[Unexpected exception caught]

Why can't you revert? You need to use the same version of ireport ang jasperreports.

Try to find the jasperreports jar on apex an change it.

[iReport 3.7.2 Unknown hyperlink target 0]

Mistankenly I was using a .report made by de ireport 3.7.2. After use the same version for both ireport and jasperreport the problem has gone.

[iReport 3.7.2 Unknown hyperlink target 0]

Same error for me.

 

I'm trying to migrate from JR 3.1.2 to 3.5.1
