java - Freemarker, Maps and Mongo. Getting a value out a nested structure -

-

i have mongo database , making small web application display values database. i'm having little problem getting value nested structure.

the database structure have is:

{       "_id": objectid("4e244ddcb1633b25c38f2155"),     "id": "2173",     "type": "p",     "title": "test title",      "tag": {       "0": {       "_id": objectid("4e244ddcb1633b25c38f1fc1"),       "name": "education",       "id": "6"  } }   }

what is, database database , put in map , map put several other maps 1 map (root) , put .ftl page. can read value in .ftl like: ${root.title} ofcourse print 'test title' in above example.

i value of name in tage can print 'education'

i don't know how this. ideas.

you can access value using freemarker's built-in's hashes. similar below:

<#assign tagkeys = root.tag?keys> <#list tagkeys tagkey>     ${root.tag[tagkey].name} </#list>

i have not tested yet speaking should work. might want read previous answers on so:

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
