We seem to have encountered an issue with copying and posting from grid views based on data trees. The following occurs:
I have a table called Batches, which contains a string column name ProjectCode. A second table is called Storage, which also contains a string column called ProjectCode. They are linked using a One-To-Many relationship (from Batches to Storage).
If I now create a data tree starting from the Storage table and add the Batches table as an edge (using the relationship described above), I can make a combined Grid View showing columns from both tables. So far all goes fine.
However, it turns out that it is not possible to copy-and-paste any of the fields coming from the Batches table in the combined grid view into another application. Most simple example: if I show both ProjectCode columns side-by-side I can copy the column coming from the Storage table into for example Excel, but I cannot copy the column coming from the linked Batches table.
To be clear: the copy option is available, and does not give error. However pasting in another application (such as Excel or a text editor) gives nothing...
Is this expected behaviour?
