use commandLink, get value eq null in backing bean

[Jolie Lee]

Hi, i've a dataTable, and commandLink is one of the column. when i clicked on the link, i'm actually calling a method in the backing bean. and when i clicked the commandLink, a field, remark is required.

now my problem is, when i trying to retrieve remark in my backing bean, i kept getting NULL value. i won't have this problem is i used commandButton.

pls help..

here my commandLink:

  
<h:commandLink value="#{bundle.Common_Invalidate}" actionListener="#{rawMaterialVendorPricingBean.removePricingList}" 
 onmousedown="document.getElementById('rawmaterialform:autoscroll').value=getScrolling()" rendered="#{result.priceId != null && result.status == 1}"
 onmouseup="if (document.forms['rawmaterialform']['rawmaterialform:remark'].value == null || document.forms['rawmaterialform']['rawmaterialform:remark'].value == '')alert ('Please enter remark.');else if(confirm('#{bundle.Common_MsgInvalidate}'))this.click();else return false;" immediate="true"/>
 

and the code in my backing bean:

  
public void removePricingList(ActionEvent event){
        VendorMaster_Pricing vendorMaster_Pricing = (VendorMaster_Pricing)pricingTable.getRowData();
        System.out.println("remark="+this.remark);
       
        if(pricingList!=null && pricingList.size()>0){
if(vendorMaster_Pricing.getPriceId()==null)
pricingList.remove(vendorMaster_Pricing);
else {
vendorMaster_Pricing.setRemark(vendorMaster_Pricing.getRemark());
vendorMaster_Pricing.setStatus(new Byte("0"));
}
}
        setRemark(null);
    }

of cos, i do have the get and set method for my remark field.

is there anything wrong with my code? kindly advise. thks
