[Solved] data.Store problem

[fedelman]

Guys, I've got a data.Store like that:



var myds = new Ext.data.Store
(
{
proxy: new Ext.data.HttpProxy
(
{
url: 'http://foo.bar/list'
}
),
reader: new Ext.data.JsonReader
(
{
root: 'posts',
totalProperty: 'count',
id: 'id'
},
[
{name: 'title', mapping: 'title'},
{name: 'timestamp', mapping: 'timestamp'},
{name: 'post', mapping: 'post'}
]
),
remoteSort: true
}
);
myds.setDefaultSort('timestamp', 'desc');};
What happen if the target URL (http://foo.bar/list) not exists, timeout, return an invalid data or another fail option?


How can I catch this error and display in a Ext.MessageBox.alert()?

I use this ds in a grid.

Thanks,
Fede

How do I show the response body in the message box.



ds.on('loadexception', function(httpProxy, o , response) {
Ext.MessageBox.show({
title:'An Exception has occurred',
msg: 'The server has encountered a problem and is unable to retrieve your data.' + response,
buttons: Ext.Msg.OK
});
} );All I get is [object]

[mystix]

you'll need to inspect the response object via FireBug and pull out what you need from there.

yeah i'm looking at it but I don't understand how to read the response object in javascript (not an expert on this kinda thing)

I'm using monorail and setting the response to 500 (exception) and rendering the Exception.Message to the response body.

how do I just pick up whats in the response body and splat it to a messagebox

alert(response.responseText);

[TheNakedPirate]

thanks i'll give that a go

The solution I ended up with was this.

Thanks for the help



this.dataSource.on('loadexception', function(httpProxy, o , response) {
Ext.MessageBox.show({
title:'An Exception has occurred',
msg: 'The server has encountered a problem and is unable to retrieve your data.<br/><font color="red">' + response.responseText + '</font>',
buttons: Ext.Msg.OK
});
} );
