Hi,
The behavior that you are seeing is an expected one. As i can understand, you have an HTML form element whose name is a fully qualified parameter & currently at runtime it is _piref1_41281_1_1.next_page If you carefully observe this, this name itself contains a period (dot).Hence when the browser tries to execute this, it thinks that _piref1_41281_1_1 is an object (which it isn't).
The whole issue is because there is a dot in the fully qualified name which has this format _piref<portletInstanceRefId>.<ParamName>
You could do the following to get it work. Use the following,
document.standinglist.elements["._piref1_41281_1_1.next_page"].value = "/htdocs/stand/standcancel.jsp?flag=flag";
Note however that this method call will not work on portal 3.0.9. when viewed using IE. This is due to IE's bizzare handling of this javascript call.
Since, you are using Portal 9.0.2, you should not face any issues.
Hope this helps.
