Abstract

The present invention enables a three-pane page flow editor optimized for viewing and editing a page flow. It provides a visual representation of nodes and the connections among them, enabling the ability to read and edit connections between nodes in a local area of the page flow without the overlaps between lines and crossovers once the page flow grows complex in real applications. In addition, a declarative validation rule editor is operable to create and manage a plurality of declarative validation rules of the page flow and their associated messages at design time which can be used by the page flow runtime to keep the user from entering and/or submitting bad or invalid data into the page flow. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Claims

1. A system to support declarative validation rule for page flow editing, comprising:

a page flow comprising of a plurality of nodes and links among the nodes,

wherein the page flow represents a set of Web application files used to implement a user interface;

a page flow editor operable to display and edit the page flow;

a control module operable to support displaying, navigating, and editing of the page view via the page flow editor; and

a declarative validation rule editor operable to create and manage a plurality of declarative validation rules of the page flow and their associated messages to keep a user from entering and/or submitting bad or invalid data into the page flow.

2. The system according to claim 1, wherein:

each of the Web application files is a Java file.

3. The system according to claim 1, wherein:

each of the plurality of nodes is one of;

an external page, a html file, a plain text file, another existing page flow, a control, a shared flow, and a message bundle.

4. The system according to claim 1, wherein:

the page flow editor is operable to support at least one of;

an overview of the page flow being edited; and

generating and displaying routes of links between nodes in the overview of the page flow.

5. The system according to claim 1, wherein:

one of the plurality of validation rules is inherited, which only to be viewed but not edited.

6. The system according to claim 1, wherein:

one of the plurality of validation rules is defined relative to a property and resides in one or more validation locales.

7. The system according to claim 6, wherein:

the property is inherited and overrides the validation rule.

8. The system according to claim 6, wherein:

the declarative validation rule editor is operable to duplicate and re-categorize the plurality of validation rules and/or the one or more validation locales by copying and moving nodes in the pane in a drag and drop fashion.

9. The system according to claim 1, wherein:

the declarative validation rule editor is launched from an action and/or a bean in the page flow.

10. The system according to claim 1, wherein:

the declarative validation rule editor is operable to display and edit the plurality of validation rules in a tree structure.

11. The system according to claim 1, wherein:

the declarative validation rule editor is operable to present one of the plurality of validation rules and/or its associated error message.

12. The system according to claim 1, wherein:

the declarative validation rule editor is operable to display and edit one or more argument of the plurality of validation rules.

13. The system according to claim 1, wherein:

the declarative validation rule editor is operable to save the plurality of validation rules as metadata that the page flow runtime can use and enforce.

14. A method to support declarative validation rule for page flow editing, comprising:

representing a page flow via a plurality of nodes and links among them,

wherein each of the plurality of nodes represents an action in the page flow that is used to implement a user interface;

displaying, navigating, and editing the page flow via a page flow editor; and

creating and managing a plurality of declarative validation rules of the page flow and their associated messages to keep a user from entering and/or submitting bad or invalid data into the page flow.

15. The method according to claim 14, further comprising:

supporting an overview of the page flow being edited.

16. The method according to claim 14, further comprising:

generating and displaying routes of links between nodes in the overview of the page flow.

17. The method according to claim 14, further comprising at least one of:

defining one of the plurality of validation rules relative to a property,

which resides in one or more validation locales;

overriding the validation rule if the property is inherited;

duplicating and re-categorizing the plurality of validation rules and/or the one or more validation locales by copying and moving nodes in the pane in a drag and drop fashion; and

presenting one of the plurality of validation rules and/or its associated error message.

18. The method according to claim 14, further comprising:

displaying and editing one or more of;

the plurality of validation rules in a tree structure; and

one or more argument of the plurality of validation rules.

19. A machine readable medium having instructions stored thereon that when executed cause a system to:

represent a page flow via a plurality of nodes and links among them,

wherein each of the plurality of nodes represents an action in the page flow that is used to implement a user interface;

display, navigate, and edit the page flow via a page flow editor; and

create and manage a plurality of declarative validation rules of the page flow and their associated messages to keep a user from entering and/or submitting bad or invalid data into the page flow.

20. A system to support declarative validation rule for page flow editing, comprising:

means for representing a page flow via a plurality of nodes and links among them, wherein each of the plurality of nodes represents an action in the page flow that is used to implement a user interface;

means for displaying, navigating, and editing the page flow via a page flow editor; and

means for creating and managing a plurality of declarative validation rules of the page flow and their associated messages to keep a user from entering and/or submitting bad or invalid data into the page flow.
