Hi,

When I have named a variable and then later change the name (sometimes) it crashes the IDE.

Hi ,

I won’t be behind that computer again for a few days. I will try to replicate it on an other one.
(and send you the logs ASAP)

Yes; it was a clean project with the starter content. I added a string var to the Level BP. Changed the name a few times in the box above the box where you set the type.

Hi ,

Does this happen in a clean project with no additional content? Further, could you please post your logs from the crach, which can be found in the folder /PROJECTNAME/saved/logs/? Thank you!

Hi ,

Tried to reproduce it on an other computer. But no luck so far.
I will keep you posted.

Hi ,

Please find enclosed the Log-files.
As far as I can remember this should be the project. But I will also try to reproduce.

Hi ,

If you are comfortable with it, do you have the project that was crashing that you would be comfortable sharing. I attempted to change the level blueprint boolean as you suggested but could not crash the editor.

Hi ,

That is not a problem; when I’m behind that computer I will make a link to it.

However I’m in doubt if this is the project. As far as I can remember it happend with a new project so maybe it (or I) did not save it. I tried to reproduce; but no luck. It happend to me 3 to 6 times (at Home and at work; not the same machines; and I did the “send to Epic”.

I keep you posted

Hi ,

We have not heard from you in quite some time. I am marking this as answered for tracking purposes. However, if you are still experiencing this please respond with the information requested. Thank you!

Hi ,

Sorry I have been very busy; and as I said I’m not sure it is the right project.
Is there something I can look for in the Logs of all my projects that you are looking for.

When it happens again i will post the details and open the project for you in dropbox.

Thanks.

Hi Sean,

As far as I can remember it crashed right away. Before compiling the BP.

So I opened the Level BP
Clicked on add Var
Changed to string (drop down menu)
Typed in a name (did not stick somehow)
Typed again (I guess…)
Then it crashed…

If it happens again I will see if I did something I’n not aware of now

Howdy ,

I have been working with on your issue to try and see if we could get a crash to occur. We have both been unsuccessful with attempt a repro with the steps that you have provided. I have created a string variable and placed it into my level blueprint. I have changed the name multiple times and have had no crashing. Would there be any additional steps that could help with recreating this crash? What version of UE4 would you be working off of? Any additional information would be greatly appreciated.

Thanks and have a great day!

What version of UE4 would you be working off of? 4.2.1?

Could you also send us your dxdiag?

13

4.2.0

I put the dxdiag in the dropbox folder

It happend 2 times again; when I checked on the version

I change the name -

No compile yet -

Use backspace to clear the name-field (above type select) and start typing again. Then it crashes

Howdy ,

Thank you for your bug report. I was able to reproduce the issue with the steps that you have provided. I have also tried to reproduce this in a future build and it has been fixed. The editor would not crash when changing the variable name. I am going to mark this issue as resolved due to it being fixed in a future build. If this issue occurs in the future, feel free to open it up so that it can investigated further.

Thanks and have a great day!
