SUBFORMS
A method is provided for displaying subforms in a perspective having areas and portlets. An entity represented by a portlet is configured using a form within the portlet. Sub-entities may require configuration as part of configuring the first entity. When a user configures a sub-entity, a subform is opened presenting means of configuring the sub-entity. The subform overlays most of the parent form, making the parent form inaccessible until configuration of the sub-entity is either accepted or cancelled. Using subforms, it is apparent to a user that configuration of the first entity is not complete until all related sub-entities have also been configured. Use of subforms within a portlet also allows other information necessary for configuration of the entity or sub-entities to be viewed by the user.
1 . A method of displaying a graphical user interface, comprising:
displaying one perspective;
within the perspective, displaying at least one area;
within each area, displaying at least one portlet tab, each such portlet tab being associated with a corresponding portlet;
within each area, displaying the portlet associated with a selected one of the at least one portlet tab within the area;
within one of the portlets which is displayed, displaying a form representing an entity to be configured, the form containing a first body containing a first list of at least one sub-entity to be configured before configuration of the entity is complete; and
when an entry in the first list is selected, displaying a first subform representing required configuration information for the corresponding sub-entity such that the first subform overlays the first body.
2 . The method of claim 1 wherein the first subform includes an accept button, and wherein the method further comprises:
upon selection of the accept button, if all required configuration information for the corresponding sub-entity is present closing the first subform and applying the configuration information for the sub-entity to the entity; and
upon selection of the accept button, if all configuration information for the corresponding sub-entity is not present displaying an error message.
3 . The method of claim 2 wherein the first subform includes a cancel button, and wherein the method further comprises closing the first subform without applying the configuration information for the sub-entity to the entity upon selection of the cancel button.
4 . The method of claim 1 wherein the first subform has a second body containing a second list of at least one further sub-entity to be configured before configuration of the sub-entity corresponding to the first subform is considered complete, and wherein the method further comprises displaying a second subform representing required configuration information for the corresponding further sub-entity such that the second subform overlays the second body when an entry in the second list is selected.
5 . The method claim 4 wherein the second subform has a third body, and wherein all bodies contain widgets used for entering or selecting information for configuration of the entity or sub-entity corresponding to the form or subform to which the body belongs.
6 . The method of claim 1 wherein the first list includes an add button, and wherein a form portlet is opened for entering configuration information of a new sub-entity upon selection of the add button.
