Hello,

The 'Connection is not defined' error means that you did not define a connection for a dataset for which you are trying to use Fields Editor. To solve the problem, you should set the Connection property of the dataset to one of the TIBCConnection components that you have on your form. If you do not have any TIBCConnection components on the form, you should drop it onto the form from Tool Palette.

Component on the form, there TIBCConnection.

[AndreyZ]

Please make sure that the Connection property of the dataset is set to this TIBCConnection.

transaction component design mode "active = false" This problem occurs when

[AndreyZ]

Please perform the following steps:
- open Delphi XE2;
- create a new VCL Forms Application;
- drop the TIBCConnection component onto the form (it will be named IBCConnection1);
- drop the TIBCQuery component onto the form (it will be named IBCQuery1). Note that IBCQuery1.Connection will be already set to IBCConnection1;
- right click on the IBCQuery1 component and choose Fields Editor;
- right click in the editor and choose Add Fields.
After you perform these steps, you will see the connection dialog prompting connection options. The connection dialog occurs because to add fields, they must be obtained from the server. This is a correct way to work with datasets. Connection must be defined for datasets that obtain any data from the server.
