This blog is about applying filter selection across multiple applications from a mashup. This is essential in scenarios where we have apps that share common data fields.For example, HR system and project management systems may have different data and for some reason this need to be separate, we can merge them together in the mashup and apply filters together.
In this example, for simplicity, a copy of Helpdesk app, that is part of the example apps that comes along with
Qliksense desktop implementation, is created and a chart title is renamed for explanatory purpose.
You can download the working source code of this mashup.
One main objective of this approach is to NOT use any custom filters as that would require additional development and maintenance efforts. Also, if not implemented correctly it may lead to performance degrade.
Technically, one may encounter two scenarios where filter needs to be applied on more than one app.
Secnario 1: A single page that renders visualization from more than one app to the user
Scenario 2: Two separate modules (pages) exist and user goes from one module (page) to another and the context (filter selection) needs to be preserved between the modules. Or there is a need to preserve selection between two different sessions.
