Hi Hermod,
Thx for the reply.
The "Register" target is a copyPaste error, but even ommitting that
transition doesn't affect the stack-trace.
I haven't defined the context-param you mention and was unaware that it
was required, I thought the default setting was dialog?
Can you point me to info concerning this?

Hi
Just quickly looking at your dialog file, I notice that you have a target
"Register" that is not defined.
Looking at the code, the problem is that the web.xml context-param
Constants.DIALOG_PREFIX_PARAM is missing or ill defined. Have you defined
it?

Emne: Trouble with simple dialog
Hi,
I'm experimenting with the dialog manager and seem to have ommitted a
setting somewhere which is throwing an exception.
Basically I'm just hitting one page and after clicking a button I should
be brought to the next page, however this is not happening.
In the logs I see the following exception:

My dialog-config files looks like the following
<dialogs>
<dialog name="Create New Dialog" start="Input">
<transition outcome="start" target="Input"/>
<transition outcome="exit" target="Exit"/>
<view name="Input" viewId="/input.jsf" >
<transition outcome="next" target="Register"/>
</view>
<end name="Exit" viewId="/goodBye.jsf"/>
</dialog>
</dialogs>
& th epage itself contains
<h:form id="start">
<h:commandButton id="startDialog" action="dialog:Create New
Dialog" value="Create New Dialog >>" />
</h:form>
Currently I've no idea why it's not working :-((
Any help or links to examples would be much appreciated!!
Thx
/Colin
