bugfix for dead loop

[lepture]

if tpl is undefined, it will loop forever.

Where is the test case that proves this is a problem?

[lepture]

it's obviously. you set root as an array, and you don't have the template in both, it will loop forever.

Actually you can't write a test case, coz it's a dead loop, just think about it. when i doing my own project, it stopped there, and I have to add some log to find out what's going on.

This need not test case, just proper mind. Besides Iam on my phone.

It's obviously just a mistaken by @nka11

Hi,

@lepture you'r right, it's a beginner's mistake ;)

But @paularmstrong is right, a test is welcome. It should not fail with your patch. If the test has to fail (without your patch, it will hang the test suite)

@lepture I have to thank you a lot, with this fix i can now continue a stalled dev beacause of this bug.
