I developed a solution where some data is imported from an extern database. Every once in a while is gives the following error.
I think it’s when a search is comitted, but I’m not sure, because sometimes the ‘Show All’ function gives the same error.
I think it has something to do with packets that are lost/broken connection. But I’m not sure. The problem is that servoy produces a popup screen with this error, and than is continues with the method it’s in, but without al the information from the extern database.
Because it’s an extern database I’m not sure what the version of mysql is.
My computer runs
