Guys these days the Pakis are WHINING a lot about the JF 17
There is no good news at all about The BLOCK 2 which was to arrive in 2012
The feeling that you get is that Right now Pakis consider the JF 17 to be " Less Than USELESS "
It is meant to replace their old Mirage III aircraft. Perhaps the F-7 in some roles too. So, I don't see how it is less than useless for PAF.
The JF-17 Block 1 and the Block 2 are equivalents of the current version of LCA, with LCA being more advanced. The Block 3 may very well be an equivalent to the LCA Mk2, but we don't know that for sure.
The way the JF-17 is today, it is inferior to our old Mirage-2000s and even their old F-16 Block 20s primarily in terms of electronics.
Anyway, what makes you think they are whining? Last I heard, the aircraft is being displayed for export, which is a good indicator of it's progression. I haven't heard about anything that says they are not happy with the JF-17.
