For Input String: "" (Error: INF) error when open few Webi reports in XI R2

Hi All,

I am facing a an issue when trying to open/view latest instance of few webi reports with error For Input String: "" (Error INF). There are mutiple tabs involved on this issued reports. And also the reports deiplay a function name "function okCB() { var topf=getTopViewerFrameset(); if (topf!=null) topf.backToParent(); }".

I am able to run these report via 'modify' mode and all of them are completed the run successfully. IS this related with Java version issue? BO server java version is 1.6 and in my PC java version is 1.8.

BO version: BO XI R2
