problem with removing item from a paginated list
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

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!

Re: problem with removing item from a paginated list
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

Re: problem with removing item from a paginated list
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. Brandon On Fri, Jul 24, 2009 at 8:03 AM, Odelya YomTov ode...@jpost.com wrote: Hi!

Re: Questions regd ibatis best practices - need some help here
iBATIS 3 is in development and is not formally released yet. However, I can vouch that it is nearly function complete and pretty stable. You can check it out from Subversion and build it with Maven if you're interested in trying it. Here's the SVN link: http://svn.apache.org/repos/asf/ibatis/trunk/java/ibatis-3/ BTW - there's no published documentation yet - so look to the test cases to see how to use it.

Re: Questions regd ibatis best practices - need some help here
You don't need a parameter map for procedures in iBATIS2. This is
from the developers guide, page 30:
procedure id=“callProcedure” parameterClass=”com.mydomain.MyParameter”
{call MyProcedure (#parm1,jdbcType=INTEGER,mode=IN#,
#parm2,jdbcType=INTEGER,mode=IN#,
#parm3,jdbcType=DECIMAL,mode=OUT,numericScale=2#)}
/procedure
Similar in iBATIS3.
