[CLOSED] RTE with new config property

[jchau]

I created an IconCombo class that inherits from ComboBox. *It has an extra IconClsField property. *After upgrade to v0.8, I am getting the following server error:

"Token PropertyName in state Property would result in an invalid JavaScript object."

** at Newtonsoft.Json.JsonWriter.AutoComplete(JsonToken tokenBeingWritten)
** at Newtonsoft.Json.JsonTextWriter.WritePropertyName(String name)
** at Coolite.Ext.Web.ClientConfig.WriteValue(String name, Object value) in C:\Program Files\Coolite\SVN\toolkit\Coolite.Ext.Web\Core\ClientConfig.cs:line 503
** at Coolite.Ext.Web.ClientConfig.ToExtConfig(PropertyInfo property, Object obj, ClientConfigAttribute attr, Object defaultValue) in C:\Program Files\Coolite\SVN\toolkit\Coolite.Ext.Web\Core\ClientConfig.cs:line 445
** at Coolite.Ext.Web.ClientConfig.Process(Object obj) in C:\Program Files\Coolite\SVN\toolkit\Coolite.Ext.Web\Core\ClientConfig.cs:line 169

The extra property:

** * * *<ClientConfig()> _
** * * *<Category("Config Options")> _
** * * *<DefaultValue("")> _
** * * *<Description("The underlying data icon to bind to this ComboBox.")> _
** * * *Public Property IconClsField() As String
** * * * * *Get
** * * * * * * *Return If(DirectCast(Me.ViewState("IconClsField"), String), "icon")
** * * * * *End Get
** * * * * *Set(ByVal value As String)
** * * * * * * *Me.ViewState("IconClsField") = value
** * * * * *End Set
** * * *End Property

[jchau]

*Fixed it. *There was a change in how Items collection was serialized to the client. *Had to make some changes to my IconComboBox class to handle that.

Hi Jacky,

Glad to hear you got it figured out.*


Please feel free to post details of the solution if you could... or what had changed between the releases.

I am having this exact same issue - is there any chance you could post some information about how you fixed it? this seems to be the only thing on google in relation to it...

I overrode the ItemsToStore property as follows:




Protected Overrides ReadOnly Property ItemsToStore() As String


Get


Dim sw = New IO.StringWriter


Dim jw = New Newtonsoft.Json.JsonTextWriter(sw)


Dim converter = New IconComboItemCollectionJsonConverter()


converter.WriteJson(jw, Me.IconItems)


Return sw.GetStringBuilder().ToString()


End Get


End Property

Sorry man - dont want to sound a bit spesh - but where does that property live?

[jchau]

It's in the base class I believe. Coolite.Ext.Web.ComboBox. You should be able to find it in the source code. Are you trying to create an IconCombo too?

[cvista]

Ah no, I'm using newtonsoft, castle and ext but not coolite - unfortunately.

[jchau]

Oh...my issue was specific to Coolite. Not sure if this applies to your issue.

[cvista]

I think it has to do with the custom converter - i'll have a look at that...
