Request Parameter names restricted?

Hi,

I have the impression that names used to identify request parameters are 
restricted.
I used a package name as the key for a request parameter, and got the 
following exception when trying to retrieve a request parameter:

java.lang.NumberFormatException: For input string: "epoline"
        at 
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
        at java.lang.Integer.parseInt(Integer.java:468)
        at java.lang.Integer.valueOf(Integer.java:574)
        at 
org.apache.pluto.portalImpl.core.PortalControlParameter.decodeRenderParamValues(PortalControlParameter.java:74)
        at 
org.apache.pluto.portalImpl.core.PortalControlParameter.getRenderParamValues(PortalControlParameter.java:292)
        at 
org.apache.pluto.portalImpl.servlet.ServletRequestImpl.getParameterMap(ServletRequestImpl.java:71)
        at 
org.apache.pluto.core.impl.PortletRequestImpl.getParameter(PortletRequestImpl.java:315)
<Snip>

After I removed the dots in the paremeter name, it all worked like a 
charm.

In my opinion using dots in request parameters should work fine, or am I 
wrong on this?

Regards,
Marcel

Hi Michael,

Thanx for your response.

In processAction you can try something like:

response.setRenderParameter("org.myorganisation.portlets.test.NextState", 
"org.myorganisation.portlets.test.SecondState");

If you set the parameter using the above name, btw the value is not the 
problem, there's no problem, but retrieving the parameter during the 
render phase gives the exception.

PS,
I think I solved the problem and sent the solution to the pluto-dev list, 
it can be found 
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=pluto-dev@jakarta.apache.org&msgNo=1523.
I do not know if this solution is correct, but in my situation it works.

Thanx

Marcel

Marcel, I can not reproduce the exceptions. Therefore I would really 
appreciate a small test case for further analysis.
