I'm currently developing an umbraco website and came across quite strange problem.
I need to display all pages that are type of event. I'm finding them all using this code:
new DynamicNode(UrlService.SiteRoot).Descendants(x => x.NodeTypeAlias == Constants.Events.DOC_TYPE_EVENT_PAGE).Items
This works very well but when I'm publishing the page through CMS and later executing this code again Property values are the same - as they are cached somewhere internally and publishing refresh the cache.
When I restart Application Pool I'm getting correct results untill...next publish.
What is even more interesting for me is that when I used Node and not DynamicNode ... all seems to be fine...
Please have a look at attached screenshot showing my watch in VS.
allEventsPages collection is the result of code above (collection of DynamicNodes). DateTime properties are showing 19 Feb 2012, but then I create new Node based on the ID of my dynamic node value of DateTime property is 18 Feb 2012...
I'm probably not aware of some internal caching for DynamicNodes... could you please advise how I can still use DynamicNodes and but avoid caching problem?
currently I'm doing this as a workaround but it's quite bad so would like to hear some better idea:
var allEventsPages = new DynamicNode(UrlService.SiteRoot).Descendants( x => x.NodeTypeAlias == Constants.Events.DOC_TYPE_EVENT_PAGE).Items. Select(x => new DynamicNode(new umbraco.NodeFactory.Node(x.Id))) .ToList();
Why are you using DynamicNode in this case? It's only useful if you use DynamicNode as a dynamic object. It's just a wrapper around the Node to support dynamic stuff, but your not using that here. Doesn't answer your question, but in this case I think it's better to use the Node or make your stuff dynamic.
To be honest I'm using DynamicNode because of the nice method - Descendants that takes lambda expression and allows me to query the whole content tree.
If you know equivalent of this method on the Node please let me know.
DynamicNode vs Node - different data in properties?

Well for the Node is always use uQuery from uComponents. Works very well :).

When i want to use uQuery to select all nodes from a specific type i know what to do.
But how do i select all underlying nodes of a specific type, starting from a specific node? I cannot find anything to do that.

Hi Tys,
You can use uQuery and Linq together, eg: (where 123 is the node id to start the search from, and 'docType' the node alias being searched for)
or use an XPath expression which is potentially much faster:
IEnumerable<Node> nodes = uQuery.GetNodesByXPath("//*[@id='123']//docType");HTH,
