Hi, I'm fairly new to Orocos, my installation is not a part of ROS although I do have ROS installed on my computer.
I've looked at this topic: http://www.orocos.org/forum/orocos/orocos-users/error-type-array-did-not-provide-type-composition-function-i-need-one
but still nothing.
I'm attempting to configure a program with the following lines (located in a .cpf file):

The properties in question that are being modified are of std::vector<double>. The cpf and xml files have been reused from the previous 1.x version of the same code base.

as available data types.
What am I doing wrong? What might I be missing? (what part of orocos-toolchain might I be missing? noting my multiple failed attempts and work around)

Silly mistake, new error
The above errors have been fixed by adding a missing tag "name" and the corresponding Element# to the elements in the array struct.
However, a more confusing error is popping up.
Could not find Property int bufferSize in source
I've added
to the property file, and I've checked the source code and bufferSize is an int
this->provides()->addProperty("bufferSize", bufferSize).doc("buffer size");is in the constructor and bufferSize(30) is in the initialization list
this propertyfile is referenced by the main configuration file with
UpdateProperties does not give me an error, I've removed the line containing bufferSize, since it's been set in the code, but I'd still like to be able to configure this via an xml file...
PropertyFile (unlike UpdateProperties), the file must include all the properties in the component, now that I have bufferSize why is it still giving me the error?
This is occurring for more than one component.

I would recommend to use Toolchain v2.7 instead of v2.6

Is 2.7 considered stable ? Any formal release planned because the web
site only references 2.6.0 toolchain ?
