hi

I am using <html:optionsCollection property='regions' label='state' value='code'/>

In ActionForm, I have variable

private Region[] regions; and setter and getter methods for this.

In the action class I am setting the form.setRegions(regions);

Initially when theform is loading, it is displaying regions.

But when I submit the page, it is going to the action class and setting the regions, but when the page is loading it is giving error that 'failed to obtain specified colleciton".

Could anybody tell me how to solve this?

Thanks
Praveena
