Hi i get an exception from time to time (can’t reproduce) and don’t know what to do..

Here is the stacktrace:

I Guess somehow prettyfaces is involved in this:

at com.ocpsoft.pretty.faces.beans.ParameterInjector.injectPathParams(ParameterInjector.java:85) [prettyfaces-jsf2-3.3.3.jar:]
at com.ocpsoft.pretty.faces.beans.ParameterInjector.injectParameters(ParameterInjector.java:54) [prettyfaces-jsf2-3.3.3.jar:]
at com.ocpsoft.pretty.faces.event.PrettyPhaseListener.afterPhase(PrettyPhaseListener.java:102) [prettyfaces-jsf2-3.3.3.jar:]

I use:

JBoss AS 7.1
inbuilt
mojarra
JSF 2.1
CODI
prettyfaces

Edit:

I somehow managed to fix it (see my answer), but i dont understand how my fix works …

Sometimes this url is called (after all cookies were deleted or never existed):

http://.../firsat/655/something/;jsessionid=uNCQNxYxmmuQak6bcfpfZTG-.undefined

Why did the jsessionid get confused with my prettytime rule ? idk …

It will be very difficult to tell you what exactly is going wrong there, but I can help you to understand at which point in time it happens.

The PrettyFaces phase listener kicks in after the RESTORE_VIEW phase. At this stage PrettyFaces processes all query and path parameters. As the error happens during ParameterInjector.injectPathParams(), the problem is related to some path parameter.

Before the injection happens, PrettyFaces checks the type of the bean property to which the parameter is bound. PrettyFaces then checks if JSF has any converter registered for that type. According to the stacktrace the field seems to be an Integer because PrettyFaces calls the IntegerConverter. The converter is used to convert the value of the path parameter from the URL (which is a String) to the target type (which is an int).

The exception says, that the input string +O.undefined cannot be converted to an integer. So it looks like this string is part of the requested URL.

Take a look at this example. Let’s assume you have a mapping like this:

<url-mapping id="userDetails">
  <pattern value="/user/#{userBean.id}" />
  <view-id value="/faces/user-details.jsf" /> 
</url-mapping>

If for some reason someone requests the URL /user/+O.undefined, you would get exactly this exception. So I think you will have to find the reason why this is happening. Perhaps you will find a clue in the access logs?!?

BTW: You can also use regular expressions to make sure a mapping is only processed if the path parameter matches a certain expression. Something like this:

<url-mapping id="userDetails">
  <pattern value="/user/#{ /[0-9]+/ userBean.id }" />
  <view-id value="/faces/user-details.jsf" /> 
</url-mapping>

See this chapter in the PrettyFaces documentation for details.
