    SmartGWT and jBPM (or similar)

    Hi Isomorphic,

    we are currently planning a new SmartGWT application for our customers. In this we need the help of the jBPM Framework and would have to integrate it yourself. Have you already thought about an integration of jBPM (or similar)? Or can you recommend something?

    Regards,
    Timo

    In SmartGWT 3.0 we have started on a Workflow engine inspired by BPMN but designed to handle just the client-side aspects of Workflow (eg passing data back and forth between DataSources, forms, and programmatic steps).

    It's likely this could be connected to jBPM, and many of the things you might otherwise need to build yourself would count as Feature Sponsorship.

    If this is interesting, consider using the JumpStart program to have Isomorphic build an example integration between jBPM and the new client-side Workflow engine - use the contact form linked from the services page to get started, and provide a list of specific features / interactions you'd like demonstrated, as well as ideally some BPMN diagrams for the processes you want to execute.

      hi Isomorphic,

      that sounds very!! good, where can I find a small example (a code snippet would be enough for me already) of the "client-side aspects..." then I'll have to discuss the topic with my boss.

      with best regards
      timo

        If you grab a 3.x build from smartclient.com/builds you'll see a package com.smartgwt.client.util.Workflow with JavaDoc. This is just for reference about the intended functionality - keep in mind this is almost untested on the SmartGWT side although the underlying SmartClient classes have been pretty well tested.

          hi Isomorphic,

          thanks for the hint.

          My first little test case (I hope I have correctly understood the javadoc) does not work.

          Exception Message:
          $wnd.isc[scClassName] is undefined

          Has it been useful to deal with these new features, what is your opinion on it. (I know that it has not been tested properly.)

          Testcase:
          Code:
          package com.smartgwt.sample.client;

import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.core.KeyIdentifier;
import com.smartgwt.client.data.Record;
import com.smartgwt.client.util.KeyCallback;
import com.smartgwt.client.util.Page;
import com.smartgwt.client.util.SC;
import com.smartgwt.client.util.workflow.ScriptTask;

public class BuiltInDS implements EntryPoint {

    public void onModuleLoad() {
        KeyIdentifier debugKey = new KeyIdentifier();
        debugKey.setCtrlKey(true);
        debugKey.setKeyName("D");

        Page.registerKey(debugKey, new KeyCallback() {
            public void execute(String keyName) {
                SC.showConsole();
            }
        });
        
        
        ScriptTask firstTask = new ScriptTask("firstTask", "secondTask") {
            public Object execute(Object input, Record inputRecord) {
                return ((Double) input) + Math.random();
            };
        };
        firstTask.setInputField("startAmount");
        firstTask.setOutputField("endAmountFirstTask");

        ScriptTask secondTask = new ScriptTask("secondTask") {
            public Object execute(Object input, Record inputRecord) {
            	return ((Double) input) + Math.random();
            };
        };
        secondTask.setInputField("endAmountFirstTask");
        secondTask.setOutputField("endAmountSecondTask");

        com.smartgwt.client.util.workflow.Process process =
            new com.smartgwt.client.util.workflow.Process() {
            public void finished(Record state) {
            	
            	System.out.println("workflow finished!!!");
            	
            };
        };
        process.setElements(firstTask, secondTask);
        Record state = new Record();
        state.setAttribute("startAmount", 1.11);
        process.setState(state);
        process.start();

    }

 
}

          DevConsole:
          Code:
          onModuleLoad() threw an exception

            Again as we said:

            This is just for reference about the intended functionality
            .. we don't recommend trying to build anything yet, not until it's an announced feature. The particular problem you're having is because you haven't loaded ISC_Workflow.js, but you wouldn't know this because installation hasn't been covered in the docs yet.

              ok thanks, I'm waiting for the publication. Will there still be this year?

                Via the JumpStart program, you can get started with this now. When the starter application is delivered, it will use these APIs and your team will get training and/or a handoff session explaining everything.

                Other than that, we don't have an exact date, but we are thinking roughly Q4.
