problems with reading and writing properties

Hi everyone,

I've made a basic component in Orocos (toolchain 2.2) with 1 property:
an eigen_matrix with the name Cf.
I'm using a typekit (see attachement). (with composeTypeImpl and
decomposeTypeImpl)
When I want to read/write my property to a cpf file, I encounter
following strange things (errorlog in attachment for more details):

*marshalling.writeProperty("Cf","nickstestjes.cpf")
**If nickstestjes.cpf doesn't exist yet =>It works
**If it exists=> ERROR: updateProperties ...

*marshalling.writeProperties("nickstestjes.cpf")
**If nickstestjes.cpf doesn't exist yet => ERROR: ...
**If it exists=> segmentation fault

*marshalling.readProperty("Cf","nickstestjes.cpf")
**If nickstestjes.cpf exists => calls decompose ?!, no error, but
doesn't work

*marshalling.readProperties("nickstestjes.cpf")
**If nickstestjes.cpf exist => it works

Thanks for looking in to this!

NIck

see attachment first mail (but for your convenience, I put it also below
this mail)

sometimes it gives:
marshalling.writeProperties("nickstestjes.cpf")

The command 'marshalling.writeProperties("nickstestjes.cpf")' caused a
std::exception: 'Bad DataSource assignment: incompatible types.' and
could not be completed.

but mostly it gives:
