problem with getDescription()

[Anni]

hi again,

I got another problem. on the shop's home page I want to display the latest product with its description. getting the correct image and the product name is no problem. however, when I try to insert the product description via its getDescription()-method, only null is displayed. 
any idea, what went wrong? because it works perfectly on the product's details page ...

regards,
anni

Hi Anni,

When we get an array of products the description isn't fetched because it can be very long and so could stifle performance. In order to get it you have to call the getProduct() method of the engine passing it the language id and the product id. It will return one product including its description in the language that you specify.

hi julie,

thanks for the answer.
how would I do that in the jsp? something like: kkEng.getProduct(prodId, langID).getDescription()?

ok, I've tried that, but it seems to be wrong. now, that jsp isn't displayed anymore.

how do I do this correctly?

Hi Anni,

This is what you need to do :

if (prod.getDescription() == null ) {

   prod = kkEng.getEng().getProduct(kkEng.getSessionId(), prod.getId(), kkEng.getLangId());

        }

thanks works perfectly now!

ok, now I've encountered another problem. next to the latest product I plan to display the two next most recent ones. but my inserted code just prevents the page from being displayed (again) 

this is how I did it:

Code Select Expand


<%int i=0;%>
<td class="olderIssues">
    <logic:iterate id="prod" name="prodArray" length="3" type="com.konakart.appif.ProductIf">
<%if(i==0){%>
    <%i=1;%>
<%}else{%>
    <div>
<html:link page="/SelectProd.do" paramId="prodId" paramName="prod" paramProperty="id">
  <img src="images/<%=prod.getImage()%>" border="0" alt="<%=prod.getName()%>" title=" <%=prod.getName()%> " />
</html:link>
    </div>
<%}%>
    </logic:iterate>
</td>


do you know, why this is not showing up? I'm really confused as to why it doesn't work ...

Hi Anni,

The Tomcat log should give you some indication as to what is going wrong.

the tomcat log says:

Type mismatch: cannot convert from null to int

and

The operator == is undefined for the argument type(s) int, null



I have initialised "i", so there is no null!
getting more and more confused...

Hi Anni,

This is what you need to do :

if (prod.getDescription() == null ) {

   prod = kkEng.getEng().getProduct(kkEng.getSessionId(), prod.getId(), kkEng.getLangId());

        }
