XPages Server Bug You Might Not Know About, But May Have Already Bit You.
Wed, Aug 25th 2010 4:28p Jeremy Hodge Ok, so this is an interesting tip. Some of you may have read my last post on my blog about a serious delay issue I've been having with an XPage application. Through some hard work with Nathan T Freeman (Mr NTF himself) and the XPages Team at IBM, namely Philippe Riand, Mike Kerrigan and more, we've discovered a bit of an interesting issue. The problem lies in DNS name resolution on your server. XPages uses "server" as a server name for some internal URLs to access resources within the NSF. We [read] Keywords: ibm

An Easy Way to Set the TAG of Computed Text to Aid in Semantic HTML Structures
Wed, Aug 25th 2010 5:44a Paul Hannan There's a new property added to the Computed Field control in 852 called 'tagName'. This started life as an enhancement request from fellow IBMer and XPager Thomas Gumz and this property allows the control to emit a tag for computed text, like h1, h2, h3 tags to aid in creating semantic HTML structures for documents (to help in search engine optimizations, etc).
It's pretty easy to use. Add or use any Computed Field control, , select the All Properties panel and in 'basics' you'll see the new p [read] Keywords: ldd

XPages Multi-level Category Filtering - categoryFilter enhancement in Notes Domino 852
Thu, Aug 19th 2010 9:14a Paul Hannan The multi-level category filter is a new enhancement in Notes Domino R852. It's an addition to the categoryFilter feature in the View data source that allows you to filter a view by the category and then the sub-category. It's a neat way for refining your view document collection even further than just by the main category.

We created two Java classes, one for the master record, Hello World, and one for the detail record, HelloCountry, set up HelloWorld as a managed bean, and wrote an XPage to work with Record set to display the detail and allow the user to interact with that detail.

Using Navigation Rules in Your XPages Application
Mon, Aug 9th 2010 10:13a Jeremy Hodge Another feature of JSF that has been surfaced in XPages is the ability to create "Navigation Rules" for your pages & application.
Navigation rules are a simple mapping of an identifier string to another XPage within your application, simplifying navigation.
For example, you can create a button that performs an action, and then based on that action, you can return the navigation rule's identifier to redirect your user to that page.

Quick Tip: Passing a Value from the client to the Server using XSP.PartialRefreshGet
Mon, Jun 28th 2010 12:55p Jeremy Hodge I make extensive use of the XSP object's partialRefreshGet and partialRefreshPost functions to invoke interactions with the Domino XSP server. It's generally accepted that a Get is faster than a Post because there is no data updating to do, no data to collect etc.
But sometimess, I need to send a single transient value up to the server to influence the returning results. You can do this on a get through the combination of a params object in the options object sent to the partialRefreshGet, and t [read] Keywords: domino

Resizing an XPage Control with DHTML
Sun, Jun 20th 2010 1:17p Peter Presnell From time to time there is a need to design an XPage in which one section needs to fill the remaining screen real estate. Setting width to 100% and height to 100% does not always produce the desired result, especially across multiple browsers. One solution to this need is to use DHTML to calculate the available height/width and assign the height/width to the appropriate components of the HTML. Because browsers can be resized we need to perform this calculation when the page is first loaded as [read] Keywords: ibm

Quick dojo.query tip for Cross Browser compatibility.
Wed, Jun 16th 2010 6:57p Jeremy Hodge One big client side plus to dojo in XPages is the dojo.query function that can find an HTML element using CSS selectors. For example to find a div tag with an ID attribute equal to "findMePlease", you can use the following code:
var myDiv = dojo.query('div[id="findMePlease"]')[0];
And you will get back the node you were looking for.

1. All items nodes that are going to be submitted to the server to be processed, updated, saved etc need to be within the Form element
