isLookupFieldLevelHelpEnabled

protected static boolean isLookupFieldLevelHelpEnabled(Class businessObjectClass,
                                                       String attributeName)

Determines whether field level help is enabled for the field corresponding to the businessObjectClass and attribute name If this value is true, then the field level help will be enabled. If false, then whether a field is enabled is determined by the value returned by isLookupFieldLevelHelpDisabled(Class, String) and the system-wide parameter setting. Note that if a field is read-only, that may cause field-level help to not be rendered.

Parameters:

businessObjectClass - the looked up class

attributeName - the attribute for the field

Returns:

true if field level help is enabled, false if the value of this method should NOT be used to determine whether this method's return value affects the enablement of field level help

isLookupFieldLevelHelpDisabled

protected static boolean isLookupFieldLevelHelpDisabled(Class businessObjectClass,
                                                        String attributeName)

Determines whether field level help is disabled for the field corresponding to the businessObjectClass and attribute name If this value is true and isLookupFieldLevelHelpEnabled(Class, String) returns false, then the field level help will not be rendered. If both this and isLookupFieldLevelHelpEnabled(Class, String) return false, then the system-wide setting will determine whether field level help is enabled. Note that if a field is read-only, that may cause field-level help to not be rendered.

Parameters:

businessObjectClass - the looked up class

attributeName - the attribute for the field

Returns:

true if field level help is disabled, false if the value of this method should NOT be used to determine whether this method's return value affects the enablement of field level help
