Interactive report will not save the BLOB column attributes

I created several interactive reports with the 4.0 and 4.1 which had columns of type BLOB with no problems and the download link worked fine. After 4.2 update, interactive reports get the following error when you click on the download link:
Not found
The requested URL /apex/apex_util.get_blob was not found on this server

If I open the edit page of the report, the BLOB downloads very well. When I looked at the report in detail the attributes of the BLOB column, I noticed that the BLOB column attributes had not been met. I tried several times to fill in (name of the Table column name, Primary Key, MIMETYPE, etc), but after applying changes and reopen the attributes page for the blob column, the values, that I entered is not saved.
For completeness, here is the select statement for the report:
Select "DESC_ATT_ID."
"BR_ID,"
"FILENAME."
"MIME TYPE"
DBMS_LOB. GetLength ("DESC_ATTACHMENT") 'DESC_ATTACHMENT '.
of ' #OWNER # '. " ALTEC_BR_DESC_ATT ".
WHERE BR_ID =: P3_BR_ID

Also, here is the value for the number/Date of the BLOB column format:
DOWNLOAD: ALTEC_BR_DESC_ATT:DESC_ATTACHMENT:DESC_ATT_ID

Can someone tell me please in the right direction to get the link to the interactive report work correctly?
Thank you very much
Jerry

Hello
How about you, you do not format BLOB column, do you it manually like this example here:

Apex. Oracle.com
workspace: somefeto
user: test
PWD: test
Application 63066

in the same workspace, there is Sample File Upload and Download (App ID 10540), and it works very well...

If not, Pls, reproduce the problem on apex.oracle.com

  • Firefox 8, will not save the username on some sites, is there I can to add a settings file manually?

    For most sites, FF8 records my login information. For some sites, it will not save my username. One site in particular, he used to be saved (I think that I added it to a settings file in an earlier version), but I deleted this user name for connection, and now I can't seem to save my user name.

    Is there a file somewhere that can be changed so that the username appears?

    Thank you

    The Web site may use autocomplete = off to prevent Firefox to record the name and the password.

    You can remove autocomplete = off with a bookmarklet to register the name and the password of Firefox.

  • Reader 9.4 will not save the completed form of Pro v8

    I just create a new form that Reader 9.4 won't let me save the changes are complete on.  She can only look at one, editing, printing, but does not save the contents of the modified form.  If I open it with Pro v8, it works fine.

    I opened some forms that I created some time ago, and they work fine - view, navigate, print, and save the changes.  It's just this new form which will not save.

    Is there a setting some part that I inadvertently set which is the cause?  My customer really needs this form, but it is useless if they cannot save the changes.

    Also, I will check the updates on my 8, and now it's the v8.1.3.  I uninstalled Adobe Reader and not reinstalled - no change.  It also does the same thing (not allowing not saved) on two different machines.

    Thanks in advance

  • Editable interactive report. To change the list column dropdown type filter.

    Hi all, I thought I had posted this, but I can't find my post, so apologies if it turns up to twice more...

    XE SUMMIT 4.2 11.2

    Ive created an editable interactive report... Everything works very well, and I have several Text, LOV and selection list columns...

    However when I now click on a column header to filter, sort etc drop-down list is the same format as the column itself. So if for example, I have a text box, then the drop-down list is also text boxes, if the column is a column LOV, the filter drop-down list is a list of fields LOV. (Im assuming this is correct behavior, because it simply inherits the column parent..)   So, I would change the lists to a list of standard display so that they are in order and can be used...

    I think so? I know I have to do, which is either to substitute the function that generates the dropdown filter... or probably more simply, write a bit of JS/JQuery that modify data for drop-down lists.  Im still to learn, some help would be appreciated...

    I think so. (and please correct me if I'm talkiing... garbage)   I need to find each of the appearance of the DIV with the ID that corresponds to the drop-down list box, and then loop through each entry and change the structure...

    Currently the source for drop-down fields resembles the following (for a text field...). :

    < div id = "apexir_rollover_content" >

    < a href = "javascript:void (false); ">

    < input type = "text" value = "24489" maxlength = size "2000" = "6" name = 'f06' > < / input >

    < /a >

    < a href = "javascript:void (false); ">

    < input type = "text" value = "N1021" maxlength = "2000" size = "6" name = 'f06' > < / input >

    < /a >

    < / div >

    How could I 1) browse each occurrence of div id = "apexir_rollover_content" on my page, so I found out about each other, how would I go through the list and change the line above an input to a standard list item text...? Or is there a simpler way to do it?

    Kind regards

  • Interactive report - how to set the default columns displayed

    Env: APEX 4.1

    For example, at the beginning, I created the reprot source as select c1, c2, c3 from t; later, I added c4. But I was unable to figure out how to do c1, c2, c3, c4 become the columns displayed default. I always have to click on Action-> select columns, and then move the C4 "do not display" to "report view". Any clue?

    Thank you

  • VPS Config will not save the password

    I am running 10.11.4 on what we'll call the Machine B and I'm trying to config a VPN which is supposed to connect to a Mac OS X Server running a VPN L2TP.

    Another machine, we'll call the Machine A, connects to the VPN without problem. So, I know that the problem is NOT server-side.

    So in sys prefs, you can access the network, and I have my VPN connection in there. Under authentication, I have two fields, one password and one for the shared secret.

    On computer A, when I go to look at settings, these two are saved correctly. This is why Machine A connects to the VPN without problem.

    On Machine B, I enter the password and the shared secret. I hit OK. If I click the authentication settings button once again, I see the points demonstrating the existence of a stored value of password and the shared secret. Then I click APPLY. Now if I click authentication settings, the password and the shared secret are empty!

    This happens again and again. I can't understand why. No wonder my VPN will not connect if this f-in computer won't save the authentication settings.

    Moreover, the VPN used to work perfectly without a problem. Then something happened - he asked me a password for my VPN unexpectedly. Never, since the VPN not working and I can't make it work because of this problem.

    Hello

    We discovered a machine here at our office today who had exactly the same problem. Your post was the only one I could find that describes our problem exactly.

    Our machine is a Macbook Pro, El Cap 10.11.4

    I found a solution that allowed me to recreate the VPN connection through the command line.

    Once the VPN connection has been recreated the shared key has been registered successfully in its field in the connection settings.

    This script https://github.com/halo/macosvpn saved the day.

    We use Cisco IPSec that is described on how to enter in the CLI to the bottom of the page, but L2TP is mentioned above.

    Good luck!

  • form created in the ES4 will not save the data entered in acrobat readerXI

    I created a big form in Live Cycle Designer ES4. If I save the form in pdf format and open it in Acrobat Reader XI I get the message that I can't save the data entered in the form only print it. All I want to do is to put the form on our web site for people to download, fill out, save, and send it to me. I consider another method that is if I distribute the form and take the distributed pdf and save it locally, when it is open in the player you get the Send button on the purple bar on the right side. This will confuse many of our users, so if there's a way to not have the submit button so that work, but how do I stop the send on the purple bar button?

    You must activate the reader of the form. You can do this in Acrobat 11 open the form in Acrobat and select: file > save as other > Reader Extended PDF > activate tools more

    11 reader can save non-active AcroForms (created in Acrobat Forms), but not the forms enabled for the XFA (forms created in LiveCycle Designer).
