updating dataProvider

[allMyNicksAreTaken]

Hi, when updating the dataProvider attribute of a component, the component
doesn't update according to this new state of the dataProvider. Say i have a
LinkBar with dataProvider=links. links is an Array of objects. When adding or
removing to this array, the linkBar doesn't update. With a datagrid it is the
same problem: its dataProvider is changed, but the visualisation of the
component isn't accurate: it only displays those elements that were in the list
during initialization... Does anyone know how to update the component properly
when the dataProvider changes? greetz

Use the dataProvider API methods, not the low-level array fintionality like
"push", or myArray[n] = "whatever". These do not cause the dataProvider to
emit the modelChanged event.

Use addItem(), addItemAt() etc.

when i use the methods of the DataProvider class on an array that acts like a
DataProvider, does this mean the array itself is changed as well? Because i use
the same array over and over again for several dataProviders. When one
component changes its dataProvider, this needs to be reflected in all the
opther componets that use the same array as dataProvider... thanks

Yes, the dataProvider API works on the underlying array.
