CRM 2011 – error using Xrm.Utility.OpenEntityForm

I was fixing some code where the code passes a field to a form and then opens it using the excellent Xrm.Utility.openEntityForm

I added a new parameter, parameter_2. This was going to pass the name of a field I wanted to use

this.SelectCustomer = function () {

/// <summary>

/// Passes customer field values into the customer search screen for a user to create / search

/// for their workshop entry

/// </summary>

var parameters = {};

parameters[ “paramater_1”] = “name”;

parameters[ “paramater_2”] = “hosk_searchfield”;

Xrm.Utility.openEntityForm( “Hosk_Search”, null, parameters);

};

I wanted to add one more field but when I added a new field, the form didn’t open and I just got an error. A generic, which doesn’t tell you anything, I have been getting quite a few of these errors the last couple of weeks

I tried to debug the javascript onload but it wasn’t even being called.

I took away the new field and it worked.

FRUSTRATTTTING

calm down, be logical, engage brain.

I started with the SDK/documentation, lets see what should happen

http://msdn.microsoft.com/en-gb/library/jj602956.aspx#BKMK_OpenEntityForm

lets look at the parameters section

parameters: Type: Object

Optional: A dictionary object that passes extra query string parameters to the form. Invalid query string parameters will cause an error. Valid extra query string parameters are:

Form id: To set the id value of the main form to use when more than one form is available. The parameter is formid.
Default field ids: To set default values for a new record form. For more information, see Set field values using parameters passed to a form.
The navbar and cmdbar parameters described in Query String Parameters for the Main.aspx Page.
Custom query string parameters: A form can be configured to accept custom query string parameters. For more information, see Configure a form to accept custom querystring parameters.
