Removing an attribute from a group by clause

Question

This concerns a web application developed by JDeveloper 10.1.2 (adf, uix). I have viewobject with a query, written in expert mode, that has a group by clause. I removed an attribute from the select statement that was included in the group by clause and removed it from the bindings of the page that displays the data from the view. When I test the application module the data is grouped correctly. But when I run the view the attribute is not shown on the page but the data is still grouped by the attribute. The same query works fine in SQL plus, it looks like JDeveloper 'remembers' the old group by clause somewhere. I checked the xml file of the view object and it looks ok. Where can the old group by clause be written? How comes it is still applied?

I am trying to place a shape on an image and remove it from the photo, creating just the picture within the shape.  When I follow instructions, I get a lovely shape around my image, but the image isn't removed.  It just sits in a white-checkered background.
How do I get rid of the white background?
The white-checkered background is a visual reference for transparency. (It won't print.) To keep the transparency, you need to save in a format that supports transparency, PSD, TIF (with save transparency checked), PNG, or GiF. If you save in a format such as JPG that doesn't support transparency, the transparency is replaced by white.
Edit: If you are transferring the image into another software application, you may have to save the selection along with the image. Select<Save Selection. You'd have to also check which of the formats that application accepts.
