2.4. Creating ApprovalHelper Bean

Create the ApprovalHelper bean as described in the Creating Managed Beans section of the CUBA Studio User Guide.

Replace its content with the following code:

package com.company.bpmdemo.core;

import org.springframework.stereotype.Component;
import com.company.bpmdemo.entity.Contract;
import com.haulmont.cuba.core.Persistence;
import com.haulmont.cuba.core.Transaction;

import javax.inject.Inject;
import java.util.UUID;

public class ApprovalHelper {
    public static final String NAME = "demo_ApprovalHelper";

    private Persistence persistence;

    public void updateState(UUID entityId, String state) {
        try (Transaction tx = persistence.getTransaction()) {
            Contract contract = persistence.getEntityManager().find(Contract.class, entityId);
            if (contract != null) {

The updateState() method of the ApprovalHelper bean will be invoked from the contract approval process for setting a contract state.

Method parameters:

  • entityId – contract entity identifier;

  • state – contract state.
