calculated columns in a pivot table
Hi list, This isnt so much a question, it's more that i'd like to hear your thoughts on the following. I'm making an webapp that shows a number of pivot tables or crosstables. Most repeaters are made for showing a list of objects, where each row is one object. While in a crosstab there is no connection between the values in one row except that they have the same y-coordinate. So to make things easier for myself and to have the webcomponents better reflect the nature of my data, i have used Loop() drawing on this: https://cwiki.apache.org/WICKET/how-to-work-with-excel-in-wicket-using-jexcel-api.html. The object that holds my data has methods to add a value (put(Pair coordinates, Number value)), to retrieve a value given the coordinates and to get the domain (= the rows and columns or distinct x and y values if you will). So now in addition to the raw data i want some tables to show totals, averages, and some other computed columns. I'm wondering what would be a good place to do this. Add them to the modelobject (the dataobject) in the panel that shows the table? Only add the extra columns to the table? I'm thinking that in the future i might give users the option to show or hide these computed columns. cheers Ivana - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
DatePicker NaN
Hi I have a problem with the DatePicker. It works fine if the input is a valid date or if the input is very wrong, for example: ''xxx". But when the input consists of numbers and but is not a valid date, the calendar is rendered with NaN in every field. I'm guessing this is a bug somewhere in the JS, or is it intentional? -- Ivana Cace Func.

Re: [Wicket-user] LoadableDetachableModels and Trees
Thats an interesting solution! I'm still using 1.2.6, and went 'up'. The Tree is on a Panel, the Panel gets a LDM and after some pre-processing builds the Tree using javax.swing.tree.TreeModel. I thought of doing the pre-processing in a class extending LDM and overwriting getObject, but part of the preprocessing is overwriting toString when creating TreeNodes and i want to have some flexibility here. The nice thing about the panel is that i add ajax-links for expanding and collapsing in the same panel. The panel is now updated with the rest of the page. James McLaughlin wrote: Hi Sean, Sure, if you have something in your XTreeModel that needs to be detached. But I was suggesting to make the TreeNode implement IDetachable. This way each TreeItem will detach its TreeNode when the request is over. Are you asking if you need to make your TreeModel detachable in order to have your TreeNodes detach? No, that is not necessary. best, jim On 8/1/07, Sean Sullivan <[EMAIL PROTECTED]> wrote: James, I am using Wicket 1.3's LinkTree class in my application. I built a custom tree model class that extends Swing's DefaultTreeModel: public class XTreeModel extends javax.swing.tree.DefaultTreeModel Should my class, XTreeModel, implement IDetachable? Sean On 8/1/07, James McLaughlin <[EMAIL PROTECTED]> wrote: For the trees in 1.3 (I haven't used 1.2.x in a long time), if your TreeNodes implement IDetachable, they wil be detached when the requestcycle completes. Then it is up to you to implement some logic in the methods you call to retrieve the user object (such as getUserObject()) from the TreeNode to check and perform reattachement. best, jim On 8/1/07, Ivana Cace <[EMAIL PROTECTED]> wrote: What do you want to use the model for?

It should be updated every submit. Is there a best practice for using a Tree with a LoadableDetachableModel? I now have a Tree that is updated on every mouseClick (in a node) and this seems a little too much. I would like to see a behaviour similar to ListView.
