getFormMap

public static FormMap getFormMap(javax.servlet.http.HttpServletRequest request)

Parameters:

request - the HttpServletRequest

Returns:

a populated FormMap for the formdata node belonging to the UUID from request parameter u_u_i_d If there is no formdata for the UUID or no u_u_i_d parameter, just an empty FormMap object will be returned

See Also:

#populate(javax.servlet.http.HttpServletRequest, FormMap)}

populate

public static void populate(javax.servlet.http.HttpServletRequest request,
            FormMap formMap)

This method tries to repopulate an earlier posted form that was stored in the repository. Only when there is a request parameter containing the correct uuid, it can be re-populated.

Parameters:

request - the HttpServletRequest

formMap - a not yet populated FormMap object (just new FormMap())

populate

public static void populate(HstRequest request,
            FormMap formMap)

This method tries to repopulate an earlier posted form that was stored in the repository. Only when there is a request parameter containing the correct uuid, you can re-populate it.

Parameters:

request - the current hstRequest

formMap - the formMap that will be populated

See Also:

rather use {@link #populate(javax.servlet.http.HttpServletRequest, FormMap)} instead of this method

persistFormMap

public static void persistFormMap(HstRequest request,
                  HstResponse response,
                  FormMap formMap,
                  StoreFormResult storeFormResult)
                           throws HstComponentException

Facility to temporarily store submitted form data which needs to be accessed in the rendering phase again. This method add the uuid of the newly created jcr node on the response as a render parameter

Parameters:

request - the request

response - the response

formMap - the form names + values to temporarily store

storeFormResult - an object to store some result of the data persisting, for example the uuid of the created node

Throws:

HstComponentException - when the storing of the formdata fails

validateId

public static void validateId(String uuid)
                       throws IllegalArgumentException

Validates an uuid. If invalid uuid is passed, IllegalArgumentException exception will be thrown

Parameters:

uuid - uuid to validate

Throws:

IllegalArgumentException - thrown on invalid uuid

getWritableSession

public static javax.jcr.Session getWritableSession()
                                            throws javax.jcr.RepositoryException

Throws:

javax.jcr.RepositoryException
