looking library work large numbers on javascript (bigger 2^53) checked couple of questions ( javascript large number library? , is there bignum library javascript? ) , tinkered little bit javascript-bignum.js , big.js , thing unable represent odd numbers, since both big(9007199254740995); and schemenumber.fn["string->number"](9007199254740995); return 9007199254740996 rather than 9007199254740995 as expect. so, doing wrong? or there's no way represent large odd numbers? when big(9007199254740995) you not giving bignum library chance! numeric literal first parsed pure js, in number isn't representable. can see with window.alert(9007199254740995); which alerts 9007199254740996 . in order let chosen bignum library represent number, need pass string , example: big('9007199254740995') should exact number, bignum.

i've found utterly hilarious bug when i've been trying debug wix installer's custom actions. i didn't write code, somehow 1 of 3 managed .dlls decides invisible main .dll, that's referenced , called wix, when turn optimisations off (to debug) main .dll. as understand, multiple dependencies in wix difficult or impossible without using tool ilmerge , i'll end splitting down own separate .dlls , have loads of custom actions instead. the main question here is: ( out of pure curiosity ) why dependencies loading when optimisations enabled , not without them being enabled?

situation: moving using struts 1 struts 2. in struts 1, necessary form classes follow javabean specification. since business data objects immutable, required creating javabean version of many classes, , methods mapping between two. does struts2 support using immutable objects forms? if so, how configure such immutable object instantiated builder using form fields? the object being populated request can't immutable, because ognl calls setters on it–that's how ognl (and els) work. i figure have 2 options: either custom parameters interceptor, or create constructor or builder takes bean used form. without real thought, i'd latter, although might create quick tool generate form classes if there lot of them. interceptor more elegant, it'd need use reflection.
