Hard crash when attempting to write from Spreadsheet component

Flow
1

Hi,

I’m new to the component and just experimenting. I’m trying to edit and save a spreadsheet and get a hard crash when trying to write the spreadsheet.

Here’s the code (nothing special, I think)


@Override
public void buttonClick(ClickEvent event) {
try {
spreadsheet1.write(fileName);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});

fileName is the name used to open the spreadsheet originally.

I’m running this in Eclipse Luna, Java 1.6, Vaadin 7.5, Mac OSX, Tomcat 6. I get a popup saying that Bootstrap has quit unexpectedly. In the Eclipse console I get only:


Invalid memory access of location 0x10c609ca0 rip=0x102f3b65b

The file is an .xlsx with multiple sheets and some intricate formatting.

I’ve traced the crash as far as the bolded line below in POIXMLDocument


public POIXMLProperties getProperties() {
if(properties == null) {
try {

properties = new POIXMLProperties(pkg);

} catch (Exception e){
throw new POIXMLException(e);
}
}
return properties;
}

I’ll go back and try with a simpler spreadsheet, but I’d really like to know what’s going on here before I build up anything around the component.

Thanks,
Bill

I am facing the same problem can you please explain how did you solve it.

I was really, really disappointed not to have any support from Vaadin about this and more or less dropped the project. It’s been a while and I don’t remember much, but I found this code, which did work (though it’s ugly) as far as I recall.

            buttonSave.attach();
            buttonSave.addClickListener(new Button.ClickListener() {
                
                @Override
                public void buttonClick(ClickEvent event) {
                    try {
                        // Overwriting seems to be a problem -- delete it first
                        new File(fileName).delete();
                        spreadsheet1.write(fileName);
                    } catch (FileNotFoundException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    
                }
            });

        }
