jsf 2 - JSF2 ui:repeat inputText wont re-render on first try -


i have ui repeat contains inputtext , command button pairs. button changes value inputtext displays , re-renders it. on first button click changes value not re-render on screen. second click same re-renders control. onevent triggers 3 status events fine. nothing shows in logs either. problem seems server side i'm using default faces setup netbeans 7.3.1.

the below code display 4 lines of inputvalue , buttons. first works fine (its outside of ui:repeat. 3 below require 2 clicks.

testbean.java

@managedbean @viewscoped public class testbean implements serializable {     private myobject nc;     private list<myobject> list;      public testbean() {         nc = null;         list = new arraylist<myobject>();     }      public myobject getnc() {         return nc;     }      public void setnc(myobject nc) {         this.nc = nc;     }      public list<myobject> getlist() {         return list;     }      public void setlist(list<myobject> list) {         this.list = list;     }      @postconstruct     public void oninit() {         myobject nc1 = new myobject();         nc1.settext("1");         list.add(nc1);         myobject nc2 = new myobject();         nc2.settext("2");         list.add(nc2);         myobject nc3 = new myobject();         nc3.settext("3");         list.add(nc3);          myobject nc0 = new myobject();         nc0.settext("0");         nc = nc0;     } }

myobject.java

public class myobject implements serializable {     public string text;      public myobject() {         this.text = "";     }      public string gettext() {         return text;     }      public void settext(string text) {         this.text = text;     }      public void testmethod() {         text = "hey";     } }

index.xhtml

i figured out. once changed .testmethod() .testmethod(ajaxbehaviorevent ae) works on first click. apparently treated differently jsf. hope else can learn mistake.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
