Problem with DynPage

Question

Hi, after successfully deployed a parfile of my DynPage application in the generated iView I've obtained the following error:
Eventhandler- "searchButtonClicked" or "onSearchButtonClicked" not found!.
and this is my code:
package .....;
import com.sapportals.htmlb.*;
import com.sapportals.htmlb.Form;
import com.sapportals.htmlb.TextView;
import com.sapportals.htmlb.enum.TextViewDesign;
import com.sapportals.htmlb.event.Event;
import com.sapportals.htmlb.page.DynPage;
import com.sapportals.htmlb.page.PageException;
import com.sapportals.portal.htmlb.page.PageProcessorComponent;
import com.sapportals.portal.prt.component.*;
import com.sapportals.portal.prt.runtime.PortalRuntime;
public class ReadUmePage extends PageProcessorComponent {
  public DynPage getPage() {
    return new ReadUmePageDynPage();
  public void init(IPortalComponentInitContext arg0) {
  public static class ReadUmePageDynPage extends DynPage {
     private String searchTerm = "";
     private String searchResults;
     private GridLayout grid;
Initialization code executed once per user.
    public void doInitialization() throws PageException {
Input handling code. In general called the first time with the second page request from the user.
    public void doProcessAfterInput() throws PageException {
Will always be called before output. So this is the method in which
the components will be placed and set.
    public void doProcessBeforeOutput() throws PageException {
          Form myForm = this.getForm();
          TextView myText = new TextView(); // set the TextView
          myText.setText("Search for: ");
          myText.setDesign(TextViewDesign.LABEL);
          InputField input = new InputField("SearchInput");
          input.setValue(searchTerm);
          Button searchButton = new Button("SearchButton");
          searchButton.setText("Search");
          searchButton.setOnClick("searchButtonClicked");
          grid = new GridLayout();
          grid.setCellPadding(5);
          Group searchGroup = new Group();
          searchGroup.addComponent(myText);
          searchGroup.addComponent(input);
          searchGroup.addComponent(searchButton);
          grid.addComponent(1, 1, searchGroup);
          //for testing purposes
          //grid.setDebugMode(true);
          insertSearchResults();
          Group group = new Group();
          group.setTitle("A DynPage using a portal service created from ReadUme WSDL");
          group.addComponent(grid);
          myForm.addComponent(group);
     private void insertSearchResults() {
     public void onSearchButtonClicked(Event e) throws PageException {
          InputField input = (InputField) this.getPage().getComponentByName("SearchInput");
          String searchTerm = input.getValueAsDataType().toString();
          IReadUmeService ReadUmeService = (IReadUmeService) PortalRuntime.getRuntimeResources().getService("meli.it.ReadUmeService.Alias");
          meli.it.ReadUmeGroup request = (ReadUmeGroup) null;
          meli.it.ReadUmeGroupResponse response = ReadUmeService.ReadUmeGroup(request);          
          String result = response.getResponse();
          System.out.println(result);
Where is the error ?
Thanks in advance

Hi Bello,
The problem is not in ur controller but it can be from you are view.
From where you are calling the Event is important.
Easy way to use is using HTMLB controls in JSP
In your JSP u can mention the eventhandler as follows:
<hbj:button
            id="SearchButtonId"
            text="SearchButton"
            width="80px"
            onClick="searchButtonClicked"
            disabled="false"
            design="STANDARD" >
   </hbj:button>
HTMLB is much more easy to build ur UI
Hope it gave u an idea ..
If u need more docs about HTMLB do tell me.
u can refer to <a href="https://help.sap.com/javadocs/NW04S/current/hb/index.html">HTMLB API</a> for further details
Thanks,
Swathi
