Question

I am using Delphi 2010 and GExperts stable release 1.35

I am testing the “Replace Components” expert.

I add a main form and a secondary form. Each has three TEdits on it.

I use the Replace Components Expert to replace all TEdits with TRzEdit. I Check the Replace all components on all forms of the project.

It works, it replaces them all. However, it doesn’t do anything to the DFM file. How do i make it replace those instances.

If i save, compile, or rebuild, i get errors.

If i try to view the form as text after replacing, i get errors.

Can someone explain to me the steps to make this work?

Thanks

You might be running into this bug while trying to copy the Touch property from the old to the new component, but it has a workaround you can fairly easily test:
http://tech.groups.yahoo.com/group/GExpertsDiscuss/message/3994

Details:

There is a limitation/bug in Delphi 2010 and XE where if you assign a
Component.Touch property from one component to another and destroy the
original component that the new component becomes corrupt (it isn’t
like component/interface references, where they either auto-correct
themselves or are reference counted).

For the moment, you can assign a bi-directional replace component
property map from TPanel.Touch to TGroupBox.Touch (use the two components being replaced in your specific case) that is marked as
a disabled property map, and that will work around this problem. Our next release
will not try to assign that property any longer.

GExperts 1.36 is also now available and includes a workaround for this issue. The workaround has been in the GExperts version control system and in testing for several weeks already.
