jsp - Displaying Map keys on struts2 autocompleter tag -

-

i've been struggling while autocompleter tag using struts2 jquery plugin.

i've been able use on simple way, retrieving string lists database, wondered if fetch hashmap action , display user keys only.

the response comming action successfull, can see on chrome dev tools action returning json containing map. however, autocompleter displays te values instead of keys, want, i'm trying list addresses user , had used them keys on map, values identifiers each address.

this example should ilustrate map looks like. it's response i'm getting action call when user writes 'ho':

{"addresseslist":{"home":"-20","hotel":"-4","hooters":"-2"}}

however, when user starts writing in autocompleter, keeps showing values (-20, -4, -2), not representative user.

i know reverse way , store identifiers keys , addresses' names values, i'm curious , wanted learn how force autocompleter tag show keys instead of map values. easy way not solution me.

i believe question has more jstl / ognl struts2 tags , find interesting couldn't find googling example on how this.

my autocompleter tag inside jsp

<sj:autocompleter          id="addresses"         name="selectedaddress"         list="addresseslist"         href="%{findaddresses}"         delay="50"         loadminimumcount="2"/>

that addresseslist hashmap inside action. tried endless combinations using listvalue , listkey properties, setting listkey = addresseslist.keyset() , things that, sadly none worked out.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
