This is my first question. I have some doubts about one trouble. I saw that it could be there a duplicate question, but i'll try anyways.

My vf page code is below:

<apex:commandButton value="Cancelar" action="{!cancelar}" />

And the controller code is:

 public PageReference cancelar(){
    PageReference pf = new PageReference('/'+this.opp.Id);
    pf.setRedirect(true);
    return pf;
 }

Then when i try to click on it, an inputField required error is displayed: "Must write a value" or something like that. I could read some about apex:ActionRegion tags to split up the form into various groups of fields with their associated actions.

My inputFields within apex:form and apex:pageBlock are below:

 <apex:inputField value="{!oli.serviceDate}" label="" required="true" />

Thanks in advance, any help to handle this situacion will be helpful.
