B4J Question ListofArrays -

[Johan Schoeman]

I am trying to run the server example here:

[B4X] jRDC3 - remote database connector

This is version 3 of the beloved RDC / jRDC feature - a middleware server that makes it simple to safely connect clients and remote SQL database servers. This update simplifies the clients API (the previous API was implemented before Resumable Subs feature was fully implemented). The data...

www.b4x.com

In Class RDCHandler of RDC-Server there is this line of code:

res.Rows = lres.mInternalArray.SubList(lres.mFirstDataRowIndex, lres.mInternalArray.Size)

B4J reports this as

Unknown member: sublist
Unknown member: sublist
RDCHandler - 97: Unknown member: sublist

How do I sort out this error that I am getting?

You need to use latest version of B4J.

Thanks Erel - thought it might be the case but have not yet downloaded latest version on this laptop

For completeness - in the latest update there is a new List.SubList method that returns a read-only partial list that is based on the original list. This is a very quick operation as it only needs to update the indices of the new list. No data is copied.
