[jira] [Created] (CB-519) FileReader.readAsText performs automatic
JSON.parse
FileReader.readAsText performs automatic JSON.parse
---------------------------------------------------
Key: CB-519
URL: https://issues.apache.org/jira/browse/CB-519
Project: Apache Callback
Issue Type: Bug
Components: WP7
Affects Versions: 1.6.1
Environment: VS.NET 2010 and WP7.1 emulator
Reporter: Alan Neveu
Assignee: Jesse MacFadyen
Priority: Minor
After upgrading from 1.5 I find that FileReader.readAsText takes the liberty of performing a JSON.parse if my file happens to be a stringified JSON object. While this seems like a nice addition, my app connects to an ASP.NET web service which uses Microsoft's serialization objects to serve the JSON to my app. Because of this I have had to roll my own JSON parse and stringify functions to deal with Microsoft's version of date serialization. I am able to work with the automatic JSON.parse by checking for typeof == "object" and if that is what FileReader.readAsText has returned then I go ahead and use my own JSON.stringify and JSON.parse and go along on my way. But I thought it was odd that this automatic JSON.parse would happen in the first place, so I submit this as a bug in case someone was doing some testing/debugging and accidentally left a line of code in place that should really not be there. I can live with it if it is intentional, but I think it would be more intuitive to not do automatic JSON operations that the function name does not indicate.

--------------------------------------------------------
I am also seeing a lot of this error while my code is just looping through fileEntries:
A first chance exception of type 'System.InvalidCastException' occurred in System.ServiceModel.Web.dll
I think there is some automatic attempts at JSON conversions taking place and some of my files are not JSON and so this error is being thrown. Looks like a similar thing is happening in another Jira case, CB-276 - https://issues.apache.org/jira/browse/CB-276
