Unable to get property get_current of undefined or null reference

Error Message:

Unable to get property 'get_current' of undefined or null reference.

Problem Description:

I wrote JavaScript function in my core .js file and calling from SharePoint list form.

SharePoint Form

Core .js file

In that function i.e."TravelRequestAdminDocumentReceived()" I am trying to get some information about the current context through the SharePoint JavaScript object model and am getting below error.

Solution:

This error is occurred because SP.js file not get loaded. To load SP.js file before our function we need to use following function

ExecuteOrDelayUntilScriptLoaded(TravelRequestAdminDocumentReceived, "sp.js"); 

Remark : After your custom function in ExecuteOrDelayUntilScriptLoaded don’t use brackets “()”.

Visio Services is unable to load

Error Message:

Visio Services is unable to load this Web Drawing because the Web Drawing URL web part setting is invalid. To resolve this issue, verify that the Web Drawing URL is properly formed and refers to an existing .VDW file.

Problem Description:

I found this error while adding visio webpart on SharePoint 2010 webpart page.

I got this error message because at the time of saving visio file  I kept by default extension i.e. “Drawing”.

Solution:

As shown in figure we need to change visio file extension as “Web Drawing”.

The Visio Web Drawing (*.VDW) is a new Visio file type that allows diagrams to be rendered in full fidelity in the browser using Visio Services on SharePoint 2010.
