Problem in Saving file - GEF

[vrushali babar]

Hi,

I have created a sample editor with flyout palette which can add radion button control to the editor. I could drag and drop the radio button from palatte to editor but can not save the file.
Error while saving -

java.io.NotSerializableException: org.eclipse.ui.views.properties.TextPropertyDescriptor
at java.io.ObjectOutputStream.writeObject0(Unknown Source)
at java.io.ObjectOutputStream.writeArray(Unknown Source)

I have implemented an abstract class with interfaces IPropertySource, Cloneable and Serializable.

Please advise me on this. Stuck since long.

Thanks in advance,
Vrushali.

You must have a reference to TextPropertyDescriptor somewhere.  Either re-factor your code so that what is being saved doesn't reference it or mark your field as "transient".

Hi Vrushali,

You should not be serializing UI classes when to save editor. Looks like you are writing editor for a declarative UI,you should be serializing your editor model (i will suggest xml) like below

<Shell xmlns="http://www.eclipse.org/xwt/presentation"
    xmlns:x="http://www.eclipse.org/xwt">
    <Shell.layout>
       <FillLayout/>
    </Shell.layout>
    <Button text="Hello, world!">
    </Button>
</Shell>

Check  http://wiki.eclipse.org/E4/XWT  and they have editor http://wiki.eclipse.org/E4/XWTDesigner .
