Jan, I realize it's been 6 years since your post, but I'd like to know if you experienced this:
View Source is in a separate NSF, a mail file.
I'm using the UNID selection technique of the View PickList
Everything works fine and dandy in its own XPage with 1 loading mask and 12 instances (for each month) in my example.
HOWEVER when I integrate it either by using an INCLUDE XPAGE or by pasting the contents into its place in the calling XPage Tabbed Panel, the View Source becomes a random view in external database where my data resides (I keep the Xpage code in a separate NSF).
I'm using Domino Notes 9.0.1 FP9 SHF55 and View Pick List v3.0.
And if you did experience the above, how did you overcome?
