Exception when I add new News item

All Replies

I'm using v4.0.  I added 4 news items with no problem.  I noticed I had no way to set the publish date so they all got out of order from my original site's news.  So I updated the Created and Last Modified dates in the database.  The order is now the way I want it.

So I attempt to go add a new item and get the following exception:

ajaxToolkit:AutoCompleteExtender ('AjaxControlToolkit.AutoCompleteExtender'): cannot set attribute with name 'ShowOnlyCurrentWordInCompletionListItem' to 'true'


The server is Server 2008 if that helps.

Hello Chris Joyce,

About precise setting of the published date - you can use the Schedule Publish/Unpublish Dialog in the More Actions Menu.

About the js error that your receive - do you use some third party controls in Sitefinity or have you copied some additional assemblies in the bin folder. Is this happening on a fresh installation from Project Manager?

hi,

after upgrading my project to 4.1 i get this:

Server Error in '/IDS' Application.

Hi Andrei,

This sounds like some incompatibility of a customized ascx template and the .NET ASP.NET builder. Can you send us the markup of the template that you use - i guess it is customized database stored widget template for some of the public widgets- NewsView?

Nikolay,

You are right, it was a customized template to display a single news item. It worked perfectly in 4.0.

Once I have updated, it went wrong. I have messed about with the template since then and hence cannot
give you an exact copy. I am rebuilding it again from scratch with the latest internal build applied. Please
stay subscribed to this forum in case I have issues.

However, for now, one issue still remains. In the back-end template where news items are created, I get
some errors. See the attached image for details. All I did was to change the Label of the fields and the description.

Many thanks,
Andrei

Hello Andrei,
1) About the Resource problem. The error that you receive is related to a change in how we interpret localized labels in UI definitions. The way it was done was wrong, and now you should set resource key , rather than resource value. For example in a typical text field defintion:

var lastNameField = new TextFieldDefinitionElement(mainSection.Fields)
ID = "lastNameFieldControl",
DataFieldName = "Title",
DisplayMode = displayMode,
Title = Res.Get<SomeResources>().LastName,

should be changed to

var lastNameField = new TextFieldDefinitionElement(mainSection.Fields)
ID = "lastNameFieldControl",
DataFieldName = "Title",
DisplayMode = displayMode,
Title = "LastName",

If you don't need summary than you have to remove the code for the summary text field.
About hiding the url panel - generally  if your item needs to have a public url - it makes sense to keep this panel so users can customize the public url - if not you can probably use the CssClass property on the section level with some class that has display:none style.

Nikolay,

Thanks for your reply. I must say though, I did nothing in code. All I did was to go to "Custom Fields for news" and change the Author and the SourceName fields. I changed the Label and the Instructional text.That put it back as it was.

Now I am wondering if there is a way for me to change or add new resources that I could reference and get those labels and the instructional texts changed in the way that I want ???

Adding new fields seems to be working. The other challenge was to get the Single News Item template working, but if I get any issues with that, then I shall be posting the template.

Many thanks,
Andrei

Nikolay,

Hi again. Ok, I am getting the following error:

Server Error in '/IDS' Application.

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

  <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Nikolay,

Do not worry, I have sorted it out. I was adding my mark-up in the header it seems.
I have gone into Administration -> Interface Labels & Messages and changed all
the labels and descriptions from there and it looks fine now. 

Now, everything from The news side seems to work fine.

Many thanks,
Andrei

Last question,

Can I add code in some way to a single news item template. I want to note in the database
who has viewed an item. Since the page on which the item is viewed is auto-generated, I can not
drop any code on it. So the other way I was thinking was to add some code to the template
or a reference to a ASCX control which would be loaded and the code within it, executed.

Any thoughts / recommendations?

Many thanks,
Andrei
