BPM: Increase the UX with Active Waiting

Hi,

I had some projects in the past where Oracle BPM has been involved and I have been asked many
times on how can we improve the experience of

Initiating an Asynchronous Process and redirecting Automatically to the first Human Task UI when available

The code of this post can be found in my GitHub
https://github.com/DanielMerchan/ActiveWaitingDemo

Architecture of the Active Waiting Demo

The following diagram describes the Architecture of the Demo.


  • 1. The ADF UI Application starts a Asynchronous BPM Process by calling the start asynhronous interface exposed by the BPM Process.
    • 1.a: The First Activity of the BPM Process registers in a CUSTOM database table the Process Info. This information is needed by useful administrative SOA API which is used to retrieve the Audit Trail and other statuses of a BPEL / BPM Process.

       
      • Note: The BPM Process has 3 Timer Activities to simulate processing before a Human Task is reached
    • 1.b: The Poller starts first trying to get the Process Instance Id by the custom id of our process. Once it is taken then 2 happens
  • 2: We use the Process Information to invoke the SOA API which can makes us to check the Audit Trail / Audit Image of a BPEL / BPM Process.

    • We poll the SOA API to refresh the status of the BPM Process being executed in Background. You can find the PollerEvent in the AssignedTasksBacking.java
    • Once the BPM Process has reached a Human Task. We can add the logic to redirect the user to its URL if the user is part of the Assignees of the Task. In addition, we also Auto-Claim the Task

OJET: Inter-Module communication in TypeScript Template

Image
In this post I bring another example on how to Communicate Modules using the Oracle JET - TypeScript Template based on the Oracle JET Cookbook: InterModule Communication From now and so on will create multiple examples using TypeScript for those who are not familiar with it and wants to turn the Cookbook examples into TypeScript :). The example ( ojet-typescript-list-detail ) can be found as usual in my GitHub repository: https://github.com/DanielMerchan/ojet-examples This example is a bit different compared to the Cookbook example where the modules are not running at the same time within a Module. This example is built as described in the following images: Customers module acts as the Wrapper Module. It coordinates when to load the list and detail modules. Customers module makes use also of signals npm module for communication between Customers-List, Customers-Detail. Explanation of the Example customers.js is the coordinator responsible module for: initiali

OJET: Build and Deploy in an Application Server

Image
There are some other sources where an Oracle JET Application is packaged and deployed as a WAR in Oracle WebLogic Application Server (Arda Eralp) https://blogs.oracle.com/ardaeralp/deploy-oracle-jet-application-to-weblogic-server (Andrejus Baranovski's) http://andrejusb.blogspot.com/2016/07/serving-oracle-jet-application-from.html They may look bit old or maybe because they call directly grunt tasks by using the grunt-cli . In this post I will update a bit these posts in Oracle JET 6.1.0 and the usage of ojet build (instead of calling the grunt tasks) for also building the corresponding WAR file. The example can be found in my GIT repository: https://github.com/DanielMerchan/ojet-examples Let's start... Install grunt-war module in your Oracle JET Application. npm install grunt-war --save-dev Create a war.js (or call it whatever you want) in /scripts/grunt/config folder under your souce files. This is a sample code inside of it, check https://www.npmjs.com/packag

OJET: Select All options using only Checkboxset

Image
This is an example on how to select all other options by using another oj-checkboxset. GitHub: ojet-checkbockset-select-all The idea is to keep track of the selection and make use of the on-value-changed as described in the following code. self.colorOptions = ko.observableArray([ { id: "blueopt", value: "blue", color: "Blue" }, { id: "greenopt", value: "green", color: "Green" }, { id: "redopt", value: "red", color: "Red" }, { id: "limeopt", value: "lime", color: "Lime" }, { id: "aquaopt", value: "aqua", color: "Aqua" }, ]); self.selectAll = ko.observableArray([]); self.currentColor = ko.observableArray(["red"]); self.selectAllOptionChanged = (event) => { const newSelection = event.detail.value; if (newSelection.indexOf('all')
