google app engine - GAE/J after upgrade to 1.9.3 can not retrieve child records in one to many relationships -


i trying upgrade app gae 1.8.1 1.9.3, apparently there 1 major issue retrieving child records in 1 many relationship have.

in old version using datanucleus jdo version 1 , worked fine. using version 2.

after upgrade can retrieve parent objects (the child nulls), although when create new data seems working fine.

i checked how new data looks in database viewer, , seems one-to-many column in class of old data labeled "missing".

if create new data data filled index information.

i appreciate

update apparently datanucleus jdo version 2 not backward compatible version 1. if you're going consider upgrade verified data relationships not broken (like mine did)

my current solution stay version 1 , use newest gae sdk (which seems working well)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
