[Click] error in connecting a agnositc output port to a push input port

[albert]

Hi all,
when i use click elements to construt a simple router, i encounter
a weird problem.

I implemented a simple element named elename, which has a agnostic input
and at least one push output:
/const char *processing() const { return "a/h"; }/

In my configuration file, i connect the output of elename to the Strip
element as following:
...-> q1::Queue -> elename -> strip :: Strip(14) -> check ::
CheckIPHeader -> lookup::StaticIPLookup(..) -> ...

when i install this configuration with click-install, the following
problem occurs:
'strip :: Strip' pull output 0 connected to 'check :: CheckIPHeader'
push input 0


Anyway, when i install a similar configuration without elename element,
i can install it successfully.
Any advice?

Thanks!
