Dynamic XML issue
This one is driving me mad, so I am hoping someone can help!!

I have a "Related Links" property on my page, which links to several other pages in the site.

I loop though each one with
```
@foreach (var item in pageModel.carouselItems.BaseElement.Elements("link"))
{
  dynamic carouselItem = new DynamicNode(@item.Attribute("link").Value);
}
```
Each, "carouselItem" has got various properties, but the one I am having issues with is a "URL Picker", property name "captionUrl" (from Ucomponents).

If I output "carouselItem.captionUrl", I get "umbraco.MacroEngines.DynamicXml"

But, if I try "carouselItem.captionUrl.url", I get an error "'string' does not contain a definition for 'url'"

@item.Attribute("link").Value is pushing out ints, one of which is "1072", so I tried the following code:
```
        int number = 1072;
        dynamic testNode = new DynamicNode(number);
        <div> @testNode.captionUrl.url</div>
```
The above works fine, and outputs the URL as expected.

So, I tried setting an int value to @item.Attribute("link").Value. The following code shows that it is being set correctly as an int:
```
        int number2 = int.Parse(@item.Attribute("link").Value.ToString());
        <div>Number: @number2 Type: @number2.GetType()</div>
```
The output of the above is:

Number: 1072 Type: System.Int32

So, I tried combining the above:
```
        int number3 = int.Parse(@item.Attribute("link").Value.ToString());
        dynamic testNode2 = new DynamicNode(number3);
        <div> @testNode2.captionUrl.url</div>
```
But, the above code gives me the same error, I get an error "'string' does not contain a definition for 'url'"

I just don't get it, if I change the code to the following:
```
        int number3 = 1072;
        dynamic testNode2 = new DynamicNode(number3);
        <div> @testNode2.captionUrl.url</div>
```
It works without error, but as soon as I dynamically set the nodeId, if errors!!

Anyone got any suggestions?

Thanks

Hmm that is strange. What version of Umbraco are you using? DynamicXml has been changed a couple of times.

I am using version 4.7.1, which is one down from the very latest I beleive. (which is 4.7.1.1 if I am not mistaken)

Cheers

Could you please upgrade to 4.7.1.1 to see if that fixed it? It's a patch release so you can just update /bin, /umbraco and /umbraco_client

OK, I updated, but I am still getting an error.

It now doesn't tell me what the error is. It just says "Error loading MacroEngine script (file: Carousel.cshtml)"

That is annoying in it itself, as I can't now easily debug macro scripts!

If you have debugging enabled you can add ?umbDebugShowTrace=true to the url of your page to show the trace which will show the error.

OK, I can confirm that it is the same error was before:

I am not sure why it saying 'string' does not contain, as it should be dynamic XML at this point?

I have found a work around that means I can continue, but I think there may be a bug somewhere here, as I can't see why the above methods shouldn't work.

The following however works for me:
```
        DynamicNode xmlNode = new DynamicNode(int.Parse(@item.Attribute("link").Value.ToString()));
        dynamic urlXml = new DynamicXml("" + xmlNode.GetProperty("captionUrl").Value.Replace("-", "") + "");
```
I then have to check to see if there are any decendents, and output the result
```
@if (urlXml.Descendants().Count > 0)
{
```
@urlXml.Descendants()[0].url
```
} 
```
Note, I have to wrap the XML into root nodes, as the URL Picker doesn't have a root, and I also needed to replace properties that had "-" in them, as these were not accessible with the razer syntax

Hmm I see you are replacing the stripe (-). This is a bug which should have been fixed in Umbraco 4.7.1 http://umbraco.codeplex.com/workitem/30290

Might also be related to this: http://umbraco.codeplex.com/workitem/30680

Not sure if this info is helpful.

Right, issue solved..

I resaved the pages that were added to the releated link collection, and the error went away.

I am only guessing that it hadn't saved correctly to the database?
