I have a process parameter listener which needs to execute a query based on the selected lines of an InfoWindow.
Currently the query is

StringBuilder sql = new StringBuilder("SELECT SUM(currencyConvert(Amount, C_Currency_ID, ?, sysdate, 0, AD_Client_ID, 0)) FROM XXA_TpaMovementLine WHERE XXA_TpaMovementLine_ID IN (")
.append(Env.getContext(Env.getCtx(), parameterPanel.getWindowNo(), "_IWInfoIDs_Selected")) // InfoPanel.ROW_ID_CTX_VARIABLE_NAME
.append(")");

Would be better to use it directly and have
StringBuilder sql = new StringBuilder("SELECT SUM(currencyConvert(Amount, C_Currency_ID, ?, sysdate, 0, AD_Client_ID, 0)) FROM XXA_TpaMovementLine WHERE XXA_TpaMovementLine_ID IN (")
.append(Env.getContext(Env.getCtx(), parameterPanel.getWindowNo(), InfoPanel.ROW_ID_CTX_VARIABLE_NAME))
.append(")");

but it requires to make it public.
