[Laszlo-user] Dataset as an Attribute and Tag Error

[David Buckler]

Andre

I appreciate you opening up that bug and I understand it will definitely cover the datapath attribute versus child node issue.  I am just wondering does the datapath of the second tree get set by the first tree by the instantiation, and hence causes the duplicate replicaton.  I am just confused because all I did to get the duplicate replication was move the datapath attribute out of the tree tag into a child datapath tag with an xpath of *.

I've created LPP-5193 (http://www.openlaszlo.org/jira/browse/LPP-5193)
to fix this issue.
