Overwritten TypeInfo for standard types?

[meyerj]

Some standard types from the RTT typekit (bool, int, float, double etc.) do not print anymore in the TaskBrowser after a typekit generated by typegen has been imported.

Example:

Deployer [S]> var bool b1
 = false               

Deployer [S]> var int i1
 = 0                   

Deployer [S]> import("foo")

The typekit is the default typekit generated with orocreate-pkg, where the struct FooData only contains a vector of doubles. I am testing with the current toolchain-2.8 branches of all toolchain repositories.

@psoetens and I looked into this problem on Wednesday. The printing problem has been fixed in orocos-toolchain/rtt@a4659bb and orocos-toolchain/rtt@8cc95bc. The reason why the values were not printed is that orogen installs the typekit with a TemplateTypeInfo<T, use_stream> with the use_stream parameter set to its default value false and without the patches in rtt the stream factory was therefore overwritten, even if another typekit provides streaming operators.

However, that still does not explain why the typekit generated with the toolchain-2.8 branch (which is based on commit b0c55a1 in the master branch) registers new TypeInfos for the primitive types /bool, /double and so on. With the latest revision in master merged into toolchain-2.8 (v2.8.0-rc1) the result is different and the typekit only registers the /FooData and /std/vector</double> types, as expected.

There seems to be a difference depending on whether RTT has been compiled with scripting enabled or disabled.
