echo override at run time doesnt seem to be working

[Maryna Brodina]

Hello! When you change echo for REST service please ensure that data you're saving is the same format you specify in service settings (json, xml, jsonp). One more thing - when you do service execute() don't pass in this method empty object as a parameter.

Hi Greg,

Is there an error now? How can we reproduce it?

[greg keys]

test that app, login with username and password of test
then open your inspect console, click activities the console should say executing service when done click back and click activities again it should say loading cache and not proceed, you can see the error in the console

Hi Greg,

When and what data do you save in localStorage variable "cache_activities"?

I'd advise you to create a Generic service (custom JavaScript implementation) and there output the data you need.

That was originally the plan however when looking at documentation and getsatisfaction answers it seemed like the service echo should have been simpler , which now that we're going on a week of run around has proved to be the opposite.

Hi Greg,

Let's try. Do not hesitate to ask us if you have any questions.

ok so the Generic Service worked great thanks for the help.

Hello

I'm want to use response as echo for service.

I try following

on PageShow event of page I invoke service.
code
var user =localStorage.getItem('new_user');

Code: Select all

             if ( user == 'true'){ 
                 categories.__requestOptions.echo = ' '; 
                 localStorage.setItem('new_user','false'); 
             } 

             try { 
                 categories.execute({}) 
             } catch (ex) { 
                 console.log(ex.name + '  ' + ex.message); 
                 hideSpinner(); 
             }; 

/code

and on service onSucces I write following code.
code
'onSuccess': function(data) {
categories.__requestOptions.echo = JSON.stringify(data);
},
'onError': function(jqXHR, textStatus, errorThrown) {
alert("Error:can not fetch user projects.");
},
/code

but when I turn off internet and check the service , it show alert "Error:can not fetch user projects" means It's not use echo response when internet is not available.

Please help me.
Thanks

Hello! On error event run:
prealert(categories.requestOptions.echo);/pre
To see what you have in echo service use
precategories.requestOptions.echo = '';/pre instead precategories.__requestOptions.echo = ' ';/pre
there is an empty string insread space
