Embedding the Designer in a TFrame object

rbuser

Hello,

I'm doing some tests with delphi5 and ReportBuilder 5.56 Professional
Edition.
Everything works fine until I try to embed the Designer to a TFrame object
by setting the Designer.Form.Parent to a Panel inside the TFrame.
If I try to add any object to the detail band at run-time I get an
EOutOfResource or EAccessViolation error.

What is the problem ??

From our release notes:


2. Issues with Frames



Delphi 5 Frames (TFrame) are containers that enable collections of
components to be visually configured and re-used. Unlike form inheritance,
however, Delphi 5 does not permit new components to be added to frame
descendants (i.e. frames embedded on forms or other frames).



Therefore, if a Report object is placed on a frame, the report layout must
be maintained entirely in the top level ancestor. You cannot access a form
containing the frame and add report components, nor can new report layouts
be loaded from templates.



ReportBuilder's DBPipeline and BDEPipeline components cannot currently be
used with frames. Both of these components automatically create Field
components (i.e. AutoCreateFields) when a dataset is opened. This behavior
will cause access violations if a data pipeline is placed in a descendant
frame.
