getActionParameters

public Map<String,String> getActionParameters()

Description copied from interface: ViewModel

Map of parameters sent for the invoked action

Many times besides just setting the method to call actions need to send additional parameters. For instance the method being called might do a redirect, in which case the action needs to send parameters for the redirect URL. An example of this is redirecting to a Lookup view. In some cases the parameters that need to be sent conflict with properties already on the form, and putting all the action parameters as form properties would grow massive (in addition to adds an additional step from the XML config). So this general map solves those issues.

Specified by:

getActionParameters in interface ViewModel

Returns:

Map action parameters

Returns:

String action event name or blank if action event was not sent

Specified by:

getClientStateForSyncing in interface ViewModel

Returns:
