How to set the disable,visible property in declarative components.

We have used one declarative component. It consists of 5 buttons (add,delete,save,delete,print). In all of our pages, this declarative component is used. We could bind methods and was able to use each pages seperately (by linking the methods in the backing bean)
But for implementing the DISABLE,VISIBLE properties, we have added the attributes for this and refered this to the corresponding disable and visible property of the button. In the page all these properties where reflected. But at the runtime these buttons are not coming.
Can anyone advise how can we set the disable,visible property in declarative components.

Hi vikram ,
i hvnt initialized the properties ,
in my declarative component i have one button say Save button and i want to config 2 properties Disable and Visible
i added two attributes ( java.lang.Boolean ) say disablr_btn ,*visible_btn* and mapped wth the Save button Properties Disabled and Visible using expressions
Now the button is invisible while running the page.
if i remove the mapping from properties Disable and visible , the button is visible
should i init the properties in faces config , i dnt knw hw to init the properties
pls advice

  • How to set the read only property for dynamic ALV column

    Hi All,
    I have built one dynamiv ALV and I have one name column inside that ALV for which I have to set read only property based on two column fields that exist in the same ALV,say IS_SP and IS_CORP of type boolean.
    If any one of the flag is 'X',i have to make that name column as display only and
    If both flag are not set,it should be displayed as ediatable column.
    I have written one method as INIT_ALV which gets called when ALV is loaded.
    Code is as  follows:
      lr_column_settings ?= wd_this->alv_all_roles.
      lt_columns = lr_column_settings->get_columns( ).
    LOOP AT lt_columns INTO ls_column.
    CASE ls_column-id.
       WHEN <NAMECOLUMN>. "name column which should be editable/display
    Create Input Field
            CREATE OBJECT lr_uie_input_field_ro
              EXPORTING
                value_fieldname = ls_column-id.
         ls_column-r_column->set_cell_editor( lr_uie_input_field_ro ).
        After this,I have to set the read only property based on IS_SP and IS_CORP values,
              CALL METHOD lr_uie_input_field_ro->set_read_only_fieldname
              EXPORTING
                *value = 'IS_SP' or 'IS_CORP'
    ENDLOOP.
    I dont want to use cell variants also.
    Help me to achieve this.
    Thanks and Regards,

    Divya - I have done it in the past following these documents. Please read it and try it it will work.
    Please read it in the following order since both are a continuation documents for the same purpose (it also contains how to change colors of row dynamically but I didnt do that part I just did the read_only part as your requirement)

  • Forms 10g : How to set the Database Item property for an item dynamically ?

    Hello all,
    I have a requirement where I need to set the database item property of an item to TRUE/FALSE
    dynamically at runtime based on certain conditions.
    Earlier, in forms 6i I've used,
    Set_Item_Property (<item_name>, DATABASE_ITEM, PROPERTY_TRUE);
    But in Forms 10g it doesn't recognize this Database_Item property and gives a compilation error.
    Have I overlooked something or has this property become obsolete in Forms 10g ?
    If obsoleted what is the replacement property ?
    Regards,
    Sam

    Some options:
    1. Create a database-view, including the "real" column in databases where it exists and a "dummy"-column in databases where it doesn't exist.
    If that's not possible,
    2. set database="No" for your item and
    -- create a POST-QUERY-trigger which reads the data for that column from the database, if the column exists, and
    -- create a ON-UPDATE-trigger which includes an
    UPDATE_RECORD;
    UPDATE THETABLE SET
      THECOLUMN=thevalue
    WHERE  ROWID=:THEBLOCK.ROWID;3. Base your block on either a select-from-clause, a ref-cursor or a procedure to adjust he query-part,, for saving use a procedure.

  • How to set the item property to restrict the user to not to copy from above

    Hi Guru's,
    I have a requirement like, There were two items on the form name email Id, Confirm email Id.
    I have to ristrict the user to not to copy from email Id item.. make him/her to enter the value into confirm email id item field manually.
    How to set the item property to restrict the user to not to copy from above item and paste it in this item.
    Please help.
    Thanks!!

    Just an opinion here, but that is about the dumbest requirement I have ever seen.
    I am always annoyed by web sites that ask me to enter my email twice. I ALWAYS copy the email address from the original entry and paste it into the second one.
    People enter their email addresses so often, it takes a real klutz to not get it right. And what makes you think that if they enter it twice, that they won't enter it wrong both times anyway???

  • How to set the source property of image control dynamically?

    Hi,
      I have different fxg files which I want to display in a list. For each row in the List, I define which fxg file to be displayed in my database.
    I need to know how to set the image1.source = (the fxg path) as a string from database?
    Is there any conversion needed in this case? If so, can you please help me how to do this?

    Hi,
      Thank you for your response. I am new to Adobe Flash Builder, Flex and action script. I don't get your answer straight away.
    What I basically need is, I need to set image1.source = strFXG. Right now, this does not show the image. I don't understand fxgObject.pathid.source => how to give this?
    Moreover, when I did google search, there is somethink like fxg converter which converts the fxg to a component. I thought this is a very simple problem on how to convert the fxg string to an object format. But now, it looks like it might be a big problem. Can anyone help me in this?
    import spark.components.Image;
                                  protected function view1_creationCompleteHandler(event:FlexEvent):void

  • SRM 4.0- How to set the default values for product type (01) only for SC

    The radio button “Service” should not be visible.
    Also for search help (e.g. search for internal products) where a search should only be possible for product type 01 (goods). The system should not display the product type and internally always search for goods only.
    How to set the default values for product type (01) only for SC
    We needs to use Search help BBPH_PRODUCT which having parameter PRODUCT_TYPE
    Here we can set defalut value 01 but it is not correct one since same search help is using several places.
    We need to limit the search help results only for SC.
    Kindly help out me ASAP.

    The easiest way to set defautl values is to edit the batch class.
    Goto the characteiristic and go to update values.
    In here you probably have something like 0 - 100 as a spec range.
    On the next line enter the default value within this range.  At the end of the line, click in the box in the column labelled "D".  This indicates the defautl value for the characteristic.
    If you need to you can do this in the material classification view as well.
    Just to be clear, these values will only show up in the batch record.  You can not have defautl values in resutls recording screens.

  • How to set the report path in a model plugin

    I am trying to figure out how to set the report path in a process model plug-in. I can seem to figure out how to get access to it. It seems like this would be a reasonable thing to do since the plug-ins are for results processing. Does anyone know how to do this? We typically use the Sequential process model but I am trying to keep my plug-in as independent of that as possible. 
    Thanks.
    Solved!
    Go to Solution.

    If I understand, you want your plug-in, when enabled, to alter the settings of any other instances of the NI report plug-in such that their reports share the same directory as your plug-in is configured to use.
    If so, your plug-in can access and modify the settings of all other plug-in instances. All instances are passed to all plug-in entries point in the plugins array sub-property of the ModelConfiguration parameter. You can iterate through this array. Any element of the array with a Base.SequenceFilename equal to "NI_ReportGenerator.seq" is an instance of the NI report plug-in. Its report options are stored in the element under PluginSpecific.Options.
    You can change the report options to what ever you want. Note that the ReportOptions model callback is called from the Initialize model-plugin entry point, so you might want to ensure that your changes are applied after that, so they aren't overwritten. To do that, you could make your changes in the the Initialize entry point of your plug-in, and ensure that your plugin runs last. To make it run last, you could set the FileGlobals.ModelPluginComponentDescription.Default.Base.RunOrder in your plug-in file to a value greater than 0, such as 1.0 (see TestStand Help>>Fundamentals>>Process Model Architecture>>Process Model Plug-in Architecture>>Structure of Plug-in Sequence Files>>Model Plug-in Entry Points>>Order of Entry Point Execution at Run Time).

  • How to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B

    Hi Friends,
    How to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B.
    External Trading Partner is sending the EDI 856 via AS2 URL to our Oracle B2B Server.
    In the inbound 856 agreement, we have checked the option of Funtional Ack and also Functiona Ack handled by B2B is yes.
    We have the outbound agreement which is sending that Functional ack 997 (auto generated by oracle b2b) and we have specified the Outbound AS2 channel of the Partner.
    997 doc is being sent to external partner using AS2 channel, but the filename is generating as '40101'.
    Please can you let me know how to set the AS2 fileName for outbound Functional Ack 997 auto generated by Oracle B2B.
    Appreciate your valuable answers!!
    Thanks,
    Amirineni

    Amirineni,
    AFAIK, there is no option to set the file name when the 997 is generated automatically by B2B.
    Alternatively, if this is a must requirement, you can generate the FA from backend and  send to B2B with MSG_TYPE =9. In this case, you can set the header with filename (How to set the actionname property in B2B 11g)

  • Sending image sequence job to compressor in command line : how to set the framerate?

    Hello,
    In Compressor, when you import a image sequence, it's possible to set the framerate and add an audio file before choosing a preset and lauching the encoding task.
    I want to dlo the same thing with command line. I know how to send a compressor job with command line, but no how to add theses settings.
    In the compressor command line help, we've got this :
    Job Info: Used when submitting individual source files. Following parameters are repeated to enter multiple job targets in a batch
              -jobpath <url> -- url to source file.
                                               -- In case of Image Sequence, URL should be a file URL pointing to directory with image sequence.
                                               -- Additional parameters may be specified to set frameRate (e.g. frameRate=29.97) and audio file (e.g. audio=/usr/me/myaudiofile.mov).
    So there are also framerate and audio parameters in command line but i've no idea how to write the command line with theses parameters
    Here is an example of command line for Compressor (by Apple) :

    You can see in the command sh running-config command
    show running-config : Displays the current access point operating configuration
    Use the guest-mode SSID configuration mode command to configure the radio interface (for the specified SSID) to support guest mode. Use the no form of the command to disable the guest mode.
    [no] guest-mode .
    Here is the guideline for usage
    The access point can have one guest-mode SSID or none at all. The guest-mode SSID is used in beacon frames and response frames to probe requests that specify the empty or wildcard SSID. If no guest-mode SSID exists, the beacon contains no SSID and probe requests with the wildcard SSID are ignored. Disabling the guest mode makes the networks slightly more secure. Enabling the guest mode helps clients that passively scan (do not transmit) associate with the access point. It also allows clients configured without a SSID to associate.
    Examples
    This example shows how to set the wireless LAN for the specified SSID into guest mode:
    AP(config-if-ssid)# guest-mode
    This example shows how to reset the guest-mode parameter to default values:
    AP(config-if-ssid)# no guest-mode

  • How to set the width of DataGridColumn dynamically?

    What I want to do is, load data from a text file and put into a DataGrid component, the fields of ech record in the text have fixed length, and are seperated by a space, like this:
    personal.txt
    50 Uvwxyz  Male    123456789
    60 Hijklmn  Male    67890123456789
    30 Abcdefg Male    123456789012345
    40 Opqrst   Female 987654321012345678
    the configuration file is column.xml:
    <dgcolumn>
         <personal>
              <len>20</len>
              <title>Name</title>
         </personal>
         <personal>
              <len>3</len>
              <title>Age</title>
         </personal>
         <personal>
              <len>6</len>
              <title>Sex</title>
         </personal>
         <personal>
              <len>20</len>
              <title>IdNumber</title>
         </personal>
    </dgcolumn>
    First I load the column.xml into an arrColumn, then read the personal.txt and seperate the record by the width( "len" in the xml file ), and put the seperated fields into another arrField, set the arrayFld as the dataProvider of a DataGrid, thus, the title can be showed as the headerText of the DataGrid and the data can be loaded correctly.
    private function handleComplete( event:Event ):void
         var arrField:Array = new Array();
         var arrFile:Array = loader.data.split(/\n/);
         for( var i:int = 0; i < arrColumn.length; i ++ )
              arrField[i] = convIcom( arrFile[i] );
         adgFile.dataProvider = arrField;
         trace( "The data has successfully loaded" );
    private function convIcom( strRecord:String ):Object
         var key:String = null;
         var dataField:String = null;
         var offset:int = 0;
         var obj:Object = new Object();
         if( strRecord.length > 0 )
              for( var i:int = 0; i < arrColumn.length; i ++ )
                   dataField = strRecord.substr( offset, arrColumn[i].len );
                   key = arrColumn[i].title;
                   obj[key] = dataField;
                   offset += arrColumn[i].len + 1;
         return obj;
    <mx:DataGrid x="10" y="100" width="400" id="dgFile" />
    The problem is, the width of the DataGridColumn is average, how to set the column width by the length of each field? I can calculate the rate of each field ( field / fields ), but I don't know how to change the property of the DataGridColumn.width.
    Thanks for helping.

    In the above post, I pasted an old version of personal.txt, so I paste it again:
    personal.txt
    Uvwxyz  50 Male   123456789
    Hijklmn 60 Male   67890123456789
    Opqrst  40 Female 987654321012345678
    Abcdefg 30 Male   123456789012345
    And I have another question, when the data is loaded into the DataGrid, the fields of each record are ordered in alphabetical order ( the "Age" column will appear firstly, then "IdNumber", "Name", "Sex" ), not as the order in column.xml, how to make it keep the sequence of the xml file?
    Thanks again.

    Good afternoon,
    This works: f?p=1:#MYPAGENUMBERCOLUMN#::Session:Request:Debug:Clearcache:itemname:itemvalue:printerfreindly
    It works very well. I have been struggling for a couple of hours trying to figure out how to calculate the page number I wanted to link to from a report column defined as a linked item. I ended up modifying my VIEW to include the page number for that particular type of data and use this technique to jump to the correct page.
    Thanks for posting this. Nothing else seems to work.

  • Sun ONE Studio 4 aka Forte: How to set the output path for classes ?

    Help !
    Beginner's question:
    Sun ONE Studio 4 aka Forte:
    How to set the output path for classes ?
    As default, the class files are created in the same directory as the
    sources.
    In opposite, both JBuilder and Together support that there is a tree
    with the sources and another tree with the classes.
    The first answer I got was "not possible with Forte, but just if you write your own "ANT Build script" !
    a) Please point me to a ready-to-use ANT script for this purpose, if such is available
    b) Is using ANT instead of the MAKE as comfortable ? Besides the separation of sourcecode and classes, I would like to keep everything else to be the same, i.e. I don�t want to edit the ANT file if I enlarge the project by directories or files.
    Tia
    Sincerely
    Rolf

    You can set S1S's options to place newly created .class files in a specific location.
    Identify the compiler that is being used - Open the S1S's Tools/Options window, expand Editing and select Java Sources. Note the Default Compiler value. (If it's one if the Ant options, you use Ant to specify this option, not S1S.)
    Open the S1S's Tools/Options window, expand Building/Compiler Types and select the appropriate compiler.
    The Properties tab of the compiler has the property Target, which sets the filesystem where the compiler output is directed. If you choose <not set>, the .class files are written to their source directory.
    When you set the Target, your change affects all classes that use this compiler.
    Very few options can't be set in S1S; the challenge is finding out where they're set!
