java - Primefaces Wizard does not proceed with selectOneMenu -


the wizard doesn't proceed next tab when use value="#{wizard.filial.numfilial}". but, works fine when use value="#{wizard.intfilial}". can me?

<!--xhtml--> <h:selectonemenu id="fieldfilial" title="filial" value="#{wizard.filial.numfilial}" required="true" label="filial*" >     <f:selectitem itemlabel="selecione" />     <f:selectitems value="#{commons.filiais}"  var="cfilial"                                itemvalue="#{cfilial.numfilial}" itemlabel="#{cfilial.descricao} "/> </h:selectonemenu>

wizard.java

    @managedbean     @sessionscoped     public class wizard{         private filial filial;         private int intfilial;         <getters/setters> }    **commons.java**      @managedbean     @sessionscoped     public class commons{         private list<filial> filiais;         <getters/setters> }  <!--filial--> public class filial implements comparable<filial>, serializable {     private int numfilial;     private string descricao;     <getters/setters>

you need instantiate filial object because need instance of filial type object contains numfilial.

try 

private filial filial = new filial();

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!
