The task log user interface brought together multiple component interactions between the views, models, and stores. We introduced the summary feature for grids and filtered records in both the Project and Task stores. Searching for the TaskLog records required us to parse the dates into an appropriate format for backend processing, while our basic model skeletons were enhanced with persistence and validation properties. We have once again explored interesting Ext JS 4 territory and worked with a variety of components.

In Chapter 12, 3T Administration Made Easy, we will develop the 3T Administration interface and introduce the Ext JS 4 tree component. The Ext.tree.Panel is a very versatile component that is perfectly suited to displaying the Company-Project-Task relationship.
