problem with copying data from node to node (cardinality 0..n)

[Former Member]

Hello to all,

I have a problem with copying data from one node to an other.

There is a node named "info1" with cardinality 0..n and selection 0..1 with 25 attributes.

The other node "copy1" has cardinality 0..n and selection 0..1 with but only 20 attributes, but this attributes are also in the node "info1".

How could I copy all the information in "info1" into "copy1"?

If i copy attribute by attribute with den gerenated code, I alway get an error like something about Null objectreference or so...

If I make the cardniality of "copy1" to 1..1 an also the selection to 1..1, there are no errors.

Could you help me?

Is this right, if i write this in wdinit?

Change cardinality of 'info1' and 'copy1' to 1..n. And then check if it works.
