Hi, I am seeking some help or links to documentation with IDataProvider for DataView.
In my use case the size of the data grows while the user clicks through list pages. I wrote an IDataProvider implementation that progressively returns larger values with the size() method. However it fails due to the size growing, if the user clicks on the last page. That is because DataView limits itself understandably, by only requesting as many rows as the last invocation of size() tells it are available. But this limitation is unnecessary. What is needed is that it keeps filling the page until the Iterator for IDataProvider.iterator(int first, int count) returns false with hasNext(), or until its page is full, in that case displaying a link to the next page, ignoring the fact that size() is no longer accurate. I hope that an easy solution for this requirement exists as I think that there is no conflict with out-of-the-box correct behavior. Again, very specifically, during the same cycle, after the underestimated size() result, the iterator may return more data than expected, and that excess data should be consumed normally in such a way that the user can continue moving forward to subsequent pages as long as more data becomes available. Many thanks!
