Compliation problem

Question

hi,
experts yesterday i had no problem with codes.
this code given by vinod sir.
but now some are problem raised.
DCIteratorBinding dciter;
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
dciter = (DCIteratorBinding) bindings.get("CrmControlView1Iterator"); // your table iterator in the pagedef
CollectionModel model = (CollectionModel)CrmControl.getValue();
ViewObject vo = (ViewObject)model.getRowData();
Integer value = Integer.valueOf(vo.getCurrentRow().getAttribute("crmctrlProsNextId")) + 1;
vo.getCurrentRow().setAttribute("crmctrlProsNextId", value);
dciter.getDataControl().commitTransaction();
Error(36,58): cannot find method getValue()
Error(38,30): cannot find method valueOf(java.lang.Object)
Error(38,38): operator + cannot be applied to java.lang.Integer.valueOf,int
how to solve this?

hey,
DCIteratorBinding dciter;
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
dciter = (DCIteratorBinding) bindings.get("CrmControlView1Iterator");
Integer value = Integer.valueOf(dciter.getCurrentRow().getAttribute("crmctrlProsNextId").toString()) + 1; // Note the change to this line
dciter.getCurrentRow().setAttribute("crmctrlProsNextId", value);
dciter.getDataControl().commitTransaction();
i paste this code in my backing bean which is automatically created by jspx.
no problem. with this and am also clear with is.
n ur codes working fine and i got the exact output.am happy.
i found the following comment on your post.
Incase if your usecase is to increment the id by 1 on commit,
I suggest you to do it in model(probably in setter method of the attribtue in ViewRowImpl) instead of doing it in bean.
how can i do the following:
I suggest you to do it in model(probably in setter method of the attribtue in ViewRowImpl) // how can i do here that increment operation.
if you don mine can u tel using setter method of viewrowimpl to do that increment operation.
please.
