|
||
|
|
// TEST: allow client-side paging (return all data initially, set paging:{pageSize:#}, and ensure maxCacheBytes is > 0)
|
||
|
|
// TEST: accept json object as first parameter to flexbox instead of page source, and have it work like a combobox
|

// TEST: implement no results template
|
||
|
|
// TEST: implement noResultsText and class

// TEST: how can we allow programmatically setting the field value (and therefore hidden value). add jquery function?

// TEST: use pageSize parameter as threshold to switch from no paging to paging based on results
