[bv-dev] Creating custom nodes in cross-parameter constraint validators

Hi, We added the method addParameterNode() to the node builder API, allowing for the creation of custom subpaths in cross-parameter constraint validators. Currently such a path will look like this (the first two nodes are the default ones, the remain ones are custom created nodes): METHOD -> CROSS_PARAMETER -> PARAMETER -> ... I'm wondering whether it wouldn't be better to get rid of the cross-parameter node in this case: METHOD -> PARAMETER -> ... E.g. when looking at the following example: @OldAndNewPasswordDifferent public void resetPassword(String new, String old) { ... } Then I think the following path might be what constraint authors want: MethodNode("resetPassword") -> ParameterNode("old", arg1) As it seems, the RI does the same when custom nodes are added in class-level constraint validators (i.e. no node for the class-level constraint will be part of the path). Shortly looking in the spec, I couldn't find an example mandating this behavior, though. Any thoughts? --Gunnar
