Hello, folks, I'm in need of a little help... I have a module with 3 types of node. Node A, B and C. I am trying to do something like A is the main node and B & C references A. So that, when I show the node A (teaser or full node), I get some informations about nodes type B and C that makes reference to A. Also, I want to node types B and C have a reference to the parent (A). When the user inserts the data, it must be transparent to him as who the parent is (like there is a link on node type A that allows the user to create type B or C and the node creation page will not ask the user who the parent is). The only creation method shoud be like this for nodes B and C (there should not have a link on the node creation list. Just for type A) I took a look at the project module, but I couldn't get much out of it... Any help is appreciated... Thanks, - Luis Sergio Moura
