Hi Robert,
I tried to narrow it down by removing parts of the file. The first
culprit seems to be in the TextureAttribute. Removing it, will move the
error towards the end of the file.
I also counted the curly braces to see if the number of opening and
closing tags matches, which is true.
Unfortunately the non-working files are produced by some bigger
infrastructor (with a lot of visitors and an optimizer running over it)
so it is hard to reproduce.
Hi Sebastian,
I have just tried both files with svn/trunk version of the OSG. I see
both have 3.3.4 version and latest SOVersion marked in them so you've
made them recently.
Yes, the working version is built with osgconv, while the non-working
processed a bit more. This should not affect serialization IMHO, it
simply adds some more nodes.
Interestingly the error also occurs with the osgb format.
When I run the following I get:
$ osgviewer e_works.osgt
AsciiInputIterator::readProperty(): Unmatched property }, expecting Value
AsciiInputIterator::readProperty(): Unmatched property {, expecting
UniqueID
InputStream::readObject(): Unsupported wrapper class Drawables
All I get is blank window, and when I enable the stats by pressing 's'
I get odd resulting text suggesting an issue with what looks like a
blending issue.
When I run the second file I get:
$ osgviewer e_works.osgt
AsciiInputIterator::readProperty(): Unmatched property }, expecting Value
AsciiInputIterator::readProperty(): Unmatched property {, expecting
UniqueID
InputStream::readObject(): Unsupported wrapper class Drawables

I haven't begun investigating yet. Do you have an clues to what might
be amiss? Do you have the original file in a form that I could load
and have it work on screen. For instance exporting via .ive and .osg?
I will try to export to osg and ive if this helps.
Sorry, that I cannot give more insight since I'm not familiar with
serialization approach. The only thing I can do is to narrow it down to
the nodes which cause the problems.
Cheers
Sebastian
Thanks,
Robert.

Hi Robert, can you have look into the issue?
I've attached two versions of the file.
The working one is created by simply using osgconv. The
non-working version undergone some traversing by visitors,
optimizers etc.
Version is the current trunk.
I'll try to chase on my own to pinpoint the problem.
Cheers

I'm too deep in the shader work right now to pop up and take on
another topic, so will have to return to issues once this work is
wrapped up - should be in the next couple of days.
W.r.t serialization, work most of my testing I used .osgt and
.osgb so for a good range of uses it looks to be working fine but
just ran a quick test with your sign.osgt and it fails. I can't
dive into what might be wrong right now so can't provide an
specific suggestions as to what might be amiss.
Does the .osg format work OK for this data? If so could you post
a .osg version so that it can be compared.
W.r.t serializer changes since 3.2.x, the main changes have been
to make the serializers more flexible so that it enables the
better introspection capabilities required by scripting support.
In theory this changes shouldn't affect the reading/writing of
.osgt and .osgb files, but perhaps something has gone amiss
here. What it might be I can't say at all at this stage.
Robert.

Hi,
I've just created some osgb/osgt files and most of them
cannot be loaded anymore. They are failing with
InputStream::readObject(): Unsupported wrapper class ☺
for osgb files and
AsciiInputIterator::readProperty(): Unmatched property
Values, expecting UniqueID
for osgt.
I've attached the file in binary and text flavour which are
not working for me.
Can someone please check if they are behaving the same on
their machines?
@Robert: It seems something got broken with the serialization
since the 3.2.x versions.
