Using HashMap in EL expression to set component properties in Oracle ADF

Basic requirement while using EL on pages in ADF, we use bean variables, binding attributes, iterators in expression to check conditions , to set properties for components as Enable-Disable, Visible, inline style etc.
in the same way we can use collections (Array, HashMap) in expression, i know it is pretty simple but have seen many thread in OTN asking how to use HashMap in expression

So here i am taking a very simple example



I have 5 input text on page and i have to enable-disable some fields based on it's id value, there is two buttons on page


as you can see on click of first button , input field 1,3 and 5 should be disabled and on click of second button af:inputText 2 and 4 should be disabled
so for this purpose i have used a HashMap in managed bean


    private HashMap fieldVal = new HashMap();

    public void setFieldVal(HashMap fieldVal) {
        this.fieldVal = fieldVal;
    }

    public HashMap getFieldVal() {
        return fieldVal;
    }

values in HashMap are populated using id value of inputTexts on page as key, this id will be passed as parameter in HashMap in expression
see how expression used in disabled property of inputText-


in same way expression for all inputText is set


<af:panelFormLayout id="pfl1" partialTriggers="b1 b2">
                    <af:inputText label="Label 1" id="it1" disabled="#{EnableDisableBean.fieldVal['it1']}"/>
                    <af:inputText label="Label 2" id="it2"
                                  disabled="#{requestScope.EnableDisableBean.fieldVal['it2']}"/>
                    <af:inputText label="Label 3" id="it3"
                                  disabled="#{requestScope.EnableDisableBean.fieldVal['it3']}"/>
                    <af:inputText label="Label 4" id="it4"
                                  disabled="#{requestScope.EnableDisableBean.fieldVal['it4']}"/>
                    <af:inputText label="Label 5" id="it5" autoSubmit="true"
                                  disabled="#{requestScope.EnableDisableBean.fieldVal['it5']}"/>
                </af:panelFormLayout>

now see code on buttons, simply setting values against key


    /**Method to disable inputText (1,3,5) on basis of id value
     * @param actionEvent
     */
    public void disable135Action(ActionEvent actionEvent) {
        fieldVal.put("it1", true);
        fieldVal.put("it2", false);
        fieldVal.put("it3", true);
        fieldVal.put("it4", false);
        fieldVal.put("it5", true);

    }

    /**Method to disable inputText (2,4) on basis of id value
     * @param actionEvent
     */
    public void disable24Action(ActionEvent actionEvent) {
        fieldVal.put("it1", false);
        fieldVal.put("it2", true);
        fieldVal.put("it3", false);
        fieldVal.put("it4", true);
        fieldVal.put("it5", false);
    }

Run Application and see what is on page
On Click of First Button

On Click of Second Button

Thanks
Happy learning :)

'filterFeatures' in ADF table column, caseInsensitive search in af:table filter

Quite small but useful trick-

In ADF table column when we apply search using filter it matches case (A-Z,a-z), means by default search is case sensitive, to change it you can change a property in column.



When you select a column and go to propertyInspector ,change 'filterFeatures' to 'caseInsensitive'
and It will search data in table without matching case

filterFeature property of table column to handle case sensitive search

Add Serial No. in Table in ADF, Auto Increment column in ADF table

ADF provides easy way to add a autoincrement column in table to make Serial No. or Sequence Column for table ,thats value autoincrements with no.of rows in table .
You have to follow these steps to do this.

  • Go to tabel properties (property Inspector) and set VarStatus to vs

set varStatus of af:table to vs
  •  Now add a column in table and drop an output text inside this new added column
Add new column to af:table to show serial number for each row
  • Select output text and Go to its property inspector and set value to #{vs.index+1} as it is selected in Expression Builder by going through- 
ExpressionBuilder----->JspObjects--->VS---->index




using varStatus we can access various built in function like index,count etc
  • You have done now run your page and you can see a serial no. column
af:table with serial number column
