Hi,

Forgive me if there is a better location to post this question or if it may have been answered some time in the past. I tried searching but can't find an answer to it.

If I have a DataObject for tracking purposes that has no $db component, just 3 $has_one components, roughly like:

Location (which is an object that inherits from Page)
Trial (which is an object that inherts from Page)
member (which is an object that inherits DataObject)

I create a new one of these tracking objects at certain points and write them to the database manually.

On the customer end, It is used mainly for searching the data on the various fields. Now this dataobject works perfectly fine
everywhere except for searching through ModelAdmin.

So far, the main search items are the Title fields from the two"Page' inherited objects and some fields from the other. When trying to run the search for say: Location of "Mars", I get this error... this happens with either of the Page inherited objects.

- SELECT DISTINCT COUNT(DISTINCT Tracking.ID) AS TotalCount
- FROM `Tracking`
- LEFT JOIN `Location` ON `Location`.`ID` = `Tracking`.`LocationID`
- WHERE (`SiteTree`.`Title` LIKE '%mars%')

- Unknown column 'SiteTree.Title' in 'where clause'

I can see why there is an error as SiteTree isn't being joined into the Query.

Is this fixable which some simple setting/methodcall?

Thanks!
