Can I modify TfrDBDataset.FieldAliases after save templates?

edited November 2008 in FastReport 4.0
I already save a lot of templates. Now I must change the alias name by code.
When I Preview the old templates, I get Error Message "XXX" can't found.

How can I do?

why the fr's Control.DataField property don't save orial fieldname, only in display show alias name?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
