Using mathematical symbols in column titles -can't get it to work!

Hello all,
I am trying to use greek mathematical symbols in my column titles, ( Δ delta, ά alpha etc)
There is obviously some character set conversion problem/I need greek alphabet as the symbols are output as question marks on my JSP pages.
Does anyone know how to fix this please?
(I am setting the label text in the control hints section of the view object editor)
Thanks,
Louise

Include the Symbol you want in the control hint as an HTML encoding e.g δ or δ
Then in the page, go to the JSTL tag that displays the ${bindings[column].label} set the escapeXML attribute to false.

  • Targa files used to save paths, but I can't get it to work now.

    I've been using targa files to provide my marketing team with images that work in their space planning program that include transparency. I use an alpha channel to do this, and that part remains in fine working order. However, I used to save these targas on our network drive and they would retain paths we had created so we could easily select different parts of products and change the color for proposals the marketing team wanted to do.
    It's been a little while since this functionality has stopped working for me, and I can't for the life of me figure out why.
    They take substantial resizing after the fact, so just generating them from the PSD file every time is not an option. We still need the full size images from time to time anyway, and I'm talking about thousands of images. The size it would take on our network would make IT BM in their collective pants.
    Edit: I suppose I should say that I recently upgraded to CC, but I've been having this problem before then with CS5 as well. On a Mac, running Mavericks.

    I appreciate the reply. It's unfortunately not helpful for this problem.
    The sheer number of images we end up having to edit makes working on PSDs prohibitive, so we start and finish new versions of the products using only the TGA files. These files don't retain any of the channels created by masks in the PSD.
    When we have a product that has only one possible color, selecting the channel that we use for transparency works to grab the item for color correcting, but often times there are multiple parts to the product (wheels, handles, etc.) that need to be selected individually to create the color combinations marketing needs.
    I suggested to my coworkers that we could create channels for all the different features, but without testing to make sure this doesn't break the functionality in the space planning program, it's not something we want to try.

  • Help - using windows 7 and bonjour and can't get printer to work!

    Hi, I recently upgraded my wife's pc.  Previously I had a wireless printer set up using bonjour and the airport express.  My mac and the old pc (windows xp).  I had no problems printing.  I upgraded her PC and now it uses windows 7.  I installed bonjour and tried to print but no success.  The PC can see the printer.  It says that it sends the file to print.  I get no printer error or anything on the PC, but nothing happens.   Anyone have a suggestion?
    Thanks
    Kris

    on xp box
    1) install and start lpd daemon (done)
    2) set printer sharing (short name, no spaces) (done)
    3) make sure that xp allows tcp 515 (done?)
    on linux
    1) start cups
    2) open konqueror (not firefox) and enter in the address bar
    http://localhost:631/
    log in as root (I assume that basic cups with user is configured)
    3)select add printer
    - first page:set priter description
    - second page: Select device lpd/lpr host or printer
    - third page enter lpd://hostname/queue (hostname if defined in /etc/hosts, otherwise ip address of XP box queue -> printer share name
    - fourth page select manufacturer
    -fifthpage driver
    test it
    KDE
    K Menu -> Settings ->Printers ->Add -> follow screens
    I found KDE method (under Arch) more reliable, but both should work. No idea about Gnome.

  • Bought used ipo touch 5th gen but can't get it to work with my library

    hi bought used 5th gen ipod touch on ebay but it doesn't show in my library when i connect it all i get on the ipod is a message saying do you trust this computer when i prees yes nothing happens.

    Is your account listed in Settings>iCloud? If not y ohave to first delete the iCloud account from the iPod by going to the bottom of the screen. You have to enter the password for the listed ID. That is part of the Activation Lock

    Withou that or without getting the previous owner to remove the device from their account

    The iPod is not usable to you. If you can get either of the above two thnks done. restore the iPPod via iTunes and set it up with your account

  • HT4199 how do I fix it when "another device is using computer IP address" and I can't get wireless to work anymore? It used to work fine.

    How do I fix it when "another device is using computer IP address"? Airport used to work fine. I've already tried turning everything on and off several times.

    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
    Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
    Power-up your computer(s).
    If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
    Disconnect the AirPort base station from the Internet broadband modem.
    While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
    Continue with step 2 in the first set of steps.
    In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

    You can also remap the command to a single key:
    System Preferences, Keyboard, Shortcuts, Screenshots, select one of the options (like save picture of selected area), to an unused Fkey (I use F13 on my wired keyboard).  1 key screenshot.

    I am on Charter.net at my office and sbcglobal.net at home.

    check your outgoing port settings and make sure it's using a specific port and not the default port, also you might want to check to see if it is using SSL, TLS or any other encryption.  Verify the setting from your old machine setup.

    Any help would be greatly appreciated

    You are making some progress with setup of wireless network. Apparently there is reliability problem with the wireless connection. Perhaps you want to refer to following Apple support documents and start tweaking parameters in the router to improve the reliability. I used to have third-party routers such as Belkin and Netgear but switched to Apple Airport routers (Time Capsule then Airport Extreme for now) because of incompatibility issues whenever Apple upgrade Mac OS X. But since Apple develops Airplay protocol as alternative to Bluetooth for wireless audio/video streaming (with much better bandwidth) and must be deployed in any wireless network, there is no reason third-party routers not working for Airplay protocol.

    Thanks so much for the offer of help. I'm using 10.9.2 OSX. I have Numbers 2.3 (554). I tried the new version but it was "dumbed down" so much (to make it usable on multiple platforms) that it was of no use on iMac.
    I still can't get my contacts to open in Numbers like they used to do. I have a group of five addresses in a test folder in Mail called "untitled group." But no amount of pasting, dragging, etc can get them to open up in Numbers. My "real" folder has almost 100 addresses so I can't do it one by one.
    Thoughts?
    Thanks again.
    Bob

    Bob,
    You can place contacts in a table In Numbers by the following methods:
    Numbers 2.3:
    drag from contacts
    Numbers 3.2
    copy from contacts, then paste into Numbers
    In both cases you need to open System preferences, then select the "Security & Privacy panel and allow Numbers aaccess your contacts information.

  • I am using Numbers on my iPhone5 and cannot get the app to do a simple (SUM) calculation.  It shows the formula correctly in the cell, but all I get for my long list of numbers to add is 0.  How can I get this to work?

    I am using Numbers on my iPhone5 and cannot get the app to do a simple (SUM) calculation.  It shows the formula correctly in the cell, but all I get for my long list of numbers to add is 0.  How can I get this to work?

    Oaky, at least we got that far.  Next step is to determine if all those "numbers" are really numbers.  Changing the format to "number" doesn't necessarily change the string to a number. The string has to be in the form of a number.  Some may appear to you and me as numbers but will not turn into "numbers" when you change the formatting from Text to Number. Unless you've manually formatted the cells to be right justified, one way to tell if it is text or a number is the justification. Text will be justified to the left, numbers will be justified to the right.
    Here are some that will remain as strings:
    +123
    123 with a space after it.
    .123
