Potential issue when two controls with similar features

Hi,

Just bit of a feedback which looks like a bug. Basically I imported a dataset custom control, bound it to the view in CRM and rendered it. Then I went into the source code and changed the namespace of this control and some other features like Description, etc. Imported the solution again.

Now I can see both custom controls inside CRM solution. However, the view to which the first control is bound seems confused. It does not show any control at all in the Customize View > Custom Controls area (not even the default Read Only view which is always there).

The solution was to delete the second control, unbind the first one from the view, delete first one, import the second control again and then finally bind the second to the view.

Cheers

I am noticing that when a faulty custom control somehow makes into CRM, it can cause the Add Control list of any view to become blank.

Steps to replicate
1. Goto any view and open properties
2. Choose Custom Controls > Add Control
3. You can see a list of of the default controls like Calendar, CardFeed, MailAppList, etc.

But when I have a faulty control (as explained in the previous step), this list does not appear at all and you rather see a message saying
There are no controls compatible with type (Grid) available.

I think there should be some kind of isolation in place to restrict the rogue control from bringing down the entire list.

Thanks Manny, that indeed is a bug. Would mind sharing the solution which can repro this, I was not able to repro.

Note that if the namespace and name of the control is changed, it becomes a brand new control at that time.

hi,

I am not sure about the exact steps. I did check the solution from Manny. Does not look like there are problems.

From the thread, it seems need to 2 solutions, first import some solution, then import another one then we see blank list

Now, to solve the issue, we could do either one of below:

1) Some one shares the right steps with 2 solutions to us, then we check and identify the bug

or if u r blocked

2) Some one just open a ticket and specify the repro steps. Our support engineer will reach to you, there might need a copy but we don't need data.

For option 2), we will provide DB mitigation if needed.

If you want privately sync, feel free to send email to us, my email is achen@microsoft.com
