UIData and large data. Change int to long about javaserverfaces-spec HOT 12 CLOSED

@edburns said:
Changing this would break binary backwards compatability for those that
subclassed UIData.

Have to ask the EG about it.

Based on EG feedback, I am closing this issue (at least for 1.2).
What Adam suggests sounds like the right approach.

Thanks, Roger.

Erm, regarding UIData, why do we care about longs?

For a scroller component, yes, but it's not as if
anyone is going to actually show greater than 232
rows of data at any one time. You could use a UIData
to show windows of data into a "long" dataset; you'd
just have to be more careful with the model and the
scroller.

BTW, we'd also have to change DataModel, or introduce
a LongDataModel.

The javax.sql.RowSet uses an int for a row and so does
java.sql.ResultSet-- a long? wow.

add:

abstract long getRowCount();
abstract long getRowIndex(); //this can be an issue because Collection.size() returns int..so only can be used on lazy loading

to

javax.faces.model.DataModel

this way lazy loading for huge Data Set is allowed and backwards compatibility is mantained
