"Index out of bounds" error exporting in Excel from Visual Composer

Hi all,

I use Visual Composer In NWDS 7.3.

I created a model with an external composite view as model and various tables to create a report.

I used many VC functionality. One of this is the export functionality.

This functionality add an Export button on my tables for export data in Excel format. For some tables this functionality works right. In other cases I obtain an "index out of bounds" error, also if the table is not empty.

The detailed error is this:

java.lang.IndexOutOfBoundsException: Node(Launcher.0DAF04CDD6.G_UI/VCSearchUserComp.Users.0.Accounts, class=com.fiat.sc.vc.wd_serch_user.wd.comp.vcsearchusercomp.wdp.IPublicVCSearchUserComp$IAccountsNode): index out of bounds: index=0, size=0

Any suggestions? All the scn question I've found are referring to NWDS 7.0 and to this document

But this is not my case...

Thank you all for your help.
