Property files get messed up in rtt 1.4.99?

Hi,

I have a component with a property file which contains the following:



The position Prop feedback gain for velocity resolved
control.

100
100
100
100
100
100

After I run my program, the contents of the property file are changed to:



The position Prop feedback gain for velocity resolved
control.

100
100
100
100
100
100
100
100
100
100
100
100

so for some reason, my property vector is expanded, even though I only _read
in_ the property (I am sure of this). Is this a bug?
I think it is related in some way to the "name" attribute.
When I remove all "name" attributes in the "simple" tags,
the vector is only expanded by one element.
There is still a "name" attribute but only in the "struct" tag. Obviously I
cannot delete that name attribute.

What to do about this? Is there an error in my property file? It used to be
fine in older versions. My "current solution" is to copy back the original
property files each time I restart the program.

Thanks!
Best regards,

Diederik

The name=... property for the 'array' type has been dropped. Each element's
value is now determined by the order in the file.

You should delete the six lines above

and keep these.

Normally, reading should not change the file. so you are calling the wrong
function or it is a bug.

Try my suggestion with nameless elements.

If I do this, the next time I run the program I get the following


The position Prop feedback gain for velocity resolved
control.

100
100
100
100
100
100
100

So then the array is expanded with one element (a simple) which does get a
name. It is worth noting that none of this happened in rtt 1.4.

Okay I was unclear here, I meant that there are no assignments happening, the
values and dimensions of the properties are not changed in my code.
But there is a writeProperties call when the component is shut down.

I did, see above.

Both cases are definately wrong. Can you submit a bug report and attach the
output of orocos.log with ORO_LOGLEVEL=7 ? Also could you specify with which
functions you are reading and writing the property file ?
