Variable not defined session immediately after CFSET session.var = "data".

Hello, everyone.

Got a real head scratcher (of least for me that is.)

Just to experiment a little, it is not (yet) project, but something I would like to as reusable code for future projects.

I try to write code that will clear session variables when the browser is closed, - THEN - separate session variables to the client by changing and expiring cookies cfid and cftoken.

In my Application.cfc, I have the following:

onSessionStart:
 <cfif NOT StructKeyExists(session,"app")><cfinvoke component="components" method="setDirs" returnvariable="session.app"></cfif>
 <cfset oRequest = getPageContext().getRequest()>
 <cfset session.cookies = oRequest.getHTTPRequest().getCookies()>
 <cfcookie name="cfid" value="#session.cfid#">
 <cfcookie name="cftoken" value="#session.cftoken#">
 
 onSessionEnd:
 <cfloop index="local.cookiename" list="cfid,cftoken,cfmagic"><cfcookie name="#local.cookiename#" value="" expires="now"></cfloop>

On the page that appears, I have:

<cfset session.cookies = getPageContext().getRequest().getHTTPRequest().getCookies()>
 <cfoutput>
 <cfloop index="idx" array="#session.cookies#">#idx.getName()# = #idx.getValue()# - Expires: #idx.getMaxAge()#</cfloop>
 </cfoutput>

The above is where appears the error message "Cookies" not defined in the Session  Didn't I just put session.cookies, twice?

Thank you

^_^

You can't.

To change a browser cookies, you must communicate with the browser.  This is done when the CF server sends the HTTP response for a request for this browser.

onSessionEnd() - by its nature - only works when it is not communicating with the browser, and has not been any communication from the browser at least the period [session timeout].  So you can monkey with the scope of the cookie all you like in there, but the changes are never sent to the browser, because the browser has long since "left the building" as it was.

HTTP is connectionless, and the browser is not communicating with the CF Server in any case (him speak only of browser on the web server), there is no way for the CF server know that the client has closed his browser.  Everything that takes place on the client machine, and CF is sitting on the server see  Even the web server does not know what is happening on the client user interface.

What you can do is to put the cookies and session to have a very short time, so that expire them quickly once there is no activity to refresh.

  • Element is not defined in the SESSION

    Anyone has an idea why a user of the site would get a message error "some element is not defined in the SESSION" and no one else? Whenever the user presses a page that calls a session variable from a previous page that has defined the variable, they get an error message of session. They get the same results with different browsers, IE and Firefox. ???

    The problem is solved itself. I don't know how. I scoured the user through a few test pages (which does not require a login) who comes to set a variable in session to text, and then on the next page shows the session variable. It has worked well. I thought: "maybe it has to do with the session during a connection.
    Then I put the test pages in a folder that requires a login and test pages worked. Then I had the user to access pages throwing error "undefined in session", after logging, and the error disappeared. I don't know what happened.

  • How to create a task that runs once a day, immediately after the opening of session?

    Hello, I'm wondering how to create a task using the Task Scheduler that runs once a day, immediately after I have logon.

    The reason is I want to use Bing Desktop to change my wallpaper every day. However, I just want to run the first time I start my computer every day, so it will change the wallpaper. By default, it starts whenever I have to logon. It's annoying, because I just want it to start once a day to change the wallpaper. However, using the Task Scheduler, I put only a trigger to start "at the opening of session' or"once a day." If I choose once per day, it runs about 5-10 min after I login, instead of logon immediately after. If I choose the two triggers, then it starts after each session.

    Basically, I just want the Task Scheduler to launch the program after the connection the first time I connect to the computer on any given day. How can I do this?

  • Discover 5.2 recompose pool linked clone - Wait for user to logoff - refresh immediately after logoff - connected on VM never reconstruct after the closing session or refreshment.

    Lets say, we have 20 clones related hen who has refresh immediately after logoff. 10 people are connected to VM 1-10. When plan us a restructuring of the entire pool, one would expect that VM 11-20 would recompose afterwards, as the newspaper of people out of 1-10 of Vm, the VM redial for the new replica. Instead, VM 1-10 are refreshing to a control point and recomposing replica ever again. It seems that when refresh after logging has not been defined, recompose work properly. These two elements are mutually exclusive?

    I guess that's what you're talking about?  http://KB.VMware.com/kb/2006707

    If so, Yes, this is a known problem, updating of log will cancel and replace a Redial on newspaper.  I raise this issue until I got was blue and you have heard that it will be corrected in a future version

    For now, I do it manually reconstructs in the pool > inventory tab > desktops (see composer details) > right-click on desktop > redial.  Usually, I do on a single desktop computer and let the replica to create and lots of then recomposed.  As recompose and selecting force their users to disconnect will do the trick also.

  • Level security line with session variables, not recommended?

    Hello

    We are on the point of implement security level line in our project of BI using OBIEE, and the solution that we found more convenient to our requirement was to use session with blocks of initialization variables.

    The problem is that this method is listed as "not recommended" in the Oracle documentation.

    Administration of alternative security options - 11g Release 1 (11.1.1)

    (This appendix describes alternative security administration options included for backward compatibility with improved systems and are not considered a best practice.)

    The Session Variables management

    Session system variables get their values of initialization blocks and are used to authenticate Oracle Business Intelligence users against external sources such as LDAP servers or database tables. Each active session of BI server generates session variables and initializes them. Each instance of session variable can be initialized to a different value. For more information on the use of variables and blocks of Oracle Business Intelligence session initialization, see 'Use of Variables in Oracle's BI repository' in Oracle Fusion Middleware metadata repository Builder of Guide for Oracle Business Intelligence Enterprise Edition.

    How confused... What is the best practice then?

    Thank you for your help.

    Joao Moreira

    authentication / authorizing the part is dealing with weblogic and then initialized the variable USER and you can use it for any initblocks for safety.

    Block of init to authenticate / variable session and authorization are different, I guess that you mix the two.

    Hello

    SoundCodec class is defined in Player 10. You use the Player 10 swc afcs? If so, you must change require Flash Player Version unser project-> properties-> Flex compiler in Flex Builder and that 10.0.0 and also ensure that your browser has player 10 and Flex SDK supports also the player 10.
    If you use afcs 9 CFC, then put 9.0.124 or something in the Version requires Flash Player and that should fix the problem

  • [AIR 3.0] New JSON feature does not work in Flashpromanager.new: Error #1065: Variable JSON is not defined

    After the upgrade of the AIR SDK 3.0 in Flash Professional CS5.5, I found a few problems.

    First of all, the JSON class in the library of as3corelib.swc get now a few compile errors:

    1061: call to a possibly undefined method decode a reference of static type Class.

    1172: definition com.adobe.serialization.json:JSON could not be found.

    At first, I was completely puzzled, because I had the good ' import com.adobe.serialization.json.JSON; ' reference.

    and I got the "as3corelib.swc" referenced in my ActionScript properties, so how that was not found?

    Then, I discovered that it is because it is in conflict with the new internal JSON class included in AIR 3.0

    (perhaps it should have been called something else, to avoid conflicts with the own Adobe as3corelib library).

    The new native JSON class's decode() method. It is now called parse()

    OK, so I tried to use the new class JSON, but after changing the decode() with parse() and removing

    the "import com.adobe.serialization.json.JSON; ' reference, Flash tells me that"Variable JSON is not defined.

    Really? The JSON class is displayed in the window pop-up Flash Builder code completion,

    complete with its all new parse() and stringify() methods! So why it say it is not defined?

    Also, my SWF file gets compiled without error at all, so that checks that the new 3.0 libraries are in place.

    I get the error "JSON is not defined" when running in ADL, not at compile time. Why?

    In order to spend in the AIR SDK 3.0, I've followed this guide:

    http://kb2.Adobe.com/CPS/908/cpsid_90810.html

    I know that this is on the upgrade to AIR 2.7, but I guess the steps to switch to AIR 3.0 would be very similar.

    only with the AIR3.0 SDK package, instead of 2.7.

    I also took care of type version = '13' in all the XMLs, instead of version = "12" as indicated in this guide, which is intended to 2.7.

    Also, I followed this advice on the addition of -swf-version = 13 in the properties of the project in Flash Builder window:

    http://blogs.Adobe.com/Cantrell/archives/2011/08/how-to-use-the-air-3-Beta-SDK.html

    But this does not seem to make a difference, because, even if I use Flash Builder for editing code (which is usually used for Flex).

    my project is a Flash Professional project, not a Flex, and when you test the project, Flash Builder works Flash Professional

    to compile, then run adl.exe (it's the same thing that if you click on the option "control / essay film / in the AIR Debug Launcher (Mobile)" within Flash Pro).

    In the window 'settings of ActionScript"in Flash Professional, I also have the good airglobal.swc referenced (from the AIR SDK 3.0).

    and the same airglobal.swc is referenced in Flash Builder as well (in 'referenced libraries') in order to get the correct code completion.

    I tried all sorts of things to try to make it work, but no luck. Still getting the error "JSON is not defined" when running.

    I'm getting desperate in this regard. I'll have to return to AIR 2.7.1 to stop wasting time on this issue.

    BTW, I also have another problem unrelated (though maybe it happens for the same reason as the other problem).

    Now Flash Builder says the method getTime() in my code, as if it was no longer a method of an instance of class Date.

    I have a line where I ask the timestamp like this:

    TS = new Date () .getTime ();

    Worked perfectly well until now with AIR 3.0.

    Now, when hovering the mouse cursor over the orange icon "(?)" appearing to the left, Flash Builder says

    "Access of undefined property getTime. Why?

    Documentation AS3 says nothing about getTime() get depreciated any thing of the kind:

    http://help.Adobe.com/en_US/FlashPlatform/reference/ActionScript/3/date.html

    In fact, in the completion popup code to watch as Flash Builder, now, it is not any mention

    set or get methods, as you can see here:

    http://img836.imageshack.us/img836/4793/dateinstancepopup.png

    I guess I can use property hung up instead of . getTime() but I don't know why I'm getting all the methods I had before.

    Any ideas why this is happenning? Especially the dreaded error 'JSON is not set.

    Well, after a lot of tinkering, I think I've finally found a way to finally make it work!

    I created XML files modified with the profiles required for AIR 3.0 and after many tries, it finally works!

    I downloaded here: http://www.mediafire.com/?d5e761frl5px4

    Here are the steps needed to get AIR 3.0 works correctly:

    1. Place the three files in the folder "c:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\Common\Configuration\Players.
    2. Then, make sure that you have unpacked the AIR SDK 3.0 in the folder "c:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\AIR3.0" do not crush the contents of the folder "AIR2.6", as suggested by the "Overlay AIR SDK" article (linked in the post above). He gave me problems. It is preferable to use another separate folder. My XML files are pointing to this new folder "AIR3.0".
    3. In the folder "c:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\Common\Configuration\ActionScript 3.0 ' create a new folder named"AIR3.0 ". Inside this folder, copy the "airglobal.swc" file located in "c:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\AIR3.0\frameworks\libs\air.
    4. Finally, you will need to keep the file "sample.xml - descriptor ' the ' c:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\AIR2.6\samples" folder, but change the attribute xmlns to 'http://ns.adobe.com/air/application/3.0'.

    Yes, you must change this in the AIR2.6 folder, even if the SDK has been in AIR3.0. It's because of the way the publication settings work in Adobe Flash. It is hardcoded in a DLL, so that cannot be changed. Is not very intuitive.

    I think the AIR SDK installation should be much simpler than that! I know that Adobe AIR is intended for developers, not for end-users, but yet, all these procedures upgrade not well documented are a pain in the *. I lost a LOT of hours in this (more than half a day), with what should be a simple update!

    Adobe should make an SDK installation if we do not have to be tinkering with all these procedures errors whenever a new update is released!

    Well, I hope that these XML files are useful to someone and avoid more frustration.

    Kind regards

    OMA2k

    PD: BTW, I still have the problem of. getTime() described in my post above, but it is not very important.

    because I can still use the property hung up. Yet, it puzzles me why this is happening.

  • Variable is executed twice and is &amp; quot; not defined &amp; quot; the second time around!

    Hello ~

    I have a weird problem at hand. I'm passing in a URL variable from the first page of one application to another. I know he spent properly on my second page, because I can get out. However... The variable is defined at the top of the page in the < head > tags, above and outside a < cfif isDefined ("form.submit") > cela... < / cfif >. The shape itself is in the body of the page. So when I navigate to the page of form, my variable displays, but then when I hit the button send answered me that this same variable is not defined, although it is not part of the function isDefined cfif and has already been correctly set when the page is loaded initially. What's a sense? Help, please!

    I'm having a little trouble after you on that since you are showing only pieces of your code, but...
    It seems to me that firmID is not the form. You do not show your form code, so I'm guessing.
    Can you confirm that formID is indeed a value inside the form tag?

    I highly suggest this scope you your variables. That prevents a lot of confusion and can make the code much easier to understand. Things like are really nothing, but might help.

    Once you get this figured out, I would also propose research using the tag.
