Hi,

i have a msg package with a custom message like this:

MyStruct.msg
...
/* Content of MyStruct*/
HeaderStruct header
DataStruct data

using this msg type in different Nodes

Now i want to implement a srv using MyStruct.msg I modified my CmakeLists.txt of my service package with:

find_package(my_msgs REQUIRED)

and added to the package.xml

 <build_depend>my_msgs</build_depend>
 <exec_depend>my_msgs</exec_depend>

In the srv file i added

my_msgs/MyStruct data
---
float64 result
int64 calculation_time

but when building i always get the error

AttributeError: 'ServiceSpecification' object has no attribute 'base_type'

as soon as switching to this

float64 data
---
float64 result
int64 calculation_time

it works ... am i missing something ? Thanks!
