Description copied from class: Controller

Called by child views and controllers to request a model reference. By default it delegates calls to the parent controller if one is found. Override this method to declare a model local to the controller. Always make sure to delegate the call to the superclass if the requested type is not one which is defined locally. For example:

Overrides:

requestModel in class Controller

public void setLastUpdated()

beforeShow

public void beforeShow(Callback<Boolean> onReadyCallback)

Description copied from class: LayoutController

Default implementation does nothing on before show. Override to do other things before THIS view is shown.

Specified by:

beforeShow in interface View

Overrides:

beforeShow in class LayoutController

See Also:

View.beforeShow(org.kuali.student.common.ui.client.mvc.Callback)

showView

public <V extends Enum<?>> void showView(V viewType,
                                         Callback<Boolean> onReadyCallback)

Description copied from class: Controller

Directs the controller to display the specified view. The parameter must be an enum value, based on an enum defined in the controller implementation. For example, a "Search" controller might have an enumeration of: public enum SearchViews { SIMPLE_SEARCH, ADVANCED_SEARCH, SEARCH_RESULTS } The implementing class must define a getView(V viewType) method that will cast the generic enum to the view specific enum.

Overrides:

showView in class MenuEditableSectionController

Type Parameters:

V - view enum type

Parameters:

viewType - enum value representing the view to show

onReadyCallback - the callback to invoke when the method has completed execution

showDefaultView

public void showDefaultView(Callback<Boolean> onReadyCallback)

Description copied from class: Controller

Shows the default view. Must be implemented by subclass, in order to define the default view.

Overrides:

showDefaultView in class LayoutController

setParentController

public void setParentController(Controller controller)

Description copied from class: Controller

Sets the controller's parent controller. In most cases, this can be omitted as the controller will be automatically detected via the DOM in cases where it is not specified. The only time that the controller needs to be manually set is in cases where the logical controller hierarchy differs from the physical DOM hierarchy. For example, if a nested controller is rendered in a PopupPanel, then the parent controller must be set manually using this method

Overrides:

setParentController in class Controller

Parameters:

controller - the parent controller

checkAuthorization

public void checkAuthorization(AuthorizationCallback authCallback)

Specified by:

checkAuthorization in interface RequiresAuthorization

setViewContext

public void setViewContext(ViewContext viewContext)

Description copied from class: Controller

Sets the view context. This is important for determining the permission for seeing views under this controllers scope, what the id and id type of the model the controller handles are defined here. Additional attributes that the controller and it's views need to know about are also defined in the viewContext.

Overrides:

setViewContext in class Controller

addPermissionAttributes

public void addPermissionAttributes(Map<String,String> attributes)

This method adds any permission attributes required for checking permissions

isAuthorizationRequired

public boolean isAuthorizationRequired()

Specified by:

isAuthorizationRequired in interface RequiresAuthorization

setAuthorizationRequired

public void setAuthorizationRequired(boolean required)

Specified by:

setAuthorizationRequired in interface RequiresAuthorization

setHeaderTitle

protected void setHeaderTitle()

getWfUtilities

public WorkflowUtilities getWfUtilities()

Specified by:

getWfUtilities in interface WorkflowEnhancedNavController

beforeViewChange

public void beforeViewChange(Enum<?> viewChangingTo,
                             Callback<Boolean> okToChange)

Description copied from class: LayoutController

This particular implementation of beforeViewChange checks to see if all its view contains a Controller and if it does checks with that controller to see if it is ok to change the view. OkToChange callback will be exec with true if the view is allowed to be changed at this time. This method can be overriden to provide additional functionality to stop a view from being changed when there is some additional processing that needs to occur in the ui before the view changes.

Overrides:

beforeViewChange in class LayoutController

See Also:

Controller.beforeViewChange(java.lang.Enum, org.kuali.student.common.ui.client.mvc.Callback)

getSaveButton

public KSButton getSaveButton()

getCancelButton

public KSButton getCancelButton(Enum<?> summaryView)

onHistoryEvent

public void onHistoryEvent(String historyStack)

Description copied from class: Controller

The onHistoryEvent implementation in controller reads the history stack it receives and determines if the next token/view to be processed is a controller, if it is, it hands off the rest of the history stack to that controller after showing it. Otherwise, it shows the view and allows that view to perform any onHistoryEvent actions it may need to take.

For example the historyStack /HOME/CURRICULUM_HOME/COURSE_PROPOSAL would start at the root controller, and hand it off to the home controller, then the curriculum home controller, then the course proposal controller and stop there. Along the way each of those controller would show themselves visually in the UI, if they contain any layout (some do not).

Specified by:

onHistoryEvent in interface HistorySupport

Overrides:

onHistoryEvent in class Controller

See Also:

HistorySupport.onHistoryEvent(java.lang.String)

getProposalTitle

private String getProposalTitle()

getCourseId

public String getCourseId()

getCourseState

public String getCourseState()

isNew

public boolean isNew()

getReqDataModel

public CourseRequirementsDataModel getReqDataModel()

Specified by:

getReqDataModel in interface HasRequirements

getReqDataModelComp

public CourseRequirementsDataModel getReqDataModelComp()

getExportDataModel

public DataModel getExportDataModel()

Description copied from interface: ReportExport

This method needs to be implemented on every controller that want's to export the data

Specified by:

getExportDataModel in interface ReportExport

Overrides:

getExportDataModel in class Controller

Returns:

getExportTemplateName

public String getExportTemplateName()

Description copied from interface: ReportExport

This overridden method only needs to be implemented if the Generic Export reports has to be overwritten for a particular COntroller.

Specified by:

getExportTemplateName in interface ReportExport

Overrides:

getExportTemplateName in class Controller

See Also:

ReportExport.getExportTemplateName()

getExportElementsFromView

public List<ExportElement> getExportElementsFromView()

Description copied from interface: ReportExport

This method returns array of ExportElements which represent the elements on the view that must be exported

Specified by:

getExportElementsFromView in interface ReportExport

Overrides:

getExportElementsFromView in class MenuSectionController

Returns:

isExportButtonActive

public boolean isExportButtonActive()

Description copied from interface: View

This method needs to be implemented only on views that want the export button to display. The default implementation is not to display the export button

Specified by:

isExportButtonActive in interface View

Overrides:

isExportButtonActive in class LayoutController

Returns:

getStateforSaveAction

protected String getStateforSaveAction(DataModel model)

This method is used to determine which state the dto will be when making the save call. The information is used by the metadata service (along with workflow node) to determine the appropriate required indicators for field elements.

getMessage

public String getMessage(String courseMessageKey)

getCourseProposalRpcService

protected BaseDataOrchestrationRpcServiceAsync getCourseProposalRpcService()

This method exists to allow the save/get implementations defined in this CourseProposalController in this controller to be reused in the CourseAdminWithoutVersion controller. This is in an attempt prevent duplication of a large chunk of code in the CourseAdminWithoutVersion controller. Rather than have a save wrapped with proposal information, the CourseAdminWithoutVersion will override this method and return the standard course rpc service which does not use filters for proposal data.

Returns:

the course rpc service to use

getCourseProposalConfigurer

public CourseProposalConfigurer getCourseProposalConfigurer()
