Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UMG Widget crashes on compile

I've created a UMG Widget, and the Editor crashes every time I click to Compile it. I believe it is the same error each time.

Here is the callstack from the Crash Reproter:

Any solutions to this problem? I keeps happening on 4.6.1 when selecting UMG widget elements and compiling. Project runs fine after restarting, though.

Could you reproduce it using a source build compiled in debug mode?

avatar image Everynone Jan 12 '15 at 10:50 AM

I have not tried. I can confirm it was present in 4.5.

Reproduction of this issue in a new project / blueprint is difficult. This never happens in newly created widgets. The widgets that develop this behaviour can be very simple, though - I got to a point where a Sizebox and an Image (no variables or references) would crash 100%.

The worst/best part is that the project still runs fine, but one can no longer edit the widget. The widget's Graph can be compiled, but compiling the Designer after selecting any of its elements (the widget does not even gets flagged as dirty) results in the error mentioned by the OP.

Also, a new widget recreated from scratch with the same elements may or may not crash. Seems pretty random.

Waiting for 4.7 (or feedback on this crash) rather impatiently. :|

It's been a seemingly random occurrence for me as well. I've gotten into the habit of saving my UMG widgets, and doing a Save All, before compiling a widget; just so I don't lose any work.

I have also noticed that the crash happens when compiling after making changes in Designer mode; changes in Graph mode will compile just fine.

This behaviour can be somewhat mitigated by saving (as you said) and closing the Designer window if switching to the Graph helps little.

Still, this issue persists for now. I tried avoiding direct blueprint communication and any circular references. It rarely helps, though.
