• [ADF, JDev12.1.3] How to display a gif of loading during the loading of the af: table (through the ExecuteWithParams method call)?

  Hallo,

  in the fragment of my page, I created an af:table you drag an instance of VO for the data control; I also have a search button by dragging the operation ExecuteWithParams of the same instance of VO.

  I double clicked on the serach button to create the searchButton_action method in the bean calling the ExecuteWithParams operation after you have made a few operations.

  Next to the button, I put a table whose source is a gif of "load".

  I would like to make visible the gif while research is underway and make it invisible when the search is complete.
  

  
  

  In the beginning, I followed this approach.
  

  In the searchButton_action, I wrote the code to set the visible of the image property.

  But it did not work because the gif never appears. I also tried to set the property PartialTriggers of the image with the ID of the button table and search.
  

    public String searchButton_action() {
      RichActiveImage imgSearch = (RichActiveImage) FacesUtils.findComponent("ImgSearch");
      imgSearch.setVisible(true);
      AdfFacesContext.getCurrentInstance().addPartialTarget(imgSearch);
      // ...
      OperationBinding operationBinding = BindingsUtils.getBindings().getOperationBinding("MyVOInstanceExecuteWithParams");
      // ...
      imgSearch.setVisible(false);
      AdfFacesContext.getCurrentInstance().addPartialTarget(imgSearch);
      // ...
    }
  

  Then I tried with another approach which is to set the Visible property using the value off of the search button which is #{! links.} MyVOInstanceExecuteWithParams.enabled}

  But also, this approach has not worked.

  I also tried to set the property PartialTriggers of the image with the ID of the button table and search.

  What's not in my efforts? You could you kindly help me to solve the problem?

  Thank you

  Federico

  PS

  FacesUtils.findComponent is a method that retrieves the item passed as param. It works well since I used it several more times in my application.

  Your approach may not work add there is only a single thread of UI work. Your trigger reached the component when the execute with Péan has finished its work.

  For your use case there are a few solutions combining JavaScript and client-server events showing a window as long as the operation is running. Read https://blogs.oracle.com/groundside/entry/notification_during_long_running_transactions for all the info.

• [ADF, JDev12.1.3] (How to set values for the attributes 1) to create a file and 2) committing to the database?

  Hallo,

  in my tables and forms (created from VO istances) there are some areas for which, insert and update, I calculate and set the value programmatically when a record is created or updated.

  In some cases, I put the necessary values using the 'CreateWithParams' in the workflow diagram...

  

  In some other ones, I associate an action, a bean, a created button drag-and - drop operation 'CreateWithParams' of the istance VO...

    public String cwpButton_action() {
      BindingContainer bindings = getBindings();
      OperationBinding operationBinding = bindings.getOperationBinding("CreateWithParams");
      // here I calculate and set the needed params
      // ...
      Object result = operationBinding.execute();
      if (!operationBinding.getErrors().isEmpty()) {
        return null;
      }
      return null;
    }
  

  And is ok if I can calculate the values for the attributes before a new record is created.

  But the approach that I have used to define the attributes (for new and updated records) whose value should be caluclated after the user has filled in the fields, before committing to the database?

  Thank you

  Federico

  Federico,

  Let me first tell you that our code is activity masking errors (the cache instead of working on them).

  1. If (! operationBinding.getErrors () .isEmpty ()) {}
  2. Returns a null value.
  3. }
  4. Returns a null value.

  This means that you do not check the errors at all. You must at least print a log with the error message, you receive, if you get one!

  To solve your problem, you override the method prepareForDML() of the entity or entities in question. You can calculate and set the necessary attributes until they get engaged in the doDML(). Do not use doDML() because it is too late in the life cycle.

• [ADF, JDev12.1.3] How to set attributes for new records in detail your (by program) in a panel of master / detail tabbed?

  Hallo,

  in a fragment that I have a tabs including the 1st tab panel contains an af:form (created from a master VO) while the other tabs each contain an af:table (created from a VO detail).

  When the fragment is used in design mode , I need to set some attributes (hidden) for each VO.

  I guess I can begin to insert before the fragment, in the workflow, the operation "Create with Params" for the master VO.

  But who should I set the values for the fields the other VO's hidden when the user create new records?

  Some fields of VO can be set taking values directly from session and pageFlow scope while the value must be calculated for other fields.

  Thank you

  Federico

  

  Retail vo was create with Potsdam too. You can use what you can do to master VO. link the button to detail to a bean and calculated method to set the parameters before running the createWithParam.

  If you do not see sum label, I assume you are using an interactive report (IR).

• [ADF, JDev12.1.3] How to get the column headers, request of VO and VO bind vars used by an af:table?

  Hallo,

  I want to create a method that takes as a parameter the id of an af:table (used to display the search results) and returns:

  • the column headings of the af: table
  • Visible property (true/false) of the columns af:table
  • the actual query of the VO instance used to create the af: table
  • the values of real bind variables passed to the query of the instance of VO

  I would like to create a servlet which takes the parameters reruns the query and returns a report Excel/PDF file that contains exactly the same columns and same of the af records: table.

  I'm a little confused on who use the code to achieve this... you kindly help me?

  I did a similar qustion here Re: [ADF, JDev12.1.3] how to export an af:table to Excel in an ADF Essentials application? but then I guessed that it was preferable to create a new thread.

  Thank you

  Federico

  For this, you can use this type of code

  Context LocaleContext = _adfTableBinding.getLocaleContext ();

  for (attr AttributeDef: attributeDef) {}

  Label As String = attr.getUIHelper () .getLabel (context);

  _logger.info ("Attritbute name:" + attr.getName () + "column name:" + attr.getColumnName () + "Col4Query name:" + attr.getColumnNameForQuery () +)

  "Name:"+ label);

  }

  which produces this output

• [ADF, JDev12.1.3] How to resize and style default popup of the message of faces?

  Hallo,

  popups messages of faces that I take the floor in managed beans or auto-affichent by the application to show errors (e.g., https://dl.dropbox.com/s/hsje8m0meci2wai/FacesMessage.png?dl=0) do not adjust automatically based on the content.

  I would like to know how I can fix this problem and:

  • If and how I can style messages (content and containing);
  • If there is a simple way to display error messages online (e.g., https://dl.dropbox.com/s/rbw9i4h80mfvcxd/ErrMesInLine.png?dl=0);
  • If you can provide me with, if there are any, some nice links other ways to display messages in the ADF applications.

  Thank you

  Federico

  Well, for automatic resizing, you can use this workaround: https://agungor.wordpress.com/2014/05/14/handling-un-resizable-facesmessage-popup/

  Also, if I remember correctly, you can download the fix for this problem for Oracle Support(if you have support contract).

  Inline messages you must provide the id of the component when you create messages of faces.

  For global inline messages you need to af:messages component.

  As an alternative, you can use something like this: Awasthi (Jdev/ADF) Ashish Blog: better interface user-display the notification message of jQuery (for error, warning, info) to Oracle ADF

• [ADF, JDev12.1.3] How to set the value of an attribute of VO 'max (attribute) + 1' when creating a new record?

  Hallo,

  I have a VO that selects records from a table databace where FkId = < value >.

  For example: this is the database table...

  ID RowDetNumber OtherFields FkId

  1   3     1            ...

  2   3     2            ...

  3   3     3            ...

  4   3     4            ...

  5   4     1            ...         |
  

  6   4     2            ...         | -VO selects these records (where FkId = 4 for example)
  

  7   4     3            ...         |
  

  8   5     1            ...

  9   5     2            ...

  When a new record is created the field RowDetNumber must be calculated with the logic of the max (RowDetNumber) + 1.

  So for the example above, the calculated value should be 3 + 1 = 4.

  I would like to know how I can calculate the value and assign to the RowDetNumber attribute.

  I did some experiments using a Groovy expression as a default value for the field, but I got only errors.

  I'm a bit confused on how I can do so a few details / examples / tips are welcome

  In particular, a small example for every possible approach would be happy.

  Thank you

  Federico

  Federico, the solution mentioned in the block will work as it only generates unique numbers without guarantee that the generated numbers are without flaw. However, if you want to use max + 1 this normally means you want to have a sequence without gap. It is very very complicated in nature. It doesn't matter what application you're trying, there is almost always room for error, ending with duplicate numbers.

  The trigger also works as the DB supports triggers on MS SQL.

  If you don't need a number of gap-less for the attribute, you can use the groovy solution and just get a number of a sequence is is guaranteed unique and greater value, like the last number that you asked of the sequence. In this way, you can have the sorted records

  ID RowDetNumber OtherFields FkId

  1  3    1            ...

  2  3    7            ...

  3  3    9            ...

  4  3    10            ...

  5  4    3            ...        |
  

  6  4    5            ...        | -VO selects these records (where FkId = 4 for example)
  

  7  4    12            ...        |
  

  8  5    4            ...

  9  5    6            ...

  Double-click the validation button, to link Action property dialog will appear and then create a method of bean managed for the validation button.
  Then, add the following code to the method:

  public String saveButton_action() {}
  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding ("Commit");
  Object result = operationBinding.execute ();
  Note "!" operator has been removed from the default code.
  {if (OperationBinding.GetErrors (). IsEmpty())}
  FacesContext ctx = FacesContext.getCurrentInstance ();
  FacesMessage saveMsg is new FacesMessage ("saved successfully");.
  ctx.addMessage (null, saveMsg);
  }
  Returns a null value.
  }

  Then, restore the ActionListener value.

  I hope this helps.
