Hello Roland,
I found a serious issue after updating to RO CSVI 9.9.0.
My custom export files were stored in:
/components/com_csvi/src/File/Export/Xml
After updating the component, these files were removed. Unfortunately, I lost my custom export work and now I need to restore the Joomla site from a backup to recover them.
I tested this on another website as well and the result is the same, so it does not look like an isolated case or a coincidence. It seems the component installer replaces or cleans this folder during the update.
I think a safer place for this type of custom file would be outside the component installation directory, for example in a dedicated custom folder, similar to how Joomla template overrides are stored. Files placed inside the component’s own installation path are too easy to lose during an update.
Regards,
Chris
