hi guys,

I have a case at the Mondrian as follows,
I have two xaction Mondrian to be invoked through a html page
using the iframe as follows:

...
<body>
<div class='index-one'>
<iframe src="http://localhost:8080/pentaho/Pivot?...inance.xaction"
id="iframe2" scrolling="no" name="finance1" frameborder="0">
</iframe>
</div>
<div class='index-two'>
<iframe src="http://localhost:8080/pentaho/Pivot?...hboard.xaction"
id="iframe1" scrolling="no" name="finance2" frameborder="0">
</iframe>
</div>

</body>
...


initially normal, but after some time Refresh Browser, the error will always occur as follows:

23:23:48,042 ERROR [[Pivot]] Servlet.service() for servlet Pivot threw exception

java.lang.NullPointerException
at com.tonbeller.wcf.controller.
WcfController.request(WcfController.java
:71)
at org.apache.jsp.jsp.Pivot_jsp._
jspService(Pivot_jsp.java:198)

at javax.servlet.http.
HttpServlet.service(HttpServlet.java:803)
at org.apache.jasper.servlet.
JspServletWrapper.service(JspServletWrapper
.java:331)

why it happened like that, because they will happen if I using both the iframe page,
but when I plug only one iframe that calls a xaction only, no case of error

thanks for the help
