Hi jacopo,
i just implemented that in the new Accounting component, the only thing i had to do was: in the screen widget add the following lines: <set field="viewIndex" from-field="parameters.VIEW_INDEX" type="Integer"/> <set field="viewSize" from-field="parameters.VIEW_SIZE" type="Integer" default-value="50"/> the the form make sure the following parameters are there: paginate-target="/findInvoices" list-iterator-name="listIt" about the list iterator i am not completely sure, i use it with the new performFind service. The paginate-target should point back the the url used to called the screen. hope this helps...

Jacopo, This can be done in the same way in a bsh script as in the performFind service. Perhaps the easiest way to handle that is look at what it does in the FindServices.executeFind method, which is basically just return the EntityListIterator object. In the form widget you can use an EntityListIterator OR a List object, you just tell it which one by using different attribute on the form element in the form def XML. In your bsh script are you getting an EntityListIterator? -David On Sep 15, 2005, at 11:09 PM, Jacopo Cappellato wrote: > Hi Hans, > > yes, I know that it works in this way (i.e. using the performFind > in the form's action and then setting viewIndex and viewSize in the > screen's action); my problem is that I have some forms in which I > cannot use the performFind method (the list is prepared and passed > to the form by bsh script)... and for them the paginate links don't > work. > > Thanks for your feedback, > > Jacopo > > > Hans Bakker wrote: > >> Hi jacopo, >> i just implemented that in the new Accounting component, the only >> thing i had to do was: >> in the screen widget add the following lines: >> <set field="viewIndex" from- >> field="parameters.VIEW_INDEX" type="Integer"/> >> <set field="viewSize" from- >> field="parameters.VIEW_SIZE" type="Integer" default-value="50"/> >> the the form make sure the following parameters are there: >> paginate-target="/findInvoices" list-iterator-name="listIt" >> about the list iterator i am not completely sure, i use it with >> the new performFind service.

David,
thanks for the tips. No, in the bsh script (that is ManageQuotePrices.bsh) I get a list: however, I know that, to improve performance, I should use a list iterator, not a list, and I should manage pagination in the script (i.e. when retrieving data); however it would be nice to have pagination working in forms also over a complete list... I did a small change to the ModelField class to manage this (see attached patch): what do you think about it? Jacopo David E.

Hmmm... This is a good question. We probably should support pagination over a list, so I'll put this patch in. If the query result is large this still won't work because of memory constraints on the server, and it will be slow to pull the full list from the database. However, if a fairly sized list (say a few hundred elements) is in memory or cache, it still makes sense to page through it, so I'll throw this in. -David On Sep 16, 2005, at 12:27 AM, Jacopo Cappellato wrote: > David, > > thanks for the tips. > No, in the bsh script (that is ManageQuotePrices.bsh) I get a list: > however, I know that, to improve performance, I should use a list > iterator, not a list, and I should manage pagination in the script > (i.e. when retrieving data); however it would be nice to have > pagination working in forms also over a complete list... > > I did a small change to the ModelField class to manage this (see > attached patch): what do you think about it? > > Jacopo > > David E.
