The exception being raised is due to there being a BLOB column that should have its contents loaded if it isn’t null. Somehow there is the condition in your application that you have a non-null blob column that also does not have a value loaded. Will you please provide me with a sample application that reproduces this condition?

Subject: [IBO] Huge problems since updated from 4.8 to 5.9.x
Since I wanted to migrate my applications from FB2.5 to FB3, I needed a new version of IBO. I upgraded from 4.8 to the latest version. Now I have huge problems.
First on is a big decrease in performance when using TIBCTRL_Grid. I allready sent a demo program, where this issue is fully reproducable to Jason weeks ago, but did not hear any news since than.
Now I discovered another, even bigger problem.
When I have a TIBO_Query and call Edit, it raises an assertion Exception. Debugging shows me that it is in the unit IB_Components at the method TIB_DataSet.SysUpdateOperation
in the line with
Assert( (tmpCol as TIB_ColumnBlob).IsLoaded );
No idea why this raises that exception.
I am close to go back to IBO 4.8 and then try to replace IBObjects by IBDAC in my older programs that I have to keep in Delphi 2007. The newer ones are allready in Delphi 10.1 with IBDAC and they work fine with FB2.5 and FB3.0.
At the moment I am really disappointed with IBObjects and the support after having it used since the year 2000.
