A web component might want to work with as many dataproviders available in the viewport as the developer wants. Servoy Developer will allow selecting any number of dataproviders of the foundset to be sent to browser web component property value (through the properties view for the foundset typed property; after you select a foundset you can edit the list of dataproviders that appears by changing it's size and choosing dataprovidersuse sub-property 'dataproviders').

For example a component that shows graphical representation of data might allow adding as many 'categories' to it as the developer wants to (each category getting data from one viewport column/dataprovider) .

...

A web component can specify in it's .spec file that it requires a foundset property and a fixed number of dataproviders from it. The foundset and required dataproviders are then selected by the developer when creating a solution (using the properties view, 'dataproviders' sub-property).

.spec file

"myFoundset": { "type": "foundset", "dataproviders": ["firstName", "lastName"] }
