Report Design Wizard in OpenErp

Hello ,

I created my report in PRD (Pentaho Report Designer 3.9.1-GA.16112).

I have 2 parameters : country_param and state_param that I added to my query.

When I run my report, It works fine .I select the first param (it'is a country drop-down list) which shows all countries.

The second parameter depends on the first. It shows all states.

For example, if I select Canada for the first parameter, the second shows all states in Canada exlcusively.

When I add my report in OpenErp, I get the same wizard : I reproduced the same example, but the state drop-down list dosen't work; it seems that the value chosen in the first drop-down list does not impact the second ; It show empty list.

Someone can help me to resolve this issue.
