## Unable to get property ‘get_current’ of undefined or null reference in JSLink on list view

we need to filter list view items based on some conditions for which we need current context(sp.ClientContext). but we are getting undefined or null reference. we have also followed the solution provided by Vadim Gremyachev on Stack exchange

but as soon as the sp.js loads; list view also gets load. so whatever condition we want to apply to filter out list view items does not work as the required code starts working after list view loads.

Please suggest how we can solve this problem.

## Cloud Functions – CORS – Cannot read property ‘origin’ of undefined

I am trying to set up cors into my project but after installing the package I am getting error after I try to deploy to Firebase.

Error

Error: Error occurred while parsing your function triggers. TypeError: Cannot read property 'origin' of undefined 

My Code – index.js

const cors = require('cors')({   origin: true });

## Simple property of DFAs

Do you know if this simple property of a DFA is stated as a property (or theorem) in some Automata theory book (possibly with a particular name)?

Property: Given a DFA $$A = \{ Q, \Sigma, \delta, q_0, F \}$$, if $$w = uv$$ and the state of $$A$$ on input $$w$$, after scanning $$u$$ is $$q_i$$ (when the head is at the beginning of subword $$v$$); and $$A’ = \{ Q, \Sigma, \delta, q_i, F \}$$ then $$w \in L(A)$$ if and only if $$v \in L(A’)$$

## HREFLANG and different GSC property for every language

According to this article https://www.searchviu.com/en/hreflan…ntation-guide/,
it’s suggested to create a Google Search Console property for every language or country version of your website.

So, this means different properties for every /de/, /fr/ etc subdirectory

I wonder how this is going to affect the previous history of our website.
Suddenly all our Impressions and Clicks will be split among different properties, which complicates things.

Do you really think that there are more benefits of doing this that worth the trouble?

## Uncaught TypeError: Cannot set property ‘bootstrap’ of undefined

I’m receiving the following two errors, i’m unsure how to fix them. after doing some research this file has had issues before. The solutions did not solve my problem. Could this be a simple script load order?

Uncaught TypeError: Cannot set property ‘bootstrap’ of undefined (anonymous function) @ bootstrap.js?ny6rj2:13

## Question about one step in proof of mean value property

I took notes in class that $$\nabla u(x,y,z) \cdot \vec{n}=\partial u/\partial r$$, where $$\vec{n}$$ is the unit outward vector and $$r$$ is the radius of the ball centered at $$(x_0,y_0,z_0)$$.

How to get this result? Thanks!

## C# How to Prevent Accidentally Editing Backing Store of a Property

In C#, is there a way to not accidentally edit the backing store instead of the property?

(Assuming they are in the same class)

## Does the “Changeling” property count as an enhancement bonus?

The changeling property in the Magic Item Compendium p.31 names a flat price of 2000 gp. It does not say that it counts or costs as much as a +1 enhancement.

Does that mean that the property doesn’t count as an enhancement (and thus does not increase the price of the next enhancement and doesn’t count towards the limit)?

Or does it count as a +1 enhancement but always cost a flat 2000 gp?
