Comm.makeJsonRequest in SDK 1.2.6

In your other thread I asked about the size and complexity of the data you are getting back. Is this one in the sim or on a watch? If on a watch, which watch (fw Version too)

Data: {"status":"ok","data":{"user_id":778}}
Run on simulator
In 1.2.5 same code works correctly.

Is this the first time you app calls makeJsonRequest(), or were there earlier calls that worked? When it's started, is there:

for example,

call 1 that works
call 2 that works
and then
call 3 fails?

I develop my app on sdk 1.2.5 and Comm.makeJsonRequest() work fine without errors. Then I download sdk 1.2.6, change PATH to this bin directory and change path to sdk 1.2.6 in eclipse settings. After that Comm.makeJsonRequest() not work. I do not change my code. Only compile with new sdk.

Now I test it on other computer. In callback method I god:
data = null
responseCode = 302
But there is no redirect on this server!
