[jboss-jira] [JBoss JIRA] (WFLY-7398) Tab completion causes NUL characters ('\0') to be injected...sometimes

[Jean-Francois Denise (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13313350#comment-13313350 ] 

Jean-Francois Denise commented on WFLY-7398:
--------------------------------------------

David,
is completion proposing you something for the uri property value? It would help to know the completion sequence.
I guess that the services argument is ruled by a value type and the completion adds automatically for you =[{
Then you are proposed a the list of properties of services, you type part of uri, then TAB "=" is added automatically then you press TAB multiple time (twice it seems).

Is that the steps you have followed?

Thanks.
JF

> I noticed while testing my subsystem that sometimes using tab-complete on an attribute causes NUL ('\0') characters to be injected into the input.  These characters are invisible on the screen but cause XML marshalling to fail as that character is forbidden.
> My "less" output of .jboss-cli-history looks something like this:
> {noformat}
> embed-server --std-out=echo
> cd subsystem=discovery
> ./static-provider=test:add(services=[{uri=^@^@"local", abstract-type="ejb", abstract-type-authority="jboss"}])
> ./static-provider=test4:add(services=[{uri="local", abstract-type="ejb", abstract-type-authority="jboss"}])
> {noformat}
> In the first "test:add" case I used tab-completion; in the second "test4:add" case I typed it out by hand.  The "^@" are in inverse video in less, indicating a NUL character.
