why this happen? is this a know issue?

Answer 1

after more testing that issue i discovered that when i try to render report of type "Table" then the report is rendered fom rthe first time i pass/set the input values of the report, but when i use reports of type "chart" the report is not rendered from first time and it need a refresh and then manually entering the values for the input.
i am using the folloing version of JRC:
com.businessobjects.sdks_.jrc_.11.8.0_11.8.5.v1197
