Display object is read-only on the static Table

Greetings,

I create a static af:table in JDeveloper 11.1.2.4.0 JSF,.

temporally with 3 columns, so I can create rows and select data. When im to create as many lines and select data from all 3

Select a column of choice, to save on the different table using methodAction.

I do all the 3 columns can always be updated, but when im going to create a line, he throws me error in the table read-only.

Keep in mind that temporally static table have no primary key.

What should I do to work around this error?

Thanks in advance for any help.

See u object created by using wizard to only view real object?  Maybe that can be the cause...

  • Can we do a line read only in the advanced table?

    Hello

    We have an obligation where the user wants to the first line of a table advanced to readonly, and remaining lines as editable lines. Can someone please let me if we can achieve this?

    Thanks in advance.

    Hello

    Yes, you can set row as read only in the table in advance.

    Steps to follow:
    (1) take the attribute Transient seen as ControlReadonly (Boolean Type) in the attached with advanced table view object.
    Note: Your all the lines will have now a new attribute called ControlReadOnly.

    (2) using the property read only set SPELL on each field of your advance deposited the region.
    as ReadOnly ${oa.. ControlReadOnly}

    (3) the loading of the page, in the query itself process you can set the attribute to True and if you need frontline to travel up to the end of the rows in the table and set the value to False for ControlReadOnly.
    ex: line = vo.first ();
    row.setAttribute ("ControlReadOnly", Boolean.TRUE);

  • Several Applications using UDP Multicast Open (read only) on the same port

    Hi all

    Currently, I am trying to build a system that has the following architecture:

    RF Server = "1-9 A/D '-> «UDP Multicast (write-only) 1-9"»

    Workstation operator = "QTY (N) Data Display Apps all need independently to access one of the 9 UDP multicasts at a time.

    Essentially, I have 9 items of antenna that all digitized and distributed via UDP separate multicast address and port. On the receive side I need to be able to have the N number of data display applications where everyone can select the antenna element he wants to get data from. My current goal for N is 7 and the worst case for the data rate is 3.75 MSps IQ rates on each display.

    My question is whether or not it is possible to have several "UDP Multicast Open (read only)" on the same port but one by application Data Display? Also, are there limitations with this.

    On my local machine I tried a bit with the example 'UDP Multicast Sender.vi' and "UDP Multicast Reciever.vi". I created a "UDP Multicast Reciever2.vi" as another application that listens on the same port/Multicast address as the original receiver. No errors are thrown when you run the receivers and both receivers get the data string sent by the sender at the same time. Can I send data/a. 'PC'-> 'Router Ethernet'-> 'PC with receiver UDP N' reliable evidence? If so, that's fine, because it would be relatively easy to implement. BTW, I do not fear with occasional loss of data what is happening with UDP.

    If this does not work, I am also curious to know which deals with data deduplication. For example, two applications by subscribing to the same Multicast address and port does the router send two copies (which increases network traffic)? Or, the Windows operating system get a single UDP packet to the port and replicate in two independent applications?

    Below (or attached) are the two methods I thought. If multiple readers of UDP does not work so I thought I'd do a DataSocket "Data Distribution layer" between the incoming UDP sockets and display data on the workstation applications. This would add a bit of memory/processor to the PC workstation, but I know the DataSocket server of NOR can handle a sender unique multiple receiver architecture.

    Thank you

    Hi Tim,.

    The number of concurrent applications, get data on the same port UDP will probably be a limitation of the OS as well. If I had to guess, I would say that 7 of the applications should work correctly. In fact, the memory/CPU bottlenecks are probably the limit on how many simultaneous readers we have, especially since the capablities of PC hardware differ from one computer to the other. I doubt that the OS has a strict limit.

  • Convert editable PDF read-only when the Envoy in an email - JavaScript

    I have a real estate company that is trying to have an application that an agent and the customer can fill in the necessary information, press "submit" button, have the javascript code to compose an email with the attached pdf file.  Here's the question I'm having: I need to be able to convert the editable PDF reading only so that when the client receives a copy that they can not change the information again.

    Here is my code for the Send button javascript:

    It's the return of form e-mail. It is hardcoded

    to make the form comes back to the same address.

    Change of address on your form to match the code below

    Email business

    var cToAddr = " " [email protected] "; "

    First of all, download the customer email CC

    var cCCAddr = this.getField("1st_Tenant_Email").value;

    If (cCCAddr! = "")

    Download now the second email only if it is filled

    var cBenAddr = this.getField("2nd_Tenant_Email").value;

    If (cBenAddr! = "")

    Get now the third E-mail only if it is filled

    var cthirdAddr = this.getField("3rd_Tenant_Email").value;

    If (cthirdAddr! = "")

    Set text object and the body of the e-mail message

    var cSubLine = 'Test - form of contract '.

    var cbody = "thank you for submitting your form. \n' + 'save the attachment of the completed form for your records.

    Send the PDF as an attachment to an e-mail

    this.mailDoc ({bUI: true, cTo: cToAddr, cCc: (cCCAddr + ";")})

    (+_cBenAddr_+_";"_+_cthirdAddr), bassujetti: cSubLine, CMSG: cbody});

    I found a work around because I didn't buy something else. I changed the digital signature so that once it has been signed, it would turn into read-only except for the Send button. With the button send, I used the code above to submit the pdf now read-only for the company by e-mail and cc tenants.  I hope this will help others also.

  • Not set to read only on the files so that they can be shared and changed on a network.

    I've seen any other questions on this subject, but they do not solve my problem.  I had to reset my network because I have a new router.  Now I can open the files on my main computer from another computer, but they always opened read-only.  I tried to set sharing and security to allow the share on the network and allow network users to change files.  But I can not turn off the box next to 'read only' in the general tab.  I also tried to start XP in safe mode and take possession of the file (article 308421), but this does not work either.

    I also tried in vain to change the attributes of command line to remove the read-only attribute and to set the system attribute, use the following command:

    attrib - r + s drive:------------

    After trying a few other corrections, I finally did a system restore before the installation of the network.  Then, I used the Network Wizard to reconfigure the network. I changed the name of the computer, so I knew what was the new connection.  Then I copied the wizard network on a USB key and reconfigured the second computer.  Now everything works fine (I can open, edit and save files between computers) even if the readonly attribute is always highlighted on the record.

  • Files read-only on the network.

    Hello.  I use Windows 7 Pro 64 bit.  I have a home network with a second computer (Win XP pro) configuration.  My problem with my Windows 7 computer.  I can create and modify files it contains very well.  However when I access those files on the network, EITHER from the 2nd computer the same computer (which is connected to the computer 1, from computer1, via the network) they open read-only.  The curious symptom is that the files are read-only even when I connect to computer 1 to Computer1.  Any thoughts on this problem?

    -Files are not selected in their properties read-only.

    -There is only 1 account for both computers on the network, and this user is a member of the Administrators group.

    -This happens for all files.  I found an article about a known problem similar to Excel files.  I followed the instructions in this article, does not.

    -What happens when the files are located in C:\temp, C:\Users\\Desktop\temp and Documents C:\Users\Public\Public (supposed to be a shared folder).

    Any help would be great.

    Check the authorization/security.

    Problems of permission and security with Vista/Win7, check the following settings.

    Point to a folder that wants to share do right click and choose Properties.

    In the properties

    Click on the Security tab shown in the bellows of the photo on the right) and verify that users and their permissions (see photo below Centre and left) are configured correctly. Then do the same for the authorization tab.

    This screen shot is to Win 7, Vista menus are similar.

    The Security Panel and the authorization Panel, you need to highlight each user/group and consider that the authorization controls are verified correctly.

    When everything is OK, restart the network (router and computer).

    * Note . The groups and users listed in the screen-shoot are just an example. Your list will focus on how your system is configured.

    * Note . All the users who are allowed to share need to have an account on the computers they are allowed to connect to everyone is an account, that means a group of all users who already have an account now as users. This does not mean everyone who feel they would like to connect.

  • Copy the new Gmail message to a local folder in Thunderbird-, and mark it as read ONLY on the Gmail server

    Hi forum,

    for a long time, I tried to set up a filter which copies new messages in the Gmail inbox to a folder in local mail in Thunderbird, and defines in addition/unread state correctly on both ends.

    However, no matter what I try, it doesn't work.

    There seems to be no way to set the playback on the IMAP server to 'read' State after the copy action and at the same time keep the "unread" status for mails that have been copied to the local folder in Thunderbird.

    It does not work even if I created an intermediate folder on the IMAP server where mail is first moved to and only then is copied to the local Thunderbird folder later.

    I also tried all sorts of combinations with the 'move later' and other actions to FiltaQuilla.

    I'm really at a loss. I'm the only one who wants to copy the message from Gmail to a local Thunderbird folder and get the status of unread / read appropriate on the server, as well as in Thunderbird?

    Bunch help, thank you

    Bravo David.P

    Why is that every time I ask about any TB support forum, I find myself explaining things instead of getting an answer?

    I need to mail to stay on the server, even if I delete it locally. What part of this is not understandable?

  • cannot unset'read only "using the Properties window

    After a blip in the update, I have a lot of files in a folder that I am unable to fix it, because they are 'read only' and will not change using the unset opyion in "Properties".

    Here's what to do.

    FIRST: you sing in your Windows as an administrator. Windows 7 and Vista disable by default. In the menu START > Accessories, right-click on command prompt and click Run as administrator. In the command line type

    NET user administrator / Active: Yes

    (be sure to use the space before the slash). You should receive confirmation of success.

    Then go to the folder in question Properties dialog box and on the tab security add user everyone and give him full privileges.

    You should be able to access the folder as desired.

    Good luck!
