Hello,

It has been replaced by a groovy validator that is easier to work with. See following example.

if your widget is named file1, the groovy validor should take into parameter :

field_File1.getFileName().contains(".xls")

Thanks

Hi,
I think it’s better to use the endsWith method.

field_File1.getFileName().endsWith(“.xls”)

Thank you very much!!
Now as I assign the attachment to a process variable, I have read that a document is created in the pool, but when I do the assignment in the option data widget shows me the following error: “expression document type is not supported”
