Closed elonderin closed 3 years ago

elonderin commented 3 years ago

in my gitlab yaml i did this accidentally:

.env-vars: &env-vars
  - 'echo -e "section_start:`date +%s`:envvars\r\e[0Kenvvars" '
  - *env-vars
  - 'echo -e "section_end:`date +%s`:envvars\r\e[0Kenvvars" '

and when opening the quick outline i got a famous:

java.lang.StackOverflowError
    at de.jcup.yamleditor.script.YamlScriptModelBuilder.appendSequence(YamlScriptModelBuilder.java:162)
    at de.jcup.yamleditor.script.YamlScriptModelBuilder.buildNode(YamlScriptModelBuilder.java:107)
    at de.jcup.yamleditor.script.YamlScriptModelBuilder.createYamlNodeAndAddToParent(YamlScriptModelBuilder.java:185)
    at de.jcup.yamleditor.script.YamlScriptModelBuilder.appendSequence(YamlScriptModelBuilder.java:162)
...

note: when re-opening the editor the outline view is empty
