CAL and Tapestry 5, Part 2: Algebraic Types and Forms
In my previous post I described how to use a CAL function as part of the implementation of a Java class.
This post looks at interfacing CAL to Tapestry 5 using the ‘Java Bean’ conventions of getter and setter methods for the fields in an object.
Tapestry 5 provides a BeanEditForm component which simplifies providing CRUD operations for Beans. This is described in the second part of the Tapestry 5 tutorial.
By creating a Java class which provides a Bean with fields equivalent to the constructor parameters of a CAL algebraic data type we can use CAL to provide the data model for a web UI created with Tapestry. (more…)
