title: GWT RequestFactory and multiple requests
body: <p>Is there a way to use RequestFactory to create two entities in a single request?  I tried:</p>
  
  <pre><code>    EmployeeRequest request = requestFactory.employeeRequest();
      EmployeeProxy newEmployee = request.create(EmployeeProxy.class);
      newEmployee.setName("Joe!");
  
      Request&lt;Void&gt; createReq = request.persist().using(newEmployee);
      createReq.fire();
  
      EmployeeProxy newEmployee2 = request.create(EmployeeProxy.class);
      newEmployee2.setName("Sam!");
  
      Request&lt;Void&gt; createReq2 = request.persist().using(newEmployee2);
      createReq2.fire();
  </code></pre>
  
  <p>But I get an error that a request is already in progress.  When I made two separate EmployeeRequests:</p>
  
  <pre><code>    EmployeeRequest request = requestFactory.employeeRequest();
      EmployeeProxy newEmployee = request.create(EmployeeProxy.class);
      newEmployee.setName("Joe!");
  
      Request&lt;Void&gt; createReq = request.persist().using(newEmployee);
      createReq.fire();
  
      EmployeeRequest request2 = requestFactory.employeeRequest();
      EmployeeProxy newEmployee2 = request2.create(EmployeeProxy.class);
      newEmployee2.setName("Sam!");
  
      Request&lt;Void&gt; createReq2 = request2.persist().using(newEmployee2);
      createReq2.fire();
  </code></pre>
  
  <p>Then two separate requests are made from the browser.  I'm hoping that something in the RequestFactory can merge multiple requests - I have to create hundreds of entities at a time, and I don't want to make hundreds of requests!</p>
