Removed empty entrance of af: selectOneChoice on valueChangeListene

I use component af:selectOneChoice is filled with the values from the DB. When the page is loaded the first time, I can see a blank entry in this component. I have put on this valueChangeListener. When I change the value, the empty entry is deleted.

Someone can help me with the reason, or how can I keep this entry empty.

Good reading the documentation on the property of 'unselectedLabel ':

The label of the option that represents a null value, which means that nothing is selected. If unselectedLabel is not set and if the component does not have a value selected, then an option with a string empty as the label and the value is rendered as the first option in the choice box (if it is not an empty option already set). Once an option has been selected successfully, and if unselectedLabel is not set, then the empty option will not be made.

  • Remove empty lines in the merged table

    I'm looking for a script that will find and remove empty lines from a table that contains fields of fusion.

    I have a table of data with about 800 cases. This table is used to merge a page report which shows the various components of the employee's income. There are about 20 lines in the table and 5 columns. I apply the merge fields to a table in my .indd file and merging works perfectly. However, there are several features/components of income who share not all employees. Therefore, all pages of the 800-page report contains several blank lines should I have deleted so that the remaining data lines to snuggle up to each other.

    I need a script that will find blank lines in an .indd table and delete them. I found the script that did this and works perfectly on an ordinary table with blank lines. However, it seems that a table cell that contains a merge field (< < myField > >) is not necessarily 'empty', even if the data in this field is Null. I found that after the merger, I can highlight a blank line, press DELETE, run the script, and the line disappears, as needed. But it manually thousands of times would frustrate the purpose of the script. Also note that I've rubbed my data file to ensure that no hidden formulas, characters or spaces. The "Remove blank lines for empty fields" option does not work on the fields in the table (it seems to me. If I'm wrong, let me know).

    It seems that I really need script which will remove references to empty merge fields after the merger. I could run and then my other script.

    I have spent hours on this and hope someone can point me in the direction of a solution.

    Thank you!

    You can remove the markers of merge field by doing a search and replace of TEXT PLAIN for and replace it with nothing. That should allow your script to work.

  • How can I remove (empty) folders in Lightroom?

    After slaughter of the bad shots and do a bit of re-organization, I was with many empty folders.  "Withdrawal" in Lightroom takes them out of the catalog, but leaves empty folders on the disk.  Is it possible in Lightroom to remove a record catalog and drive?  At present, it seems like a two-stage process: delete the catalog, and then in the Finder.

    It sounds like a simple question, but I couldn't find an answer after spending a lot of time looking on the Web and poking around in Lr.  I found a few (older) posts on various sites/blogs help that suggests LR should remove empty folders automatically; This is certainly not the case for me.  Others said you should be able to delete a file using the context menu, then choosing Remove (any indication it works in Windows, not Mac).

    I use Lr 5.7 (creative cloud version); MacBook Air with OS X Yosemite; photos (where empty folders are) stored on a Synology NAS.

    Many thanks for any help.

    It is likely to be a problem of SIN/OS... delete an empty folder to my Synology NAS does not remove the folder, while if I do the same with an empty folder on a USB3 connected external drive the folder IS deleted.

    But Rob is also correct that the folder must be empty to remove the disc occurs.

  • Remove empty line in Selectonechoice

    My lov looks like this-

    I can't set value = 'first' I need the features as it is implemented now gets the current value selected by the user from the value field and I can't change that.

  • How to remove empty faces?

    Photos put a circle on it recognizes people faces. When I browse through the photos newly added, I put the name on some faces, and I delete the other faces by clicking X on the circle - faces for example on paintings or magazines.

    However the photo does not seem to remove these faces. They always appear in the function "add people", but with an empty box (light gray). For unknown reasons, there are two different shades of gray. These boxes list gets longer and longer, which "pollute" the list of recognizable faces but without a name.

    If 'add you' one of these for a list you of people, you can't put it back to the people without a name. You can hide only.

    If you double-click it, you get the usual screen that should show photos belong to that person, but it is of course empty... expect a wheel that turns without end. If you click the link to find more pictures of the same person, you get another screen, saying he has none. And this time the screen displays again the original face that I removed by removing the circle on the picture.

    I wish I could just remove a recognized face so that it is no more displayed in the "list of people" and in the "add people" list How can I do?

    At this moment I have not found any way to remove thumbnails of empty people.  I just have them merged into a people album called delete and hide this person until this whether an update will fix it.

    I tried if helps to repair the photo library, but it has not fixed the empty tiles. The only result was a new download of the library to iCloud.

    If you hide people without removing the circle of faces of photography, photos of this person may not be used in memory. You don't want that, if there are pictures, you want to use in the memoirs.

  • Remove empty space under tabs

    There is a persistent empty bar under my tab bar. Cannot remove through customization.

    The address bar and the button menu '3-bar' has been to space before you moved them to the menu bar? Do you use the extension classic restaurateur theme?

    If Yes and Yes, I think you need to find the checkbox in the options of the CTR to remove the Navigation toolbar, since there is no built-in way to remove after removing the icons.

  • How to remove empty lines of chain between the relevant data?

    I have problems with the removal of empty lines of final my data output string.  I know this is simple to do, but I'm stuck in the same train of thought.  The file is a converted hex file that is written in a series of recordings.  Convert lines it is result in fa all that data should be deleted and the number of records adjusted accordingly.  I have the code to take the file, convert, delete all of the records with F and adjust the number of files, but I'm left with a gap in my file no matter my approach I can't remove the empty spaces regularly.  I have attached the file with spaces and the goal is to remove the spaces between the blocks of code, and spaces is not always in the same direction.  Thanks for any help.  If needed I can join the code I already developed if necessary.

    Darrick

    You can read the file line by line and write back only if the length of the string <> 0.  (or maybe <> 1 in the case of the character line appears in the string to a blank line.)

    However, there is probably a way to change the code you have now so that he does not write blank lines.  Without seeing the code, it is difficult to help.

  • How remove &lt; empty Menu &gt; when click on the menu button?

    Hello

    In my makeMenu() application method, I use menu.deleteAll () to remove all of the default menus. If I run this code in 9530 (storm Simulator), it shows only to see the keyboard and button application menu, it's good.

    But if I run the code in other simulators it shows .

    Where the focus is anywhere in the screen, it shows the empty menu when I click on the menu button. I need to remove this also.

    What I want, if I click on the menu button, it should not show anything (means it should not show , but in the storm if I click on the menu button, it should show (show the keyboard application and switch).)

    It is anyway to solve this problem...?

  • Script to find and remove empty elements list ListBox

    My form contains some items added to a list box by the user of the form.

    I need a script that loop over the list of ListBox, find and delete all the elements that appear as empty (can click in the same row, but no text is displayed).

    You may need to change this option a bit according to your needs: he is not catching the items in the list with a blank space.

    var lbList = xfa.resolveNode("lbStuff.#items");
     for (i = lbStuff.length-1; i>=0; i--){
      if (lbList.nodes.item(i).value == "") lbStuff.deleteItem(i);
    } 
    

    I tested with a list box "lbStuff" container "15", "", "", and "16" as a value. This script removed the "", but left the "". "" So if it is possible for the user to add an element with spaces and no text, it will have to be changed a little.

  • Remove empty columns

    I have the following columns:

    address2

    Sometimes address 2 will be empty, because there is no data for this column. I want to be able to remove this empty space he leaves because of no data. I tried all anchor objects, then choosing their collapse, but that doesn't seem to work for me. I don't know if there is something more to him while cela or not. If Yes, could someone please tell me what I need to do? Is there another way to make the blank spaces to remove? Any help is appreciated, thanks!

    Hello

    If you want to make the address 2 hide column, make the vertical elasticity of the field address 2 variable value. For if the value exists in the database, it will show the address or if not the Address1 will be combined with city | State | Details of the country.

    On the other hand, you can opt for a conditional formatting to hide the column when the value of address 2 is zero.
