onclick event on and

[Aparna Tula]

I am relatively new to struts, so please do forgive me if this is a
silly question.

Here is my problem. 

Doesn't work:
        <html:image  
                srcKey="image.orders.buttonCancel" 
                altKey="altText.orders.buttonCancel" 
                onclick="history.back();"/>

But this works:
        <html:button property="cancel" onclick="history.back();">
                <bean:message key="button.cancel"/>
        </html:button>   

the onclick on <html:button> works fine, but the onclick on <html:image>
doesn't

Any ideas?

Thanks
Aparna
