WSO2 Internship - V
In this series of posts, I provide some key points and Ideas that I report to my university during my internship. I arrange these posts as a set of reports, where each report provides the summary of tasks I have done during those four weeks of my training and the experience I gained during that period.
This post is the fifth post in the series of posts about my internship @WSO2.
I mainly focused on the last parts of my projects these four weeks, completing the search part and moving into the notification part. I have made the search part look like the one that existed in the Business Activity Manager’s Message Console. I also make it work efficiently for the dashboard level.

And I started doing that.
In the meantime, I also focused on the packaging artifacts as CApp. Then I started designing the dashboard first design dashboard to display the alerts that persisted in the event store. Then I focused on developing Interactive Map using the
Problem Encountered & Things I learnt
We can’t directly use the arbitrary attribute as it is commonly available as an arbitrary data map. The way to get specific arbitrary attribute is,
cast(map:get(ArbitraryMap,'relatedfield/key'), 'typeOfKey') as
typeOfKey can be string,long,int,double.
fieldName is used for ease of access.
cast(map:get(ArbitraryMap,'relatedfield/key'), 'typeOfKey') can be used to filter the input streams based on our requirement.
Dealing with jaggery controller with CApp
We can use jaggery controller at dashboard rather than deploying it at
Template manager use for complex event processing related concepts mainly, it is best practice for making the custom
