Method Detail

initBeanPropertyAccess

public void initBeanPropertyAccess()

Allows for a custom binding result class.

Overrides:

initBeanPropertyAccess in class org.springframework.validation.DataBinder

See Also:

DataBinder.initBeanPropertyAccess()

getInternalBindingResult

protected org.springframework.validation.AbstractPropertyBindingResult getInternalBindingResult()

Allows for the setting attributes to use to find the data dictionary data from Kuali

Overrides:

getInternalBindingResult in class org.springframework.validation.DataBinder

See Also:

DataBinder.getInternalBindingResult()

initDirectFieldAccess

public void initDirectFieldAccess()

Disallows direct field access for Kuali

Overrides:

initDirectFieldAccess in class org.springframework.validation.DataBinder

See Also:

DataBinder.initDirectFieldAccess()

bind

public void bind(javax.servlet.ServletRequest request)

Performs data binding from servlet request parameters to the form, initializes view object, then calls UifFormBase.postBind(javax.servlet.http.HttpServletRequest)

The view is initialized by first looking for the viewId parameter in the request. If found, the view is retrieved based on this id. If the id is not present, then an attempt is made to find a view by type. In order to retrieve a view based on type, the view request parameter viewTypeName must be present. If all else fails and the viewId is populated on the form (could be populated from a previous request), this is used to retrieve the view.

Note the view is not initialized for Ajax requests that perform partial page updates or dialog updates or no updates at all

Overrides:

bind in class org.springframework.web.bind.ServletRequestDataBinder

Parameters:

request - - HTTP Servlet Request instance

getViewByType

protected View getViewByType(javax.servlet.ServletRequest request,
                             UifFormBase form)

Attempts to get a view instance by looking for a view type name in the request or the form and querying that view type with the request parameters

Parameters:

request - request instance to pull parameters from

form - form instance to pull values from

Returns:

View instance if found or null

getViewFromPreviousModel

protected View getViewFromPreviousModel(UifFormBase form)

Attempts to get a view instance based on the view id stored on the form (which might not be populated from the request but remaining from session)

Parameters:

form - form instance to pull view id from

Returns:

View instance associated with form's view id or null if id or view not found

getViewService

public ViewService getViewService()
