Examples of play.data.binding.ParamNode.removeChild()

play.data.binding.ParamNode.removeChild()
Removes a child from this node, but stores what is removed to list. The we can later call which will add it back again. This is a "hack" related to #1195 which makes it possible to reuse the RootParamsNode-structure if you want to perform the bind-operation multiple times. @param name the name of the child-node in this paramNode which should be removed. @param removedNodesList a list where info about what is removed where is stored. @return true if anything was removed.

                            String[] ids = fieldParamNode.getChild(keyName, true).getValues();

                                // Remove it to prevent us from finding it again later
