Passing parameter in XML Resource and Use it in Managed Bean, Using parameterised Resource Bundle in ADF

If we are developing an Fusion Web application and we are thinking about Multilingual application , then the best option i came to know is to use Resource Bundle properties of ADF . When we use resource bundle we have to use labels of Fields and Validation message or any kind of other custom message from a XML file as Resource.xml.
So first you should know that how to configure resource bundle in an ADF Application and there are plenty of posts about configuring Properties or List ResourceBundle.

In this post i will show you that how to pass parameter in XML or how to use Parametrized resource .

Suppose i  have a xml file for ResourceBundle reference Resource.xml--

1. <?xml version="1.0" encoding="windows-1252" ?>
2. <bundle>
3. <label>
4.     <key>MessageCheck</key>
5.     <value>Only %s %s %s %s %s allowed</value>
6.  </label>
7. </bundle>

and now i use it in managed bean to show a custom message and replace its parameters %s with any desired value then we code like this

1. //To get String from XML key, resolvElDC is a method to resolve expression language
2. String message = resolvElDC("#{bundle['MessageCheck']}").toString();
3. //here replace parameter(%s) in string message with your values
4. String saveMsg = message.format(message, ",", "/", "@", "_", "%");
5. //Show FacesMessage
6. FacesMessage msg = new FacesMessage(saveMsg);
7. msg.setSeverity(FacesMessage.SEVERITY_INFO);
8. FacesContext ctx = FacesContext.getCurrentInstance();
9. ctx.addMessage(null, msg);
12. // Code for resolvElDC method
14. public Object resolvElDC(String data) {
15.     FacesContext fc = FacesContext.getCurrentInstance();
16.     Application app = fc.getApplication();
17.     ExpressionFactory elFactory = app.getExpressionFactory();
18.     ELContext elContext = fc.getELContext();
19.     ValueExpression valueExp = elFactory.createValueExpression(elContext, data, Object.class);
20.     return valueExp.getValue(elContext);
21. }

Now run your code and see the updated message- Only %s %s %s %s%s allowed is now
 

Clear af:table Filter Value declaratively in ADF, Reset table filter

When we use table component with filter, and we have to manually clear the data that we search by filter.
but ADF provides functionality to clear filter data by one click on Filter icon.

When We drop table on page and it looks like this

Now we have to set atleast one column with RowHeader --true in propertyInspector of table Column.
It mean select table column and go to property Inspector and Set RowHeader to true

Now run the page, and search something using table filter

Now click on the clear icon that is appearing on head of column , for that we have set RowHeader to true

and your table filter get cleared when you click on that icon.

Cheers :) Happy Learning

Set on Current row after Rollback Execute or page refresh

Some times we edit a table in form and Save(Commit & Execute) or Cancel(Rollback & Execute)  and table refreshed to its first record means focus is now on first row of table.
And we need the same row again, then we search it and perform another operation, this is really disgusting behavior of table for Developer.

To set on previously selected row after execute we can use this code,
in this scenario we have to get current row key from its IteratorBinding and after Execute we can set it again to show that row as selected.

    /**
     * Generic Method to call operation binding
     **/
     public BindingContainer getBindings() {
      return BindingContext.getCurrent().getCurrentBindingsEntry();
     }


     BindingContainer bindings = getBindings();
     //Get Iterator of table
     DCIteratorBinding parentIter = (DCIteratorBinding)bindings.get("IteratorName");
     //Get current row key
     Key parentKey = parentIter.getCurrentRow().getKey();

     //You can add your operation code here, i have used simple Cancel operation 

     //with Rollback and Execute
     
     
     OperationBinding ob= bindings.getOperationBinding("Rollback");
     ob.execute();
     OperationBinding ob1= bindings.getOperationBinding("Execute");
     ob1.execute();
    
     //Set again row key as current row
     parentIter.setCurrentRowWithKey(parentKey.toStringFormat(true));
