I am still new to Cuba. I have created a new entity with its standard screens.
At a later stage, I want to convert a field (created as textfield by default) to a checkbox. However, I am not able to do that from Studio. I can only select the fieldgroup, and cannot really modify the settings of a field.
I tried deleting the textfield, and adding a new checkbox from the palette, but for some reason, I cannot insert it in the field group. So the layout looks messy.
What is in general the best approach to modify the types of existing fields?
