Overriding labels and Tooltip of input list of value programatically in ADF

Scenario: Suppose you have a LOV which has already labels and tootip for the attributes present in LOV.
Now you have some requirements like you have to reuse this LOV but the labels and tooltip must be different. This you can handle programatically also.

Suppose we have some labels and tooltip already for LOV as follows:


Now suppose you want the labels and tooltip for Dept. Id. should be "Department Number" and "For Dept. Name should be "Department Name".

In order to this you have to do following steps:

1. Create your bean class says LOVBean.
2. Override "launchPopupListener" in inputListOfValues as follows:

       <af:inputListOfValues id="departmentIdId"
                                popupTitle="Search and Select: #{bindings.DepartmentId.hints.label}"
                                value="#{bindings.DepartmentId.inputValue}"
                                label="#{bindings.DepartmentId.hints.label}"
                                model="#{bindings.DepartmentId.listOfValuesModel}"
                                required="#{bindings.DepartmentId.hints.mandatory}"
                                columns="#{bindings.DepartmentId.hints.displayWidth}"
                                shortDesc="#{bindings.DepartmentId.hints.tooltip}"
                                launchPopupListener="#{backingBeanScope.LOVBean.launchDeptLOV}">
            <f:validator binding="#{bindings.DepartmentId.validator}"/>
            <af:convertNumber groupingUsed="false"
                              pattern="#{bindings.DepartmentId.format}"/>
          </af:inputListOfValues>

3. Write the following code in "launchDeptLOV" method of bean.

    public void launchDeptLOV(LaunchPopupEvent launchPopupEvent) {
        BindingContext bctx = BindingContext.getCurrent();
              BindingContainer bindings = bctx.getCurrentBindingsEntry();
              JUCtrlListBinding lov = (JUCtrlListBinding)bindings.get("DepartmentId");
              ViewCriteriaManager vcm = lov.getListIterBinding().getViewObject().getViewCriteriaManager();
              vcm.removeViewCriteria(vcm.DFLT_VIEW_CRITERIA_NAME);
              ViewCriteria vc = new ViewCriteria(lov.getListIterBinding().getViewObject());
              vc.setName(vcm.DFLT_VIEW_CRITERIA_NAME);
              ViewObject vo = lov.getListIterBinding().getViewObject();
              AttributeDefImpl attrDef = (AttributeDefImpl)vo.findAttributeDef("DepartmentId");
              attrDef.setProperty(attrDef.ATTRIBUTE_LABEL, "Department Number");
              attrDef.setProperty(attrDef.ATTRIBUTE_TOOLTIP,"Department Number");
              AttributeDefImpl attrDef2 = (AttributeDefImpl)vo.findAttributeDef("DepartmentName");
              attrDef2.setProperty(attrDef2.ATTRIBUTE_LABEL,"Department Name");
              attrDef2.setProperty(attrDef2.ATTRIBUTE_TOOLTIP,"Department Name");
    }

Now when you run your page and open the LOV you can see that labels and tooltip for both the attributes got changed.

You can do it by the command line also by typing the following command. mkdir  angular2-example Now once the directory is created you need to create three files. 1. tsconfig.json 2. typings.json 3. package.json 1.  tsconfig.json This file is TypeScript compiler configuration file. It guides the compiler to generate JavaScript files after compilation. The content of this file will be as follows: {   "compilerOptions": {     "target": "es6",     "modu...

Now your panel collection has some facet with name "statusbar", "toolbar" etc. Right click on facet "toolbar" and select "insert after f : facet toolbar and then "Facet Secondary Toolbar" as shown below in image. Now on facet "statusbar" and "secondaryToolbar" put toolbar component from component pallet. Then put a output text inside each toolbar as follows:  <f:facet name="secondaryToolbar">             <af:toolbar id="t3" stretchId="s2">               <af:spacer width="10" height="10" id="s2...
