problem with removing item from a paginated list

[Odelya YomTov <od...@jpost.com>]

Hi!
After deleting an item, I thought to delete it from my paginated list like
this:
yalkutService.deleteProduct(workingItemId);
ProductData tmpData;
for (int i = 0; i < productsList.size(); i++) {
	tmpData = (ProductData) productsList.get(i);
	if (String.valueOf(tmpData.getMakat()).equals(workingItemId)) {
		productsList.remove(i);
		break;
	}
}
}

But I get a JSP exception: 
ERROR [http-8080-Processor24] - Servlet.service() for servlet action threw
exception
javax.servlet.jsp.JspException: Exception accessing property lastPage for
bean products: java.util.ConcurrentModificationException
	at
org.apache.struts.taglib.logic.CompareTagBase.condition(CompareTagBase.java:
189)
	at
org.apache.struts.taglib.logic.NotEqualTag.condition(NotEqualTag.java:46)
	at
org.apache.struts.taglib.logic.ConditionalTagBase.doStartTag(ConditionalTagB
ase.j

how can I solve it?

Thanks!

Hi,

I dont think you should be removing from the list while iterating at the
same time.

Create a separate list (deleteProductList) and replace the
productList.remove() call with deleteProductList.add(tmpData).

After you finish iterating productList iterate over deleteProductList
calling the productList.remove() for each entry in there.

Thanks
Jon

Don't use the PaginatedList. It's deprecated. You should just use the
queryForList with the max and skip parameters. You get back a basic list.
Then you can do what you want with it. If your jsp problem still exists at
that point then it is something other than iBATIS.

Hi!

I tried your advice, but with no solution to my problem..

I problem is when writing the paginated list to the jsp, not in the JAVA code.

 

Thanks!

Also on the assumptions thats

= your ProductData class implements the equality and hashcode methods 

=  those methods use your 'id' field 

= You have a ProductData constructor that takes the id field

 

you should simply be able to do:

 

productList.remove(new ProductData(workingItemId));

 

no need to iterate.

Thanks

Jon

Also on the assumptions thats
= your ProductData class implements the equality and hashcode methods
=  those methods use your 'id' field
= You have a ProductData constructor that takes the id field

you should simply be able to do:

productList.remove(new ProductData(workingItemId));

no need to iterate.
Thanks
