Custom actions in KCenter

The following sample demonstrates how to create a new custom action in the KCenter.

Sample based on a JSP

Step 1 - Create a sample JSP file

Create the following sample JSP file and copy it to the webapps/openkm folder named test.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ page isErrorPage="true" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

<html>
<head>
  <script type="text/javascript" src="<%=request.getContextPath() %>/kcenter/api/common.js"></script>
  <script type="text/javascript" src="<%=request.getContextPath() %>/kcenter/api/modal.js"></script>
</head>
<body>
  <h1>Quick sample about how to create a custom action in the KCenter</h1>

  <p><b>UserId:</b> <%=request.getParameter("userId")%></p>
  <p><b>Uuid:</b> <%=request.getParameter("uuid")%></p>
  <p><b>Encrypted token:</b> <%=request.getParameter("token")%></p>

  <button onclick="_closeCustomFeatureModal()">Close popup</button>
</body>
</html>

Step 2 - Register the custom action

Create a new custom action with these values. More information at Custom actions.

Field	Value
Name	test
Label	Label test

Folder	true
Record	false
Mail	false
URL	../test.jsp Another option: http://localhost:8080/openkm/test.jsp
Action	popup-wizard
Location	node-toolbar
Width	50%
Height	50%
Show close	true

Step 3 - Enable the custom action in the profile

• Go to Administration > Profiles 
• Edit a profile and enable the custom action in the Misc tab.

Step 4 - Check the feature

    if (isLocked) {
      long tenantId = PrincipalUtils.getTenantId();
      String systemToken = DbSessionManager.getInstance().getSystemToken(tenantId);

      dbNodeModule.forceUnlock(systemToken, uuid);
    }
  } catch (Exception e) {
    error = StackTraceUtils.toString(e).replaceAll("\n","<br/>");
    e.printStackTrace();

      <% } else { %>
        <p class="text-success">The node has been unlocked</p>

Validation script	Available since version 8.1.15. The return statement must be a boolean value or a promise, like the example below. async function main() {   console.log(‘execute main’);   const kcenterApp = window.kcenterApp;   const currentNode = kcenterApp.$store.getters[‘browser/currentNode’];   const isValid = await hasGroup(currentNode.uuid);   console.log(’isValid: ’ + isValid);   return isValid; // Return is valid } async function hasGroup(uuid) {   const response = await kcenterApp.$ws.propertyGroup.getGroups(uuid);   console.log(response); // Groups of the node   const found = response.some(group => group.name === ‘okg:consulting’);   return found; } // Return the promise ( will be executed in the UI ) or a boolean value return main();

Step 2 - Enable the custom action in the profile

• Go to Administration > Profiles 
• Edit a profile and enable the custom action in the Misc tab.
