We have detected inconsistences between the resources created or updated on the 6.4.3 versión and the export/import of them on the 6.3.0, because it's neccesary to edit the TopicJRXML.data file of each resource to import it corretly) During this time we have installed the 6.4.3 versión on a new enviromment to make all type of configuration changes and tests, but the problem is that the application don´t show any error in the log files, so we are thinking that could be a bug on the application that don´t cause any exception.
