Exception when create private data source(with private module)
-
Hi supporter,
We met an exception when save a data source (private module) first time. After reboot the core, this exception disappears, new data sources and related new dara points work fine.
Could anyone help take a look? How could this type-mismatch happen between DP and DS?
Thanks

Hi Mebius,
The error is as described, there is a mismatch in point type. Either this is in your code in the data source definition class you didn't define a unique data source type, or (more likely) you used another tab to browse either a data source or data point, which due to some state saved on the server in the user's session, then tried to perform an action which had relied on the state being another way. Eventually, it is our intention to remove a lot of this state tracking, but lots of pages use DWR so it is not a small effort.
To know if that is it, you would just have to edit the point again (click the pencil) and try to make your changes and save it again.
