Thanks in advance

Hi, now it generate the right code ...

Its a: "Now OK, later KO, Now OK, ..." intermittent error behavior ...

Hello Luca!

Please share public link (go Test- check Public- copy URL) and tell where do you get code generation error (you can send link to a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a).

Also provide more details such as what changes in builder do you make before it becomes wrong again.

I think is a decode/encode problem
I got a service url that work in the gui interface in tab test and is encoded:
precode
http://query.yahooapis.com/v1/public/yql?q=select%20%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.tmview.europa.eu%2Ftmview%2FbasicSearch.html%3Fq%3Deccolo%22%20and%20xpath%3D%22%2F%2F%5Bcontains(text()%2C%20'cacheKey')%5D%22&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys
/code/pre

this the decoded on just FYI
precode
http://query.yahooapis.com/v1/public/yql?q=select * from html where url="http://www.tmview.europa.eu/tmview/basicSearch.html?q={queryString}" and xpath="//*[contains(text(), 'cacheKey')]"&env=store://datatables.org/alltableswithkeys
/code/pre

but the service generated does not escape the "'" char correctly
precode class="javascript"
/*

• Services
  */

  var svcDef_getTMViewXML = new Appery.RestService({
  'url': 'http://query.yahooapis.com/v1/public/yql?q=select%20%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.tmview.europa.eu%2Ftmview%2FbasicSearch.html%3Fq%3D{queryString}%22%20and%20xpath%3D%22%2F%2F%5Bcontains(text()%2C%20'
  cacheKey ')%5D%22&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys',
  'dataType': 'xml',
  'type': 'get',
  });
  /code/pre

Luca, use this URL http://query.yahooapis.com/v1/public/yql instead.
The rest set up with Request parameters (you have q and env).

May be I do not explain the concept clearly so, in my opinion, the problem is the generation of the service; in fact the javascript object passed to "new Appery.RestService" do not escape correctly the ' char.
You can see this easily with a code highlighter editor (I have attached a picture showing that first piece of code wrong generated and the second using '' to encode correctly the string)
That's it.

Done!!

Yes, symbol ' is not allowed in url. If you need this symbol in url you should manually escape it with symbol \
For example
http://siteurl.com/?q=\'text\'

Sorry but I think that is just a work-around and not a solution; because in the gui in which I define the Service the string must be un-escaped otherwise the test do not work ... so is the code generator that have to insert the escape chars when it codes the service code.
