/setblock ~ ~1 ~ minecraft:wall_sign 4 replace {Text2:"{clickEvent:{action:\"run_command\",value:\"say Hello world!\"},text:\"TEST\"}"}
This command works in 1.8.8 if click to sign.
You need to stricktify your json in the sign's Text1/2/3/4 tags, see MC-83460
So?
/blockdata ~ ~1 ~ {Text1:"{text:1,clickEvent:{action:run_command,value:\"say Hello World!\"},bold:true}",Text2:"{text:2,bold:true}",Text3:"{text:3,bold:true}",Text4:"{text:4,bold:true}"}
Still not working
You didn't read MC-83460 at all, did you
Use
/blockdata ~ ~1 ~ {Text1:"{\"text\":\"1\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"say Hello World!\"},\"bold\":\"true\"}",Text2:"{\"text\":\"2\",\"bold\":\"true\"}",Text3:"{\"text\":\"3\",\"bold\":\"true\"}",Text4:"{\"text\":\"4\",\"bold\":\"true\"}"}
Work! Thank you!)
Please provide the exact command you're using.
