Updating template data extjs -


i making window panel holds tpl config , have passed config named recordref window component following, wish update tpl config data in recordref.

rowdblclick: function(view, record,element,rowindex,e,eopts){     var me = this;     ext.create('mywindow',{             recordref: record     }); }

my window looks this

ext.define('mywindow',{     extend: 'ext.window.window',     alias: 'widget.details',     controller: 'details',     ghost: false,     constrain: true,     title: 'details',     modal: true,     resizable: false,     autoscroll: true,     items: [         {             xtype: 'panel',             reference: 'infopanel',             items: [                 {                     xtype: 'panel',                     tpl: ['<p>name: {name}</p>',                           '<p>age: {age}</p>'],                     listeners: {                         render: 'updatetpl'                     }                 },                 ... other items ...             ]         }     ] });

and function updatetpl in window's controller looks like

updatetpl: function(panel, eopts){     var me = this;     var view = me.getview();     var record = view.recordref;     panel.update(record); }

this code leads error 

app.js?_dc=1502746390069:102863 uncaught typeerror: cannot set property 'innerhtml' of null @ constructor.overwrite (app.js?_dc=1502746390069:102863) @ constructor.overwrite (app.js?_dc=1502746390069:51335) @ constructor.update (app.js?_dc=1502746390069:65016) @ constructor.updatetpl (app.js?_dc=1502746390069:180214) @ constructor.fire (app.js?_dc=1502746390069:18721) @ constructor.dofireevent (app.js?_dc=1502746390069:19625) @ constructor.dofireevent (app.js?_dc=1502746390069:62695) @ constructor.prototype.dofireevent (app.js?_dc=1502746390069:52784) @ constructor.fireeventargs (app.js?_dc=1502746390069:19478) @ constructor.fireevent (app.js?_dc=1502746390069:19437)

what doing wrong here?

pass data object panels update function.

panel.update(record.getdata());

the update function expects htmlordata first parameter. well: 

panel.update({         name: record.get('name'),         age: record.get('age')     })

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
