When you change fields on your grid (ie. by the menu item field positioning) then after change the details are empty:
I added an extra field to the query: MONTHS_BETWEEN (SYSDATE, birthdate) / 12 AS age,
If I put this field on the grid, the details will be empty, if you remove it from the grid, the details are shown.
By the way, I have some samples where it’s completely unclear why the details are empty.
You’re probably going to have to put together an example, Albert.
I have a lot of grids with added fields, similar to what you described, and the data is filled in the grid and the detail.
One possible difference: I always try to use the field properties to perform tricky SELECTs v using the grid’s SQL properties. ScriptCase will mangle even simple SQL in unpredictable ways, and I don’t trust it beyond “SELECT * FROM table ORDER BY column;”
This is obviously a slower solution, but it has the advantage of only breaking one field when it’s Monday morning and your fingers are still 4 keys thick from caffeine depravation. 
Hi aducom,
I have tried to perform the same that you. I have created an grid application with the following SQL:
SELECT
PRODUCT_ID,
PRODUCT_NAME,
PRODUCT_DESCRIPTION,
CATEGORY,
PRODUCT_AVAIL,
LIST_PRICE,
MIMETYPE,
FILENAME,
IMAGE_LAST_UPDATE
FROM
DEMO_PRODUCT_INFO
And after, I added: MONTHS_BETWEEN(SYSDATE, ‘2014-12-01’) as TEST. But, the detail is showing okay. Did you do any stuff different?
Not too long ago i had the same bug without any usage of MONTHS_BETWEEN(), but just empty details on some of my grids. It seemed difficult to reproduce as sometimes suddenly the details would be filled just by switching some fields to the ‘not shown’-page. Anyways i don’t seem to be getting the bug anymore (had details switched off for a bit since i encountered it, just put it back on, seems all good).
