Clear function not working properly

Hi All,

 

I want to clear two picklist values & one textfield value on click event of command link.

 

I have used actionFunction to call controllers method to clear the fields.

 

But whenever i click clear link on VF page, values vanish for 1-2 sec & again previous values are set in picklists as well as textfield.

 

I want to implement it through Apex only.

 

Can anybody tell me possible reason for this??

 

Thanks

Sachin.

Why havent u used the action property of the command link to call the controller method ? Just use the action and rerender your field section. 
SachinSankadSachinSankad

Hi swatkat,

 

Thank you for your reply.

 

As i want to clear row by passing it's index from VF page, I didn't use action property of the commandlink.

 

So i need to use actionfunction with param tag passing index to it & using same in controller's method.

 

Do you have any solution for this??

 

Thanks,

Sachin.

You can use apex param within the command link tag as well. Like this :

 

<apex:commandLink id="commandLink" action="{!displayName}" value="Show my name">
<apex:param name="Name" value="myName"/>
</apex:commandLink>

Create a variable to hold the index in controller. User aprx;param tag and bind that variable using addignTo attribute.
Now in action method, get property from index variable and clear it.
listVariable[Integer.valueOf(index_variable)].PicklistField__c = null;
listVariable[Integer.valueOf(index_variable)].TextField__c = null;

Rerender your section

Hi Bhawani,

 

Thanks for your solution.

 

I tried it but it's not working for me.

 

I am using inner class. Here by I am pasting my clear function & inner class as well.

 

Clear function :- 

 

public void clear()
{
System.debug('>>>>>>>>>>>>>>>In Clear<<<<<<<<<<<<<<<<<');
Integer indexCount = Integer.valueOf(ApexPages.currentPage().getParameters().get('index'));
//clearmap=new map<string,string>();
System.debug('>>>>>>>>>>>>>>>>Size of list<<<<<<<<<<<<<<<<<'+lstInner.size());
for(innerClass clearobj:lstInner)
{
System.debug('****************In For loop of clear function******************');
System.debug('>>>>>>>>>>>>Value of recCount<<<<<<<<<<<<'+clearobj.recCount);

System.debug('>>>>>>>>>>>>Value of indexCount<<<<<<<<<<<<'+indexCount);
if(indexCount == clearobj.recCount)
{
System.debug('================In if loop of clear function================');
//clearmap.put(clearobj.field,clearobj.value);
//fieldopermap.put(clearobj.field,clearobj.operator);

System.debug('=======Field before clearing======='+clearobj.field);
clearobj.field='--None--';
System.debug('=======Field after clearing======='+clearobj.field);
System.debug('=======Operator before clearing======'+clearobj.operator);
clearobj.operator='';
System.debug('=======Operator after clearing======'+clearobj.operator);
System.debug('=======Value before clearing======='+clearobj.value);
clearobj.value='';
System.debug('=======Value after clearing======='+clearobj.value);
}
}
}

 

Inner Class :-

public class innerClass
{
/*recCount acts as a index for a row. This will be helpful to identify the row to be deleted */
public Integer recCount{get;set;}
public string field;
public string operator;
public string value;
public list<SelectOption> supportedoperator{get;set;}
public String getfield()
{
return field;
}

public void setfield(String new1)
{
field=new1;
//operaterlist.add(new1);
// system.debug('operaterlist<<<<<<<<<<<<<'+operaterlist);
}

public String getoperator()
{
return operator;
}

public void setoperator(String new2)
{
operator=new2;
// system.debug('selected field list<<<<<<<<<<<<<'+SelectedFieldlist);
}

public String getvalue()
{
return value;
}

public void setvalue(String new3)
{
value=new3;
// Valuelist.add(new3);
}

/*Inner Class Constructor*/
public innerClass(Integer intCount)
{
system.debug('<<<<<<<<<inside inner class construnctor<<<<<<<<<<');
recCount = intCount;
}/*End Inner class Constructor*/
}/*End inner Class*/

 

VF Page :-

<apex:page controller="GDCDelete" sidebar="false">
<apex:form id="formId">
<apex:actionFunction name="ObjectFileds" action="{!ObjectFields}" reRender="block"/>
<apex:actionFunction name="oper" action="{!op}" rerender="block">

</td>

<apex:param name="rowToBeDeleted" value="{!e1.recCount}" assignTo="{!selectedRowIndex}" ></apex:param>
</apex:commandButton>
</td>

<td>
<apex:commandlink value="Clear" onclick="clear1('{!e1.recCount}');" reRender="block" />
</td>

</tr>
</apex:repeat>
</table>

</apex:pageblock>

</apex:form>

</apex:page>

 

Please help to solve this issue.

You doesnt seem to be have used to assignTo with params in ur code

 

<apex:actionFunction name="clear1" action="{!clear}" rerender="formId">
         <apex:param name="index" value="" assignTo="{!variableName}"/>
      </apex:actionFunction>
