Hi guys,

I am creating a Module that accepts some numbers and verifies them after submission, as a test to get going with the fantastic MojoPortal framework...

To simplify things and be able to learn, I followed the video tutorials and used the Guestbook tutorial files which made me create the different layers and classes, MSSQL database and scripts.  Visual Studio is compiling correctly on Windows 7...
To mention everything: I copied some c# en markup code and saved some GuestBook files with a different name to be able to base myself upon them and adapt everything to get it working... (as is done in the videos also)

When I go to the home page after a build and a setup on the site I get the error mentionned (way) below. 

I decided to also use also the comment control together with captcha in my module and thus am keeping these objects and code in my projects
The application hangs on the following line in Page_Load event in the LoadSettings() method because of a null reference of the edComment object: edComment.WebEditor.ToolBar = mojoPortal.Web.Editor.ToolBar.AnonymousUser;

When I remove all reference to these controls and code (that I don't really need for my tool's functionality), it gives a null reference error on the following line for the necessary btnSubmit object in the PopulateLabels() method: btnSubmit.Text b = ApplicationResources.SubmitButton;

It seems like it fails every time on an object I kept form the tutorial Guestbook files but don't know how to solve the issue.  The objects are defined in the designer file (designer.cs) of the ascx-control with their correct names.
I would like to prevent to have to restart the whole Module by adding this functionality manually.

Any tip or idea welcome!

Thanks
Pascal

Noticed while debugging,  a null object is passed in the overloaded (prefered) method 'SetupEditor' for the EditorControl and the method returns since this is null:  if (editor == null) return;

Any tip on where to look or what to check /  do welcome.... Thanks

Thanks Joe
Control is present and am inheriting from the correct base class. Have been comparing with the Guestbook project as confirmation...

Wanted to set a breakpoint on the GuestBook code and check what is happening there but this wasn't working anymore either - Guestbook didn't appear anymore on the page when going to the site
This made me wonder if my solution hasn't become corrupted : I am using my solution on 2 different pc's and was sycnhronising the folder with a backup tool from and to an external hard disk and this maybe the cause somehow....

Therefore I've setup a new development solution and added the guestbook and my own projects, did some tests: Guestbook is working fine as expected, My custom module is installed and can be selected to put on a new page - BUT is not appearing on the page.
Don't have the error anymore though...

Am a bit stuck as beginner, but wil keep on trying and experimenting and will post if I find a solution to my problem as a learning curve for others

Any tip on how to trouble shoot or on how to get to know the framework better, always welcome...  Thanks

You are right. It seems that my original error of null objects disappeared (or that code hasn't been hit yet) and that I'm having  problems on the button event handler now: 

In a habit I double clicked the button on the design page of the module control which generates a new event handler 'btnSubmit_Click1'. To be able to compile again I changed the method name to match the event handler name that worked before 'btnSubmit_Click'

Building the project worked fine, but the error was visible in the log of mojoportal site as you said. 

To solve the issue I removed all code and html related to the button and copied the one of Guestbook: not working, same error

Did a search on the wrong method name in the entire solution: 'btnSubmit_Click1': nothing found

Double clicked the button in GuestBook to see what happend with the handler:  Module didn't appear on the site page anymore aftwerwards --> this made me aware of my erroneous clicking of the button to create the eventhandler --> forgot that it is created /set in code

To solve this issue: I would need to know where this 'btnSubmit_Click1' is located?

I would maybe have given up already in other situations but mojoportal keeps me going :)

OK, thanks for reminding me of the basics of asp.net and markup...  Should have known that.

Still struggling though: isn't giving exception messages anymore on the SetupEditor but the edComment control is still null, instead the null exception comes on the line that adds the event handler on the button.  I think log4net suddenly catches the error (suddenly)

Moved up this method higher in the Oninit method: SiteUtils.SetupEditor(edComment); didn't help either !

Must still be missing or forgetting something...

Selecting the control with 'this.controlid' is working.  I suppose this means that all controls are present and correct names are used in code

Noticed that when I also use the 'this-object' of the page there's mentionned as base class while debugging: {ASP.name1app_name2withmoduleinit_ascx} where there's for the guestbook: {ASP.guestbook_guestbook_ascx} --> same control and featurename

Something tells me this is wrong and this is also the only difference I can find; In the codesmith definitions I must have most likely set these different names (to see the difference in functionality aftwerwards which is maybe blocking me now)

How can I fix this?  The  partial class name of my control already reflects the control name....

I used "SiteUtils.SetupEditor(this.edComment, true, Page);",  the correct overload before and it didn't work.

After my restart (new project) I indeed forgot to change this method with this overload. 
But am not sure this was the (only) problem --> I also removed the feature definition in the Admin menu and have run setup again ....AND...

IT WORKS :)

Thanks a million Joe!
