ProgramController

public ProgramController(String name,
                         DataModel programModel,
                         ViewContext viewContext,
                         com.google.gwt.event.shared.HandlerManager eventBus)

Constructor.

Parameters:

programModel -

Method Detail

createProgramRemoteService

protected MajorDisciplineRpcServiceAsync createProgramRemoteService()

Create a ProgramRpcServiceAsync appropriate for this Controller

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)

fireUpdateEvent

protected void fireUpdateEvent(Callback<Boolean> okToChange)

resetModel

protected void resetModel()

resetFieldInteractionFlag

protected void resetFieldInteractionFlag()

initializeModel

private void initializeModel()

Initialized model of the controller.

requestModel

public void requestModel(Class modelType,
                         ModelRequestCallback callback)

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

loadModel

protected void loadModel(ModelRequestCallback<DataModel> callback)

Loads data model from the server.

Parameters:

callback - we have to invoke this callback when model is loaded or failed.

setModelData

private void setModelData()

getProgramViewLocation

private String getProgramViewLocation(String pgmType)

setStatus

protected void setStatus()

getProgramName

public String getProgramName()

beforeShow

public void beforeShow(Callback<Boolean> onReadyCallback)

Got invoked by framework before showing the view of the controller.

Specified by:

beforeShow in interface View

Overrides:

beforeShow in class LayoutController

Parameters:

onReadyCallback -

See Also:

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

loadMetadataCondition

protected boolean loadMetadataCondition()

We should only load metadata if the status of model is changed.

Returns:

loadMetadata

protected void loadMetadata(Callback<Boolean> onReadyCallback)

Loads metadata from the server.

Parameters:

onReadyCallback -

configureView

protected void configureView()

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

afterMetadataLoaded

protected void afterMetadataLoaded(Callback<Boolean> onReadyCallback)

Called when metadata is loaded.

Parameters:

onReadyCallback -

setHeaderTitle

protected void setHeaderTitle()

createCommentPanel

protected com.google.gwt.user.client.ui.Widget createCommentPanel()

doSave

protected void doSave()

updateState

protected void updateState(String state,
                           Callback<Boolean> okCallback)

Update the state of the program and all of its statements.

This is only called when the state change event fires.

There are several types of programs (majorDiscipline, core, credential). The state of each program changes when buttons are pressed. For example, pressing the activate button may change the state of the program from draft to active.

This method is triggered when the state changes. It will pass the new state to the controller servlet, which will then use it to update the state by calling the web services.

Note that state and status are different.

It is placed in ProgramController so core, credential, etc all have access it.

Parameters:

programModel - a map containing data representing the program

state - the state we changed to

callback - will return true if update succeeded

refreshModelAndView

public void refreshModelAndView(DataSaveResult result)

This method will refresh the model and view with the data sent back from the server.

getProgramModel

public DataModel getProgramModel()

onModelLoadedEvent

public void onModelLoadedEvent()

getStringProperty

protected String getStringProperty(String key)

getDataProperty

protected Data getDataProperty(String key)

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:

getExportElementsFromView

public ArrayList<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:
