kindly me subnodes list inside bom attributes
json file
[ { "subconfigid":"bac", "totalprice":"634.00", "bom":{ "ucid":"ucid", "type":"rootnode", "attributes":{ "visible":true, "price_status":"success" }, "subnodes":[ { "description":"enterprise shock rack", "ucid":"ucid" }, { "description":"svc", "ucid":"ucid" } ] }, "breakdown":{ "sv":550.0, "hw":6084.0 }, "currency":"usd" } ] gsonnodes.java

private list<subnodes> subnodes = new arraylist<subnodes>(); then getting error "expected string begin_array"
kindly me how can "subnodes" list
in bom.java
please add getter/setter method :
private list<subnodes> subnodes = new arraylist<subnodes>(); public list<subnodes> getsubnodes() { return subnodes; } public void setsubnodes(list<subnodes> subnodes) { this.subnodes = subnodes; } i have tried below .. working fine.
