Default value in the object MessageLovInput - with results mapped to fields MessageStyledText

Have a personalized page of the OPS with a simple LOV entry on this subject (MessageLovInput) for an account number that works very well.   User has entered an account number, the LOV works as it should and when the value is chosen I lovMappings that map a couple of fields result view-only MessageStyledText boxes indicating the name and address that was chosen.  Result - key user Acct # and the name and address appears automatically for the user for reference purposes.

However, I have an entry point to the screen where I would like to pass a parameter to the account number and have it auto select the LOV for me so that the only 2 display fields are visible.  In my controller page, I put the default account number (accountBean.setValue(pageContext,"12345") and it works EXCEPT that it never fill the results in the only fields of 2 display for the customer does not have the reference except with force, they choose the LOV and select the address.)

Is it possible to make the LOV "auto-run" at the entrance to the page so if there is an input value it will even act as if user keyed it?  I tried several variations of things of guide to Dev and Google for several hours and must be missing something.

Here's the Basic code that I have in place (cut down to simplicity)

PageCO-> ProcessRequest method:

String acctNumber = pageContext.getParameter ("InputAccountNumber");

If (acctNumber! = null)

{

Lov OAMessageLovInputBean = webBean.findChildRecursive ("AccountNumber");

lov.setValue (pageContext, acctNumber);

}

With just the code above, when the screen lorsque l' ecran commence begins has the InputAccountNumber appropriate in the account number field and correctly displayed.  The other fields only 2 screen remain blank well.  If I make a form submission (PageCO-> ProcessFormRequest), it correctly handles the LOV selection as well.

I tried to add the code to the stream to instantiate the LOV VO with the appropriate value and it works - selects the LOV properly and has a vo.getRowCount (1) because I expect.  But it's as if she doesn't have the lovMappings to the map screen.

Any suggestions?

Objects involved are:

MessageLovInput (with the region associated with listOfValues, tables and lovMappings, including mappings in Nom_tiers areas and address MessageStyledText)

LovVO-> query VO Sql Simple that is the query for the LOV (i.e. not based on an EO)

LovAM-> separate AM which houses the LovVO and is listed on the MessageLovInput

LovCO-> separate CO which house the PR and PFR for MessageLovInput field

PageCO-> controller for the page-> code LOV is the room above that sets the value.

PageAM-> AM for the page-> have you tried including the LovVO in its data model and it set aside.  Have you tried including a reference to the LovAM and removing it - same results

Got this working.  As aJohny said, I essentially had to manually set the other fields in the PR.  Had to do it in the PR of the PageCO since the LovCO is not called until the user interacts with the specific field of the MessageLovInput.

For reference, here's a rough description of what I had to do.

PageCO-> controller of main page in the ProcessRequest method:

(1) pick up the parameter and done a setValue on the MessageLovInput to the main field of LOV visible by the user.

(2) calls LovAM to initialize the specific LOV with the input parameter (see section LovAM below)

(3) calls LovAM to return the LovVO

(4) Gets the first line of the LovVO and fills the fields of the MessageStyledText (if there is only 1 line returned.  If 0 or 2 + it doesn't fill the dependent fields)

LovAM-AM for the LOV-> a > code to initialize the LovVO as follows

(1) Gets the LovVO

(2) setWhereClause (null) and setWhereClauseParams (null)

(3) setWhereClause to include the input parameter

(4) executeQuery

(5) If no input parameter then it gets just the LovVO and setWhereClause (null) (null) /setWhereClauseParams

LovCO-> controller of the LOV

(1) in PR-> call LovAM to initialize the VO with an empty/null input parameter.  This allows user to key in a new account number in the entry field Lov and it works.  In the contrary case, it always binds in the account number which is entered into the page as a parameter.

This method seems to work after a series of tests.  Seems like overkill for the lovMapping themselves and the feature base LOV all done automatically.  I expect to be able to do something to force the instantiate LOV and do its normal operations.  But I could never get this to work in the PageCO in the ProcessRequest method.

Thank you

    I was wondering if I saved a layer somewhere and set it as a default value.

    If you group the layers, you will be left with a single layer, thus spreading your concern.

    2. Reset the default preferences.

  • Can set the default value in the field with the rule

    I have a rule to set the xWebStartDate to dateCurrent(), but it does not work. I disabled all other rules, so there is no conflict. This rule is only to try to fix the date of xWebStart, nothing else.
    'Use the activation of rule condition' is checked. I selected 'Action of use' and 'check in Selected. I have added the xWebStartDate field and I have a default custom
    < $dprDefaultValue dateCurrent () = $ >
    Thus, it is for content that already exists and someone is to check in a new revision.
    I know that my rule works, because I added the dDocAuthor field and set it to "infOnly" and that works. This problem occurs if the action is updated also. But for check-ins again, I put the xWebStartDate to dateCurrent successfully.

    Update: it's existing content, which already has a xWebStartDate. The rule must replace the existing value.

    Edited by: ironarm February 1, 2013 17:58

    In your case, you cannot use default value for the new revisions, because your content is already a value for the metadata field.

    Alternative:
    (1) change your rule
    (2) on the general tab, check "Use activation Condition rule" and click Edit
    (3) in 'Edit Activation Condition' window, click on the tab "side effects".
    (4) add the following...

    <$if isCheckin $> [[%or you can also use (IdcService and IdcService like "CHECKIN_SEL_FORM")%]]
        <$xWebStartDate=dateCurrent()$>
    <$endif$>
    
  • Block initialization parameter default value of the session variable used in default prompt as "(toutes les valeurs de colonne)" "

    Hello

    I have a business requirement for a dashboard that we built location to get the users that belong to a certain geographic location to the default view of the dashboard with guests together in their geographic area.  He is just giving them a default view to enhance their experience when they connect each day.   Because of the way that we put the default value for the period of time they watch, with the HELP of SAUVÉ the CUSTOMIZATIONS IS NOT AN OPTION.

    I created the default values for the prompt called "area" in a block of initialization. This variable is called V_USER.

    My problem is that only about 80% of users have a value of 'Area' in the hierarchy of our employees.   I would like to someone else by default "(toutes les valeurs de colonne)". "  I was unable to understand how and where do.

    Some of the things I've tried:

    (1)Setting the default value in the initialization of an empty space block ("in SQL)
    (2)Setting the default value in the initialization "(toutes les valeurs de colonne) block '"
    (3)Setting the default value in the initialization block 'null '.

    None of them have worked and the result is that the user who does not have an area ends with a load of zombie dashboard, and while the guest gave rise to fashion "- select value -", the user must press "Apply" again to get the dashboard to display the data.

    The text which lies behind the encircled area in green below correctly becomes the value of the variable to V_USER (it is empty as default and I don't have a box).

    For @{biServer.variables ['NQ_SESSION.]} {[USERS ']} the default zone must be @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {}

    In the red circles below you can see that the guest actually becomes a value: *) nqgtu(* )


    The illustration below indicates the default value for a user without a box. the second quick block is not updated until you press on apply again...

    Thanks for your comments.  I was not able to make this work for my needs.  I have however to solve the problem by changing using a 'SQL result' for my default selection.  Then I created a query that returns rows NULL unless there is a correct answer:

    SELECT 'Service Delivery MOS '. "' Organizational hierarchy. "" Area ".

    "MOS DELIVERY."

    WHERE ("organisational hierarchy". ("" Area number "> 0) AND ("Service Delivery MOS". "Organizational hierarchy" "." " Zone' = ' @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {} ")"

    The "returns no line' I mentioned above resulted in all values being selected.

  • How to add the default value for the "Full - Text Search" box

    Hi all

    I am looking for the ability to add a default value for the "Full text search" box in the search form.

    Example:

    When the user accesses the search page it get default values for some fields (defined in the rule as default values) such as

    xField1 = txt1 and xFiel2 = txt2.

    and Furthermore we need full-text = Hello world.

    Is this possible?

    Another way that we use is to open the search by URL with coreContentOnly = 1 as a form:

    http:// < Server >/cs/idcplg? IdcService = GET_DOC_PAGE & to Action = GetTemplatePage & to Page = STANDARD_QUERY_PAGE & coreContentOnly = 1 & to xField1 = txt1 & to xFiel2 = txt2

    It is possible to add full-text criteria here? Somethig like: & text = Hello World

    Thank you

    Leon

    It is not possible in a very obvious way, not to mention that it is a rather strange request.  I can't really imagine a realistic use for this case.

    Anyway, without a messy customization, you should provide a default query with an FTX inside element text setting (i.e. "IdcService = GET_DOC_PAGE & Action = GetTemplatePage & Page = STANDARD_QUERY_PAGE & QueryText =Hello World" "")

    To do this in a profile in the secondary effects of the profile section, add the following:

    <$dpPromote("QueryText",>Hello everyone") $>.

    Hello

    I do not work with Apex that mutch, so this may be a simple question... but I still need help.
    I have a form, in this form, I have a question P19_ONTVANGER_ID, this is based on a LOV.
    This LOV is on a table that has a field of username with the value of APP_USER.
    The table looks like:
    ONTVANGER_ID this is the PK and is going to be the return value from the LOV.
    NAME is the display value for the LOV.
    USERID is the column APP_USER.

    What users would like to get is that if they create a new record, the default value for the P19_ONTVANGER_ID field is their own ONTVANGER_ID.
    But they must also be able to select another user.

    hope there is someone out there that can and will help me.

    Hello

    I think it's good if it fits your need.

    But why you have these fields in the form?
    created by: APPL_USER
    CREATION_DATE SYSDATE
    last_updated_by: APPL_USER
    last_update_date SYSDATE

    The user can enter the ones?
    I thought that those who are to audit and I would fill those drop with trigger in the database.
    So that you get the same "correct" values if you need to manipulate the data with example of sql client
