Sorry, no, you're not rebuilding this index online as you never told Oracle you wanted to do that by using the ONLINE directive in the ALTER INDEX statement:
Alter index rebuild textidx1 online;

And it should; ONLINE rebuilds only allow DML on the base table, not queries OF the base table. The documentation clearly states this.

You're not rebuilding online, and even if you were the error WILL still occur because queries against the base table are not permitted during a rebuild, online or not.

It allows OLTP applications to continue to insert/update/delete data in the base table so people can continue working.

Stop trying to query the base table while the rebuild is in progress.

And you don't have to stop your application, you simply need to learn how to actually do an online index rebuild and stop trying to query the base table while the rebuild is occurring.
