    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?
