Abstract

The invention is directed to the capturing of user interface switch states. A method according to an embodiment of the invention includes: adding a state attribute to a UI switch control, the state attribute containing an expression; evaluating the expression relative to a UI binding of the UI switch control, if given, or a UI binding context node of the UI switch control, otherwise; and interpreting a result of the expression as a data layer node whose content is an ID reference to a case of UI controls that must be selected by the UI switch control.

Claims

1. A method for capturing user interface (UI) switch states, comprising:

adding a state attribute to a UI switch control, the state attribute containing an expression;

evaluating the expression relative to a UI binding of the UI switch control, if given, or a UI binding context node of the UI switch control, otherwise; and

interpreting a result of the expression as a data layer node whose content is an ID reference to a case of UI controls that must be selected by the UI switch control.

2. The method of claim 1, wherein, if the result of the expression is not a node or if the node content does not match any case ID, then a case selection for the UI switch control is made based on default or articulated properties of the cases.

3. The method of claim 1, wherein the UI switch control with state attribute is used within a UI repeat control that iterates a UI switch more than once, imparting a different UI context node to each UI switch control so generated.

4. The method of claim 1, wherein the UI switch control comprises an XForms switch element, and wherein the expression comprises an XPath expression.

5. The method of claim 1, further comprising:

selectively adding the state attribute to the UI switch control to preserve state.

6. The method of claim 1, further comprising:

performing a toggle action on the UI switch control with state attribute to change a switch case and update the data layer node indicated by the state attribute.
