connecting my laptop to the internet as follows:
1)Using Wi-Fi connection.
2)A physical LAN cable connection
3)An internet data card (A USB data card).
Now, i can comfortably use my Lync using 1st and 2nd mode of connectivity. But i am having a real issue using the 3rd mode of connectivity i.e using internet data card, it just doesn't connect to the Lync server at all, even though i can browse internet
very well.
Later i got a workaround to solve this, what i did was, i connect to internet first with 1st and 2nd modes i.e wifi or lan cable and then i also connect to internet using 3rd mode i.e data card.
After this i start my Lync, which now connects perfectly and then when it is connected and working.
I disconnect my WiFi or LAN cable this causes Lync to restart, but this time it connect within minutes again using internet of my datacard, isn't this Bizarre ??
Now Could someone please help me to connect the Lync just by using my internet datacard?
Atlast 2 thing which may be of help is :
1)I can easily connect Outlook to the exchange server using my datacard and retrieve my mails.
2)When i connect to internet using my internet datacard, I can still see "Not Connected Symbol" in my network indicator on my Win7 PC, But i can still Brows
internet.
This problem may have something to do with networking, not sure. Please Help me to solve this !!!

Infact it was a Network Issue, found following on technet and solved the issue:
I found a solution for (my version of) this problem. My tray icon never showed the red X, but if I clicked on the icon, the popup showed a bigger icon with a red X, and said "Not connected". As in your case, Internet worked, but I'm unable to setup
a VPN connection because it insists on using a non-existent modem, obviously because I'm "not connected" (which I am).
I monitored the processes running the NlaSvc and Netprofm services (using ProcMon), and noticed that both were denied read/write access to subkeys within the HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList hierarchy.
The processes were running as NetworkService and LocalService, respectively, so I tried adding full access for these service accounts to the entire subkey
mentioned above. Notice that permissions are not automatically inherited in the registry, so you may need to explicitly "replace all child object permissions with inheritable permissions from this object".
Within seconds, Network and Sharing Center tells me I'm connected to my domain. Yay!
A reboot was required to fix the tray icon and its popup.
However, I'm still unable to add my VPN connection.
I'm interested in hearing from you guys if your registries miss the same permissions? If so, Windows 7 must have a bug somewhere with misaligned service permissions/rights.

Issue with $FLEX$ and populating dates.

Hello,
I'm creating a custom report for a HR report. I have a requirement to enter a report type, if that report type <> 'DATE' then the parameters to enter dates are to be disabled. I when through the following steps.
Steps:
1. Define controlling parameter, XXRPT_TYPE
2. Define parameter - P_HIDDEN_PARAM. As it's name suggests, this is a hidden parameter, which will not be visible when we submit the conc. program.
Set it's Default Type as "SQL Statement " and
Default value as - "select decode(:$FLEX$.XXRPT_TYPE,'DATE','Y',null) from dual".
3.Define custom valueset, which will used for the date parameters - " Date From" and "Date To".
a) Click on Edit Information and enter forllowing query in Table Name field.
(SELECT (TO_DATE (SYSDATE - 200 + LEVEL, 'DD-MON-RRRR')) date_range FROM DUAL CONNECT BY LEVEL <= 1000)temp_tab
I am using "CONNECT BY LEVEL" concept to produce dates with the range of 1000 days.
You can modify 1000 to any other figure as per your requirement.
b) Set Value Name as date_range, which is nothing but the alias name in the query above.
c) I Entered following WHERE clause in Where/Order By field.
WHERE :$FLEX$.AMS_SRS_CHAR50='DATE RANGE'
When I run the concurrent program, the date field will disable if the report type will is on something other than Date Range, however when the report type is date range, I get an error (No Entries found for List of Values) If I comment the where clause then the date are displayed, but the disabling doesn't work. Does anyone have any ideas for me?

not sure what do you want but

I followed a link on http://stackoverflow.com/questions/2354891/flex-profiler-doesnt-do-anything and updated the mm.cfg file didnt help either. Can any one help me with this?
Thanks.

Reboot. Make sure debugging works. Then try profiling again.

Issue with Flex field context value

Hello all,
I have changed the seeded flexfield context segments to customize based on our requirement for the "Additional Period of service" DFF. It looks good but the segments still point to the old value sets validation. Please advice how to fix it.
thank you

Hi Kalyan,
Just check out if some kind of conversions are possible. You haven't specified the type of the parameters - both the search help parameter and the screen field parameter. Specify that too.

We are trying to automate Flex web application using QTP10.
We are facing below issue with Flex tree when we try to automate a scenario of selecting a child item displayed in flex tree.
Issue:
On recording the step of selecting an item from Flex tree using QTP, the script displayed is .Select Index1. But when we replay it back no action is being performed.
Also on object spy we are able to navigate only till flex tree and we are not able to spy child items of flex tree.On the web page the child items are displayed as radio buttons/checkboxes.
Please provide a solution for me to this problem.
Thanks

Hi,
You could perform a HTTP trace (using HTTP watch) and compare the OCI data in POST method for both users (the correct and incorrect ones).
Perhaps there is some additional/missing information being passed from catalog to SRM.
Kind regards,

Issue with graphics tearing on thumb scroll in Flex 3

We are seeing some off issues with graphics (one using the charting package and the other using degrafa) tearing on thumb scrolling in a large Flex 3 app. It's very hard to reproduce on OSX with the latest versions of Safari and Firefox, but it shows almost immediately when you run the app on Windows or Linux (regardless of the browser). I took one of the pieces out of the app and put it into a very simple testbed app and can't get the problem to show on Windows (i was hoping to isolate the issue in a smaller test case, but no such luck).
So, ii've got a few idea's on how to work around the issue, but i was wondering if anyone else has seen this type of problem before?
Problem:
     - graphics tear on thumb scroll
     - doesn't happen if you click in the track or use the arrows
     - one view is using the charting package, the other view is using degrafa
Thanks for any comments or suggestions...

Flex Module issue with Panel

Hello everyone. I have the following problem.
In my application I have several modules and each of them have components CollapsableTitleWindow (extends Panel). After opening the window it is added to the container which is in the main application (CollapsableTitleWindowContainer). In these windows you can open another window (and so on).
Now, what is the problem. When I change (reload) any module and I want to open a new window (sub window) with the already loaded window I get this error:

override protected function layoutChrome(unscaledWidth:Number, unscaledHeight:Number):void

                if(!(mx_internal::titleBarBackground is TitleBackground)) {
                        mx_internal::titleBarBackground = new TitleBackground();
                super.layoutChrome(unscaledWidth, unscaledHeight);

Issues with file upload in flex mobile application (sharepoint as backend)

Hello,
I am working on flex mobile application for android platform for which we are having sharepoint as a backend.
(Flex SDK 4.6 and AIR 3.9)
Issue which we are facing is as follows:
We are communicating with the backend server using webservices: example:
<s:WebService id="kWebService" wsdl="http://www.kservice.net/kdatabaseservice.asmx?WSDL" >
            <s:operation name="AddPost"
                         resultFormat="object"
                         result="addPostResult(event)"
                         fault="postsfaulterr(event)" />
</s:WebService>
Above services are working fine but we are facing issue with one service which is related to file upload.
File upload for <10 MB is working fine but when we try to upload larger file on server it fails to process.
We are sending bytearray to the backend and backend code is writing those bytearray into file.
We have tried many ways to overcome from this situation. like we have checked configuration for file upload size on server , we have tried wcf services as well. Please help us on this criticle point as soon as possible
Thanks

What do you mean that my video saves the contents int he server and not in transparent table? I save the data into a temporary database table so it can be accessed by the parent WDA session. From there the WDA session can do whatever it wants with it. What do you mean by transparent table - that would be a database table. Do you actually mean internal table? if so, just read the data from the temporary database table into memory.

Flex file upload issue with large image files

It is only coming in Windows 7 systems and the root of this problem is SSL certificate.
Workaround for this:
Open application in IE and click on certificate error link at address bar . Click install certificate and you are done..
happy programming.

Any issues using ALCS with Flex 4?

We're about to move some of our code base to Flex 4, and I wanted to check in advance if there would be any issues with ALCS using Flex 4 Beta 2 and Flash Builder Beta 2.
Thanks,
Rick

Hi,
If you are using player 10 ALCS swc and Whiteboard with Flex 4 and Flash Builder beta 2, it might throw an exception sometimes which has been fixed recently and will be updated in the next drop.
Player 9 ALCS swc should work fine. We haven't done testing extensively on Flex 4 for our framework, so if there are any issues that you come across, please report to us.
Thanks

Ideapad Flex 14 issue with Windows 10

Now i upgraded it to windows 10 and everything went ok but both Wired internet connection LAN and Wireless internet connection was not working. I have downloaded the drivers by myself and also what Lenovo support suggested but it is not working. Has anyone with Lenovo Flex 14 upgraded to Windows 10 successfully. In some ways Lenovo was advocating to update to windows 10 but they don't want to help me but send me to premium support where i have to pay :-( Thanks in advance for any help.

This really is a driver issue with Nvidia SLI or not, but it has to do with this monitor and possibly it's 75Hz refresh rate. I thought I'd share and hopefully Acer can work with Nvidia to make their new monitors compatible with Win10. I know we are using bleeding edge tech here, I don't mind doing the troubleshooting as long as someone acknowledges the issue and will fix it. Serious memory leak with 355.60 as soon as the monitor goes to sleep. I've done extensive testing with poolmon, xperf, etc to see if any other drivers cause this, but nothing, this is a brand new win10 fresh install. Easiest way I can show this is via MSI afterburner. Monitor is set to sleep after 1 minute so I can do this quick test. You can see less than 2 minutes in, pagefile usage already jumped up 4gb.Unless I wake the monitor, this will eventually eat up all virtual memory resulting in:

I'm having issues/glitches with Flex Pitch

When I analyze any vocal track with flex pitch, It messes up quite a few of my notes and tunes with weird buggy sounds,skips & stutters.
sometimes with gargly noises as well. When I decide I just won't flex pitch that area and delete the flex pitch, it's already messed up my track and won't go back to sounding normal. I want to know how to get rid of it! or at least how to fix that problem. even if there's an easier way to just actually delete it. I've even tried to make a seperate track for just the vocal parts that are haing issues, but it's still there when i move it. I feel like it's corrupt my vocal track and i'd like to use to one i already have instead of rerecording all the time .
Any help would be greatly appreciated
Here is a small sample of my problem in the vdeo link below and one of the smaller glitches. it's very noticable when the whole track is playing too.

Same issue for me. Has happened on different projects and different kinds of tracks (vocals and guitars)

Flex RSL issue with SDK version change?

Hi Friends!
     I am facing very crucial common problem when using Flex RSL feature.
Problem: My Custom component library is compiled with Flex 3.0 and more than 50 applications are using it. Now some of our new applications needs to use the features from Flex 3.2 SDK(like increased control width and height) and those controls should also be in same library.
So, the library should be common for application which are using 3.0 as well as 3.2.
My requirement is
"Without recompiling all Flex 3.0 applications, I need to run both Flex 3.0 and 3.2 applications using library compiled in Flex 3.2"
now I am getting some errors like,
     Error #1063: Argument count mismatch on mx.core::CrossDomainRSLItem() -- from systemmanager
     VerifyError: Error #1053 -- mx.managers.SystemManagerProxy.
     ReferenceError: Error #1065: Variable _*_mx_managers_SystemManager
Is it possible to win this?
I hope flex is having backward compatibility.
Please help me on this.
Thanks,
Ananth.

The only cross-version compatibility is called the Marshall Plan. It is described on the open source wiki and on my blog.
