Why does WebApplication.SendFile fail with “Reply type already set”?

Question

Steps:

1. I created a new IntraWeb application using the IntraWeb Application Wizard.
2. I put a TIWButton on the form.
3. I put this code in to the OnClick event handler:

WebApplication.SendFile('D:\Temp\ClearAll.sql');

Clicking on the button raises an exception of type Exception with the message Reply type already set.

Any ideas what's going wrong?

Delphi is XE3 with IntraWeb XIV.

I tried the same with Deplhi 2007 (IntraWeb 9) and it works, so this seems to be a bug in IntraWeb XIV.

Can sombody please confirm this?

Answer 1

This is indeed a bug as confirmed by Jackson Gomes:

I found out that this doesn't happen on XE2 with Intraweb XII. So it seems to be a bug in Intraweb XIV or Delphi XE3.

correct

In addition we know have a registered copy of Delphi XE3 and Intraweb XIV still switches ports randomly (e.g. doesn't use the port I specified in the server controller).

We will check it... thanks
