How to reset form fields and rerender the form?

[jholusa]

Hi,

I'm stuck at pretty simple task: I have a search form where the search criteria are stored is SearchCriteriaSession bean, so it could be remembered and pre-filled. And I want to add reset button to that form that would: 

1) clear the criteria from bean, therefore call clearSearchCriteria() method of the bean
2) rerender the form, so the fields would be empty

Here's my code and I have no idea why it's not working:

search.xhtml

... 
<h:form id="criteriaForm">
 <div class="controls"> 
 <h:inputText type="text" id="testName" value="#handlingBean.criteria.testName}" /> 
 </div>

 //more input fields but with same format  

 <div class="form-actions"> 
 <r:commandButton action="#searchCriteriaSession.clearSearchCriteria}" value="Reset" render="@form :criteriaForm" /> 
 </div> 
</h:form> 
...

The searchCriteriaSession.clearSearchCriteria just clears criteria. When I debug it I see it correctly cleared. Even when I refresh the page the form clears, so the problem is that the render attribute is not working correctly, I guess.

Does anybody can please help me?

P.S.: I'm using RichFaces, this maven artifact:

<dependency> 
<groupId>org.richfaces.compat</groupId> 
<artifactId>richfaces-components-rich</artifactId> 
<version>4.5.0.Alpha2</version> 
</dependency>

hi,

I remember render list is comma seperate string. and in your case you only need @form. and your bean scope?

Hi liumin,

thanks for answer.

I have tried it even with render="@form", render=":criteriaForm", nothing worked. My bean is @SessionScoped.

Any other ideas?

hi,

when you debug, the getter is called?

[jholusa]

Hmm, that's weird.

I debugged it, put break points on the getter and clearSearchCriteria and this is what happens:

1) I enter some value into the field a do a search making the value stored in the bean.

2) Click reset

3) First break on getter with the old value

4) Break on clearSearchCriteria

5) Next two breaks on getter - but STILL with the value!

Something strange is going on. There must be a bug in my logic!!

Thanks for pointing me to the right direction, I will investigate it further and hopefully solve this.

Found the mistake in the bean's logic. Thank you very much for your answers! :-)

Hi again,

RichFaces 4.5 uses the a4j/rich prefixes, the "r" prefix is used by RF 5 (on top of which the 4.5 is built); command button is part of the richfaces-components-a4j artifact.

Buttons execute the whole form by default, if you don't want the values to be sent to the server add execute="@this" to the button.

The render list can be comma or space separated, you can also put in an Array, a List etc.
