Hello,
I just moved to gephi 0.9.1 from gephi 0.8.2. I'm trying to add some columns to my nodes data table and I get the following error:

java.lang.IllegalArgumentException: The id class does not match with the expected type (java.lang.Integer)
at org.gephi.graph.impl.NodeImpl.checkIdType(NodeImpl.java:248)

at org.gephi.datalab.api.DataLaboratoryHelper$5.run(DataLaboratoryHelper.java:325)

I don't understand what's happening. I'm creating the csv file exporting from gephi and then I add new data in Excel.
I have tried with example network Les Miserables and it works fine, so it is probably something in my network, but no clue on what can it be.
Only thing different I've noticed from gephi 0.8.2 is that node's Ids no longer have decimal point, before I had: 0.0, 1.0... now I have: 0, 1...
Any suggestions?
Thank you.
