CRM 2011 : unable to cast object of type 'microsoft.xrm.sdk.entity' to type 'xrm.account'

To Solve it

Use enableProxyTypes method on your Organization Service proxy to fix it, here is the sample for generating organization service proxy properly:

OrganizationServiceProxy orgService = new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null);

 orgService.EnableProxyTypes();

 orgService.Authenticate(); 

 IOrganizationService _service = (IOrganizationService)orgService;

        if (attribute.getRequiredLevel() == "required") {
            if (attribute.getValue() == null) {
                if (valid) {

                }

CRM2011:Syntax error... /userdefined/edit.aspx?etc=

When I was using Visual Ribbon Editor, I added a group and a button to trigger a JavaScript function in a JavaScript Library, I was using CRM 2011 and rollup 12, I found this:

Issue:

If you upgraded to CRM 2011 rollup 12 already and use Visual Ribbon Editor to create button, and the action of  button is calling a JavaScript function in a JavaScript Library, you might get a JavaScript Syntax Error.

Solution:

Add $webresource: in front of you JavaScript library.

For examples:

in if you JavaScript library name is: myJavaScriptLibrary.js, then should specify like like this:

$webresource:myJavaScriptLibrary.js

OR

/WebResources/myJavascriptLibrary
