JS error "Uncaught Error: Name conflict: contains" when no children template defined
websharperhtmlui.next

When I don't define any children template, I get the following JS error:

Uncaught Error: Name conflict: contains

Do I need to always define children template for the html?

Here is the code that I wrote:

1

//Client.fs
[<JavaScript>]
module Client =    
    type IndexTemplate = Templating.Template<"index.html">

    let rvTest = Var.Create "Hello"

    let Main =
        JQuery.Of("#main").Empty().Ignore

        IndexTemplate.Doc(Name = rvTest.View)
        |> Doc.RunById "main"

...

//index.html
<div id="main">
	<div>$!{Name}</div>
</div>

Version without error:

1

IndexTemplate.Main.Doc(Name = rvTest.View)

...

<div id="main" data-children-template="Main">
	<div>$!{Name}</div>
</div>
.

I can't seem to reproduce your issue; both versions work for me. Can you make sure that you are using compatible (eg. the latest) versions of WebSharper and WebSharper.UI.Next, and that your browser doesn't use a cached version of either?

It build, run and works as expected. But in the developer console on Chrome/Mozilla, I get the following error and warning:

1

3

Warning: Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.

Error: Uncaught Error: Name conflict: contains

Introducing a data-children-template remove both error and warning.

My version of WebSharper and UI.Next:

  • WebSharper 3.4.9.188
  • WebSharper.UI.Next 3.4.9.157

I can confirm this using:

  • WebSharper 3.6.10.320
  • WebSharper.UI.Next 3.6.8.204

The following works:

1
2
3

<div id="main" data-children-template="Main">
        <div data-hole="Content"/>
</div>

This doesn't:

1
2

<div id="main" data-hole="Content">
</div>

An interesting side effect is that everything seems to work fine, despite the warning and the error, but KendoUI starts behaving erratically in a non-deterministic manner. I spent hours trying to understand what was wrong.
