Hide elements depending on other elements value

how can I hide elements (for example af:commandButton) when I change the value of another element (for example af:selectOneChoice)

<af:selectonechoice id="soc1" autoSubmit="true">
<af:commandButton id="cm1" partialTriggers="soc1" visible="#{bean.value}">in the valuechangevent of the selectonechoice.. set the value to false. so that the visible property will become false.. and the autosubmit will trigger the commandbutton to hide

  • Payroll: One Element Input Value dependent on Other Input Value

    Hi Guys
    Can we defined an input value in an element that is dependent on other input value. e.g. say when I am creating an entry to make accrual adjustments, converting 100 Annual Hours to 20 sick hours, I want users to enter 100 and 20 should be reflected automatically.
    Is this possible.

    I'm afraid you need a customization for this. I guess a forms personalization will not help you out. Or you enter it via an SIT (with the behavior stated), and you route that data to the element entry (via a user hook).

    Hi,
    Declare a flag value is false at starting when your condition occur make that value as true. In if condition mention if flag = true skip that line(out side the loop).
    Use flag logic.

  • How can I calculate the value of the cell, which depends on other rows?

    Hi, all!
    I have an application with table. In this table i have calculate some fields, that doesn't exists in data class and depends on other row values, e.g. current row number, or sum of previous rows. How can i calculate this values in TableView?
    The problem is that I have no information about the current row number in the cell value factory.
    Example:
    public class Transaction {
         public String getName();
         public BigInteger getAmount();
    } // There is no getter for "Balance"
    Result table should be something like this:
    Name
    Amount
    Balance
    transaction1
    300
    300
    transaction2
    200
    500
    transaction3
    500
    1000
    Also, after sorting by "Amount", "Balance" should be recalculated:
    Name
    Amount
    Balance
    transaction3
    500
    500
    transaction1
    300
    800
    transaction2
    200
    1000

    Strings can be converted to numbers by various parse methods. For instance Strings can be converted to double via Double.parseDouble(myString).
    That being said, it appears that your textfield will contain numbers and operators, and so these operators will need to be parsed too. I would advise you to search on the terms Java infix postfix.

  • Help with Show/Hide Elements please!

    I'm using the show/hide elements behavior for the first time and I'm not sure if it's working right. Am I supposed to be able to preview this feature, either in a browser or in Live View? It's not working in either, but I didn't know if the site had to actually be live for it to work or not.
    Also, my div is set to display:none; and I didn't know if that is correct, or if I should set a Z-index on all of them.
    Thank you!

    Am I supposed to be able to preview this feature, either in a browser or in Live View?
    Yes - it should work in both.
    Also, my div is set to display:none; and I didn't know if that is correct, or if I should set a Z-index on all of them.
    That could be the problem - show/hide toggles the visibility attribute between 'visible' and 'hidden'.  If the element is styled with display:none, even when it's visible it won't be displayed.  So, get rid of the display style, and just use the visibility one.  The default z-index is "1", so depending on your layout and the desired interaction with these elements, you may need to adjust your z-index as well.

  • Problem with ParseEscapedXML with " " in element value

    I'm having trouble with using getContentAsString, manipulating using a translate in a java embed, and then converting back using ParseEscapedXML. The trouble is occuring when there are "<" and ">" as element values. I'm not sure of a good way to convert the ">" to an escape value for only element values.
    I haven't been able to get the xsl:character-map function to work.
    Any tips would be greatly appreciated.

    HL7 is a flat file old style pipe and bar format for healthcare messaging. It has a section that lists the delimeters, which usually looks something like:
    MSH|^~\&|PMS|ASF|||200704200000||ADT^A04|1177045234.756.19114|P|2.4|||AL|AL
    Where the "&" is designated at the subcomponent separator. When Oracle's B2B tool parses the message and sticks it into an XML format it would break up the fields incorrectly if I had the customer put & lt ; in the flat file. I'm also trying to build a solution that is able to deal with this kind of issue without effecting the source feed.

  • Show/hide elements in DW CS3

    I've just posted this question and got a reply from John
    Waller, thanks John, but what I mean is that I don't want to use
    layers, this has to do with the positioning in a table. I want to
    add images to a table which is in a layer so I can put margin-left
    and margin-right for the layer to "auto" so the whole table
    (including images) will always be centered. If I add layers to the
    table and add images to the layers (to get the mouse-over effect)
    the layers will not move with the table to the center of the page,
    I hope you guys know what I mean.
    Anybody knows if it would be possible in DW CS3 to do so, see
    the original question underneath to get the picuture:
    Thanks again.
    Hi
    In DW8 I often used the possibility to put several layers on
    top of eachother with images in them, this way I could show/hide
    layers so the images would be visible when having a mouse-over
    action on a thumbnail for example.
    Now DW-CS3 gives the option show/hide elements, however, I
    can not simply put elements on top of eachother, which is what I
    want.
    Am I stuck on using DW8 and the show/hide layers option, or
    is there a way to put multiple images (elements) on top of
    eachother in DW-CS3?
    Thanks, have a nice day

    You don't need to use a 'layer' for that, and I assume that
    you mean a <div>
    not a layer, since the latter implies absolute positioning.
    > If I add layers to the table
    I sure hope you are referring to just div tags and not
    layers, because you
    would never want to put an absolutely positioned element
    directly into a
    table cell.
    > I hope you guys know what I mean.
    Yes, I'm afraid I do. This whole scheme is just wrong.
    It would be much better to use the SetText behavior to simply
    dynamically
    write the desired image link into a named container on the
    page, much like
    you can see being done here -

  • Container element value late update in ECC6

    Hi All,
    I have a problem with container element "RECEIVED" which has incomplete value. I'm using function SAP_WAPI_READ_CONTAINER (simple container) in my custom object ZBUS2081 method priceapproval. When 2nd person want to approve the workitem, the container value of element name "RECEIVED" only has previous approval person instead of table that has 2 line values (previous person who has already approved and 2nd person who want to approve this workitem).
    We have upgrade our SAP version from 4.7 into ECC6/ERP6, which in 4.7 version this container element returned table of 2 line values.
    Since the container element value has late to update the value, then it did not recognise as a final approval at the end of workflow step and raise an error for agent determination. If there is any related SAP note, please let me know.
    Thanks,
    Charlie

    Hello Charlie !
                Your RECEIVED container stores approver details.
                Please check the binding between method container to task container to workflow container.Imperfect binding could be a reason why approver details are not populated properly.It seems your container is multiline container.Make sure the method,task and workflow containers are multiline enabled. 
               Check at SWO1, whether the PRICEAPPROVAL method behaves as expected and if you are using rule for agent determination, you have to check the rule at PFAC as well as binding details.Also check at workflow log.
                Hope you have delegated ZBUS2081.

  • How to call pl/sql function from element values

    EBS 11.5.10.2
    XMLP 5.6.3
    Hello,
    I noticed that the output of the rdf-to-data template conversion process makes use of an undocumented feature of data templates, and I would like to get input from experts as to which situations this feature is usable.
    The closest thing I can find in the documentation is a sample in the user guide. There is a "General Ledger Journals Data Template Example" that has a <dataStructure> section that contains <element> nodes which are NOT children of a <group> node. I can't find any explanation of this in the user guide.
    I've noticed from converted templates that in these un-grouped elements you can make calls to PL/SQL functions in the "value" attribute, like this:
    <dataStructure>
      <group name="G_LINES" source="Q_MAIN">
        <element name="Line_Num"           value="Line_Num"/>
      </group>
      <element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
    </dataStructure>Has anyone had any success being able to call PL/SQL functions from grouped elements? Whenever I try, it doesn't seem to work.
    When I try something like this:
    <dataStructure>
      <group name="G_LINES" source="Q_MAIN">
        <element name="Line_Num"           value="Line_Num"/>
        <element name="some_calculation"   value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
        <element name="some_calculation_b" value="XX_CUSTOMPROCS.SOME_FUNCTION_B(:Line_Num)"/>
      </group>
      <element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
    </dataStructure>The <SOME_CALCULATION/> and <SOME_CALCULATION_B/> nodes come out empty in the output data xml file, but <C_CALCULATED_VALUE> would have a value as desired.

    ah - perfect. That makes sense. Thank you for the response!
    But what about when we need to pass parameters to those functions whos values are the results of aggregate element values?
    This happens a lot in the converted data templates, where pl/sql package functions are meant to replace formula columns from the original Oracle Report. Take this example from the conversion of ARXAGMW.rdf (Aging Report, 7 Buckets):
    (note the function call in the value of "Set_Percent_Inv_Inv" is using aggregate results from subgroups)
      <group name="G_INV_INV" dataType="varchar2" source="Q_Invoice">
        <element name="Total_Inv_Inv_Amt" function="sum" dataType="number" value="G_Invoice.C_Amt_Due_Rem_Inv"/>
        <element name="Total_Inv_Inv_B0" function="sum" dataType="number" value="G_Invoice.C_Inv_B0"/>
        <element name="Total_Inv_Inv_B1" function="sum" dataType="number" value="G_Invoice.C_Inv_B1"/>
        <element name="Total_Inv_Inv_B2" function="sum" dataType="number" value="G_Invoice.C_Inv_B2"/>
        <element name="Total_Inv_Inv_B3" function="sum" dataType="number" value="G_Invoice.C_Inv_B3"/>
        <element name="Total_Inv_Inv_B4" function="sum" dataType="number" value="G_Invoice.C_Inv_B4"/>
        <element name="Total_Inv_Inv_B5" function="sum" dataType="number" value="G_Invoice.C_Inv_B5"/>
        <element name="Total_Inv_Inv_B6" function="sum" dataType="number" value="G_Invoice.C_Inv_B6"/>
        <element name="Set_Percent_Inv_Inv"  dataType="number"  value="XX_CUSTOMPROCS.XXC_ARXAGMW.set_percent_inv_invformula(:Total_Inv_Inv_Amt, :Total_Inv_Inv_B0, :Total_Inv_Inv_B1, :Total_Inv_Inv_B2, :Total_Inv_Inv_B3, :Total_Inv_Inv_B4, :Total_Inv_Inv_B5, :Total_Inv_Inv_B6)"/>
        <element name="Sum_Percent_B0_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B0_Inv_p"/>
        <element name="Sum_Percent_B1_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B1_Inv_p"/>
        <element name="Sum_Percent_B2_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B2_Inv_p"/>
        <element name="Sum_Percent_B3_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B3_Inv_p"/>
        <element name="Sum_Percent_B4_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B4_Inv_p"/>
        <element name="Sum_Percent_B5_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B5_Inv_p"/>
        <element name="Sum_Percent_B6_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B6_Inv_p"/>
        <group name="G_Cust_Inv" dataType="varchar2" source="Q_Invoice">
          <group name="G_Site_Inv" dataType="varchar2" source="Q_Invoice">
            <group name="G_1" dataType="varchar2" source="Q_Invoice">
              <group name="G_Invoice" dataType="varchar2" source="Q_Invoice">
                <element name="C_Amt_Due_Rem_Inv" dataType="number" value="C_Amt_Due_Rem_Inv"/>
                <element name="C_Inv_B0" dataType="number" value="C_Inv_B0"/>
                <element name="C_Inv_B1" dataType="number" value="C_Inv_B1"/>
                <element name="C_Inv_B2" dataType="number" value="C_Inv_B2"/>
                <element name="C_Inv_B3" dataType="number" value="C_Inv_B3"/>
                <element name="C_Inv_B4" dataType="number" value="C_Inv_B4"/>
                <element name="C_Inv_B5" dataType="number" value="C_Inv_B5"/>
                <element name="C_Inv_B6" dataType="number" value="C_Inv_B6"/>
              </group>
            </group>
          </group>
        </group>
      </group>
      ...All of these groups and sub-groups are based on one single query, so I am not sure how I would move the function call into the query without changing the results of the function.
    In the example above, elements Sum_Percent_B0_Inv through Sum_Percent_B6_Inv grab the results of the calculation done in set_percent_inv_invformula. Here is the essence of that function:
      sum_percent_b0_inv := ROUND ((total_inv_inv_b0 / total_inv_inv_amt) * 100, 2);
      sum_percent_b1_inv := ROUND ((total_inv_inv_b1 / total_inv_inv_amt) * 100, 2);
      sum_percent_b2_inv := ROUND ((total_inv_inv_b2 / total_inv_inv_amt) * 100, 2);
      sum_percent_b3_inv := ROUND ((total_inv_inv_b3 / total_inv_inv_amt) * 100, 2);
      sum_percent_b4_inv := ROUND ((total_inv_inv_b4 / total_inv_inv_amt) * 100, 2);
      sum_percent_b5_inv := ROUND ((total_inv_inv_b5 / total_inv_inv_amt) * 100, 2);
      sum_percent_b6_inv := ROUND ((total_inv_inv_b6 / total_inv_inv_amt) * 100, 2);The only solution I can think of is to have separate queries, one for each subgroup, that do the "sum" in sql; but that seems terribly inefficient.

  • Directing workflow transition based on form element value

    Question 1
    =======
    How can workflow change values in a form element?
    Example: We have an expense aproval form.
    If the form transits from state ManagerA to state Reject, I want the form element Rejected by: to be automaticaly set to value ManageA.
    How ho achieve this?
    Question 2:
    ========
    How can a workflow read a form element and based on the element value automatically transit to other state?
    Example: An expense aproval form is in state ManagerA.
    If a user set the form element Rejected by manually to the value ManagerA, I want the form to be automatically transited from state ManagerA to state Rejected.
    How ho achieve this?

    Dangross, thanks for the reply. Yeah, that Transition on Entry Data Value will do the job.

  • EJB 3: Dynamic Element Values

    Hi all,
    I'm fairly new to EJB3 and I'm wondering whether it is possible to dynamically assign annotation element values like this:
    @Entity
    @Table(name=myClass.getTableName())
    public class Employee {
    }If not, what else can I do to use the same entity class and respective service class for different tables, which all have the same fields?
    Thanks in advance.
    Stephan

    Hi,
    You should be able to achieve what you're after extending the Employee entity and override @Table in every subclass. It should work. (I'd also be looking for something helpful in persistence.xml as that's where mapping and other configurations are - maybe there's a tag for mapping a class to a table?)
