Method Detail

checkForm

public org.springframework.web.servlet.ModelAndView checkForm(UifFormBase form)

Invokes ViewValidationService to validate the contents of the given form instance. Handles the check form action to validate the given form data.

Specified by:

checkForm in interface ModelAndViewService

Parameters:

form - instance containing the model data

Returns:

ModelAndView instance for rendering the view

showDialog

public org.springframework.web.servlet.ModelAndView showDialog(String dialogId,
                                                      boolean confirmation,
                                                      UifFormBase form)

Builds the dialog group with the given id then creates the script for showing the dialog once the page reloads. Invoked by controller methods to show a dialog to the user.

This will return back to the view and display the dialog to the user. When the users chooses a response, the initial action that triggered the controller method (which called showDialog) will be triggered again. The response will be captured in the form property UifFormBase.getDialogResponses(). In the case of a confirmation, if 'false' (typically labeled cancel) is choosen the initial action will simply not be triggered again.

Specified by:

showDialog in interface ModelAndViewService

Parameters:

dialogId - id for the dialog group to show

confirmation - whether the dialog should be shown as a confirmation, in this case it is expected the options are true (continue) or false (stop). In addition, if the user selects the false option, the dialog answer will not be resubmitted to the server, instead the user will remain on the view

form - instance containing the model data

Returns:

ModelAndView instance for rendering the view

buildShowDialogScript

protected String buildShowDialogScript(String dialogId,
                           boolean confirmation,
                           UifFormBase form)

Builds a JavaScript string for invoking the showDialog method with the given dialog parameters.

Parameters:

dialogId - id for the dialog group to show

confirmation - whether the dialog should be shown as a confirmation

form - instance containing the model data

Returns:

String containing script

performRedirect

public org.springframework.web.servlet.ModelAndView performRedirect(UifFormBase form,
                                                           String baseUrl,
                                                           Properties urlParameters)

Builds an URL from the given base URL and parameters, then builds a model and view instance configured to redirect to the built URL.

Specified by:

performRedirect in interface ModelAndViewService

Parameters:

form - form instance containing the model data

baseUrl - base URL to redirect to

urlParameters - parameters to add to the base URL

Returns:

ModelAndView instance configured to redirect to the built URL

performRedirect

public org.springframework.web.servlet.ModelAndView performRedirect(UifFormBase form,
                                                           String redirectUrl)

Builds a model and view instance configured to redirect to the given URL.

Specified by:

performRedirect in interface ModelAndViewService

Parameters:

form - instance containing the model data

redirectUrl - URL to redirect to

Returns:

ModelAndView instance configured to redirect to the given URL

getMessageView

public org.springframework.web.servlet.ModelAndView getMessageView(UifFormBase form,
                                                          String headerText,
                                                          String messageText)

Retrieves an instance of the view with id UifConstants.MESSAGE_VIEW_ID and sets the header and message from the given parameters. Builds a message view from the given header and message text then forwards the UIF model and view.

If an error or other type of interruption occurs during the request processing the controller can invoke this message to display the message to the user. This will abandon the view that was requested and display a view with just the message
