Hi,
I could explain you better the case, but at this time, it's difficult to
produce a sample program.
I setted up a single MapContext, with a simple DefaultMapLayer, all
inside a StreamingRenderer.
The FeatureSource for the Layer is a IndexedShapeFeatureSource, working
on a simple shape file.
Above the layer I applied a Style with a PolygonSymbolizer (representing
black lines)
and a TextSymbolizer to draw region texts.
Then I made a paint an obtain PNG image and
after that I moved the AreaOfInterest of the map end repaint to obtain a
second PNG image.
In the first and second image polygons moved correctly,
but labels was repainted 2 times in the second image, with an effect
like an echo.
It seems like a cache effect (something wrong on the TextSymbolizer).
The same happens doing zoomin/zoomout operations.
I hope that this is enough explicative, otherwise I will try to extract
a sample code from my project.
Thank you in advance.
Bye,
Manuele

I have noticed some problem switching to version 2.2-RC0.
For instance, after pan operations or zoom operations and
repainting the map, the labels (FeatureTypeStyle with
TextSymbolizers) doesn’t follow the layers. So I have a sort of
echo in all the labels!
Does anybody fall in this error?
Afraid not, I assume this error occurs in a styling pane widget?
This widget is not really supported in geotools 2.2, it makes use of
the legacy jar etc...
I was assuming the opposite (the Manuele uses the lite or streaming
renderer) because I have not done any change in J2D-renderer for a
while. While Renderer are you using Manuele?
Well if it is StreamingRenderer we have a bug to hunt down, what more
can you tell us? Have you tried a debugger? Lets set up an Issue in
Jira to track this (perhaps you could attach a sample program?)
Martin will apparently be working on it again for geotools 2.3 ...
And the work has begun!! :) For peoples interrested in J2D-renderer,
the work in underway in the ext/go module
(http://maven.geotools.fr/reports/go/index.html). It is a refactoring
of J2D-renderer as a GO-1 implementation (org.opengis.go.*
interfaces). In the process, I'm trying to fix many griefs posted
against J2D-renderer.
I never looked seriously to org.opengis.go.* interfaces before. But
now that the work has really begun, up to date I'm quite happy with
those GO-1 interfaces. They should help to improves greatly the
renderer since they are designed for interactivity for example.
Wow - 2.3 is really going to be the release where we catch up to
GeoAPI. Fun stuff, and glad your work is going well.
