Member	eric.rovtar - 1/20/2011 4:52:33 PM Modifying Pre-Defined Types Hi! Would it be wrong to add a custom field/attribute to the CMS.Page document type? I foresee this becoming a problem in upgrades. Is it best to create my own Page document type? Thanks! -Eric

RE:Modifying Pre-Defined Types

Hello.

There should be no problem with custom field added into pre-defined document type in order to a future upgrade procedure. I mean during upgrade procedure custom fields should not be re-written and lost. Moreover, this is common operation and many our customers are using modified document types in upgraded version with no problem. Did you try it and encountered some particular problem or you just want to be sure? Thank you.

Best Regards,
Radek Macalik

RE:Modifying Pre-Defined Types

I didn't try it yet. I just wanted to check before doing it. When I tried upgrading from 5.5 to 5.5R2, I got an error that I thought was due to my modifications to the CMS.File type, but maybe that wasn't it.

I suppose it's always better to do a clean install anyway. In which case, I can then readd the custom attribute to the type before importing the site objects.

Thanks!

However it should be possible to upgrade project with modified document type as well. If you encounter any problem during upgrade process, you can post its details here and we will try to help you. Thank you. Best Regards, Radek Macalik
