[Actionframework-users] Error in 0.94beta ?

[<bm...@ho...>]

hi, I have recently updated to the 0.94beta version and have found the
following problem:
I have an action that requires some parameters, so I put inside the <action>
node an input-variable in case there werent sent any parameter by the user,
like for example: <input-variable name="nDay" value="0" if="!$nDay">
With the older version it worked fine, but now I get that error:

Conversion error occurred when handling action '/' (request
type='http.get') - field: nDay:
org.actionframework.MissingParameterException: Parameter 'nDay' does not
exist (required by action '/'); nested exception is:
org.actionframework.MissingParameterException: Parameter 'nDay' not defined

Thx in advance
