  • Get the display values of a multi selection listbox

    Hello, I am creating a visual jsf project and I have a multi selection listbox component. I have bound this component with a table of my database. For the value of the listbox's items I use the "id" field of the table, and for the display value I use the "name" field. I know that with the method getSelectedValues() I get the values "id" of the listbox, but what I want is to get the display values of the selected items of the list box. How do I do that?I have tried this code:
    Object[] selectedareas=getSessionBean1().getAreas();
    String[] mySelections=getSessionBean1().getAreas();
    selareas=areasDataProvider.findAll("id", selectedareas);
    for(int i=0;i<selectedareas.length;i++){          
    some= (String) areasDataProvider.getValue(areasDataProvider.getFieldKey("are_name"), selareas[i]);
    but I get an java.lang.ArrayIndexOutOfBoundsException: 0 error. Any suggestions?Thank you in advance!

    The way I get it in my <f:selectItems> is by binding my multi select listbox, with my database. So what the code is on my jsp page is:
    <f:selectItems binding="#{addcases.multiSelectListbox2SelectItems}" id="multiSelectListbox2SelectItems"value="#{addcases.languageDataProvider.options['language.id,language.lang_name']}"/>and I don't know how to work from here..

  • Items are not visible in multi-select listbox in a static form

    Hi,
    I'm using adobe livecycle designer 8.0. I have a multi-select listbox, the items are hardcoded into the form. In runtime, some of the items are selected from the server side when the PDF is generated. If only one item is selected then there is no issue. When multiple items are selected, the list box is behaving as below.
    If the PDF is static,
    If the listbox is readonly, then all the selected items are visible (highlighted in red)
    If the listbix is editable, then it appears blank. If you select it using right click, then you can see all the items and the selected items. But if you click again somewhere outside the listbox, then the listbox goes blank. If you select it using left click, then the previous selections are gone and the items are visible with the item you just selected.
    If the PDF is dynamic, then the multi-select  is working fine.
    Aren't the multi-select listboxes supported in static PDFs?
    For your reference, I created 2 templates (static and dynamic) and populating the values using javascript in the docReady event. I'm using \n character as delimter to select the multiple items. Please find them at the below links.Notice the "List Box 1" in both forms. In static form, the values appear only after you right click the listbox.

    Hi All,
    In such cases, please try to check as below :
    1) Create Leave request work item from Employee and check the same under the UWL Tracking tab of employee.
    2) Log-in to swi5 transaction of the respective back end system and give "US" -> manager's UserID -> Choose Tasks to be completed from the drop down -> Remove any date if mentioned -> Execute.
    3) Here if you can see the Leave request created, but not on the portal, it reflects some portal issue like sync.
    4) If no leave request work item is seen here, then there is a problem in the employee manager mapping or the workflow setup.
    5) In such cases, you can try to check the Swi1 and check the log of that workflow to understand the current status of the Leave request.
    Revert if further help is needed with more info.
    Reward points if found useful.

  • Multi Select Listbox - Horiz Scroll Bar available?

    I'm using the Standard - Multi Select Listbox and would like to see a horizontal scroll bar on it down at the bottom when the contents are too long to display in their entirety (and many of my items in the list start off the same with the distinguishing text at the end of the line).
    What's puzzling is that in the JSC IDE Design Tab, when I set some of the Default items to a long string, the control is shown on the Design Tab WITH a bottom, horizonal scroll bar! I was so hopeful! But when deployed the vertical scroll bar is there, but the Horiz scroll bar is gone :-(
    Has anyone gotten a horizontal scroll on a Multi Select Listbox to work in Creator??
    Suggestion to Creator Team: Please add a horizontal scroll bar OR at least allow a cursor on items in the list so that the user can manually move thru the line to see what it says.
    Thanks!

    Please help -
    These work arounds don't work for me. I'm using the latest Creator2 with all updates applied. Any chance of seeing a property for this soon?
    Work around 1:
    ===========================
    <div style="height: 72px; left: 144px; top: 192px; position: absolute; width: 288px; overflow: auto;">
    <ui:listbox binding="#{weblinkpl_page1.listbox1}" id="listbox1" items="#{SessionBean1.listOptions}"
    onChange="common_timeoutSubmitForm(this.form, 'tabSet1:weblink_tab2:layoutPanel2:listbox1');"/>
    </div>
    => Gives me listbox with no width at top left corner of page. Populating with very long file, changes the width of the box rather than creating a scroll bar.
    Work around 2:
    ======================
    <div style="overflow: auto;">
    <ui:listbox binding="#{weblinkpl_page1.listbox1}" id="listbox1" items="#{SessionBean1.listOptions}"
    onChange="common_timeoutSubmitForm(this.form, 'tabSet1:weblink_tab2:layoutPanel2:listbox1'); style="height: 72px; left: 144px; top: 192px; position: absolute; width: 288px; "/>
    </div>
    => Gives me good looking listbox but long filenames get truncated in display. No horizontal scroll bar.

  • Multi-select Listbox selections from jsp to servlet

    Hi,
    I have a jsp page with a multi-select listbox. I need to take the selections that the user makes and pass them back to a servlet, which then needs to format them for the where clause of my sql select query. I have worked with multi-select boxes before, but just moving the selections between listboxes never using the selections in a where clause of a sql query. Can someone give me some guidance on this subject or point me to some documentation? Thanks much!

    Don't muck about with fancy stuff in the HTML, just let the list box act like any other form component.
    Probably you aren't using the right methods to get the data from the request. Did you try getParameterValues("listboxname")? Did you try getParameterMap() to see what parameters were coming into your servlet?

  • For Multi Selection of Whare used list

    Dear Friends,
    I have Used T-code CS-15 for whare used list of material. if any other T-code for multi selection of materials for where used list.
    Please write.
    Thanks & Regards
    Ajit Sharma

    Hi Ajit,
    As mentioned in the previous posts, it is not adviced to have a multiple selection where-used, as the runtime is very long for this report.
    But if there is a specific need, you can build a Z report by using the FM -> CS_WHERE_USED_MAT
    But do ensure that your abaper puts in some restriction criteria. In the z report which i had done in one of the projects, i had put a restriction of 10 materials as the runtime was long.
    If helpful award points

  • Multi-Select (drop down list) data not saving upon save/email

    I have created a drop down list and modified it to allow multiple selection, i.e.
    form1.BusinessAreaTable[1].Row1[4].ERP::ready:form - (JavaScript, client)
    this.ui.choiceList.open= "multiSelect"; this.rawValue
    = "-1"
    However, when I go to save the form and/or email the list fields erase and the data / items I selected are gone.
    Please help, thanks.

    Okay, I have the form now.
    You are using script in the form Ready event to make a dropdown list mimic a listbox. This is totally unnecessary. I have changed the ERP to a multi-select listbox in the Object > Field palette and commented out the script.
    Here is the form: https://acrobat.com/#d=K*P4xKIA4kkqEHGTpgyvvw
    The form has not been Reader Enabled, so user with Reader will not be able to save the data inputted or submit by email in PDF format:

  • Can I create  a multi-selection list using a dynamic list of values?

    I'm reading section 19.7.3 from the dev guide - it explains how to create a selectOneListbox using a dynamic list of values. Is it possible to create a multi-select listbox from a dynamic list of values?
    What I would like to do - I have a read-only view object with a hard-coded query - I would like to display the results of the query in a dropdown list box, or dropdown list box with boolean checkboxes, to allow the user to select multiple items from the list. How can I accomplish this?
    thanks

    Hi JavaX,
    I don't know of any JSF components (at least not any ADF Faces components) that lets you do multiple selection in a drop-down. There is an af:selectManyListbox, but it does not render as a drop-down.

  • Different versions of multi-select controls

    Hello,
    Is there a way to substitute the multi-select control that OBIEE currently uses (a box with possible selections on the right, which the user selects by moving to the left)? Our users find that control very confusing, and would prefer something simpler such as checkboxes.
    I've worked with Business Objects, Cognos, and OBIEE, and I know it's not usual to have checkboxes, but even the multi-select listbox that BOBJ uses would be better than the OBIEE one. Has anyone tried anything like this?
    Thanks,
    Samori

    Cannot you insert those values into a temporary table and work within a subquery against that table ? That will make the code more secure, especially if the number of values is high.

  • OM: Multi-select order lines to apply hold

    We are using Standard Oracle Multi-Select order lines (Ctrl or Shift keys) to apply hold and would like to pop-up an alert when any of the selected lines is having an open delivery. Appreciate any suggestions to handle this requirement. Thanks !

    These are good links for the Apply Hold functionalities.
    What we are looking for is to alert users that any of the multi-selected lines is having an open delivery/shipper.
    Need to identify the internal Line_id multi-selected by users for validating if there is an open delivery/shipper.
    Appreciate any advise.

If you can force the failure again, is it possible to include the last part of the debug detailed log (set message level for user at 'debug detailed') in this thread?

  • Workaround for not being able to reference a multi-select field in a calculated field?

    Does anyone have a workaround for the fact that SP doesn't allow the use of a multi-select choice field to be used in a calculation in a calculated column?  I have a list that WAS a single choice in a Status field with three other calculated columns
    that were dependent upon that field.  Then I had to change the Status field to be to multi-select (checkboxes). Now of course my calculated columns don't work.  In addition, the end user can't fill them in either.
    I've got a Status field (multi-select), a Status Date field and Expiration Date field (calc).  The expiration date's calculation is shown below.   This worked great until I was asked
    to change the Status field to multi-select.<o:p></o:p>
    =IF(Status="NoI
    Review",DATE(YEAR([Status Date]),MONTH([Status Date]),DAY([Status
    Date])+21),"")<o:p></o:p>
    There are no mistakes; every result tells you something of value about what you are trying to accomplish.

    Hi run4it,
    Since SharePoint calculated column cannot reference the choice field with multiple-select value enabled, a workaround is to use workflow to copy the "Status" column value to another single line text column, then reference this single line text column in
    calculated column.

    However I'm getting the error above: "Lead selection not set for context node".
    Any suggestions?

    hi developement Themis,
    I think u didn't diclare "node" as context node. So declare it as a context node before using as a context node..as below
    DATA node  TYPE REF TO if_wd_context_node.
    or u can use  "lo_nd_child " as ur context node in ur program in place of "node"
    then I think this error will be removed.
    thanks,
    simadri
