Hi
When attempting to render a chart onto an SWT canvas, I get this error.
Ive added all the BIRT/ECore plugins as dependencies already do no avail.
Anyone know how to fix it? Any info is appreciated.

Hi Jason,
This explains a lot. (I assume that the 'ser' in your code is a
org.eclipse.birt.chart.model.Serializer instance. You see, the
serializer in the chart library is only intended to serialize and
de-serialize a chart file (created with a .chart extension). It is not
intended to handle de-serialization of a report.
The chart library is a part of BIRT designer but is also intended for
use outside of it. To enable users to save and load generated chart
files, the serializer has been provided.
If you intend to load a report design file, you will need to use the
appropriate API provided by the report engine.
I believe the appropriate API is SessionHandle.openDesign() that
returns a ReportDesignHandle you can use. Please check the Report Engine
API docs for more information.
Hope this helps.
Thanks,
Milind

Thanks. That certainly cleared some things up. However, is it not possible
then to use the designer to create and export a model for a chart? My intent
is to design the chart and serialize it to a file which is distributed with
a custom plugin. Later, this serialized file should be read in, data from
the datasource queried, and the result displayed on an swt widget. Ive seen
the example code for doing this on an SWT canvas, which is why I started
down this path. Is this possible at this point?

Hi Jason,
If by by 'designer' you mean the BIRT report designer, the answer is
simply 'No'...that is not possible. If on the other hand, you mean the
chart builder, there is no UI provided in the builder to save a chart
model to disk but there are ways to do this from the invoking class.
The chart builder UI is intended to be used as part of a separate
application that would handle the serialization / de-serialization of
the chart to disk if required. It is expected that if the chart library
is being used embedded in another application, the integrator would want
to embed the chart into the application's own document rather than store
it as a separate file.
It would be a fairly straightforward task to serialize the chart model
created by the builder. You could do this wherever you invoked the chart
builder from. You could use the 'getChart()' method to get the model and
serialize it using a Serializer instance.
Thanks,
Milind
