Problem sending macro to chat box

[Zax]

Hello,

I used to send macros to chat box in several addons like this

local strTemp = "/cast Feign Death"-- for example
DEFAULT_CHAT_FRAME.editBox:SetText(strTemp ) -- sent to Chat Box
ChatEdit_SendText(DEFAULT_CHAT_FRAME.editBox,0)

But PTR 10 complains about a blocked command used by the addon (looks like a secure frame problem).
It still works with emote, if for example strTemp = "/sit"

Is it really a secure problem?
