Erich Duda updated WFCORE-3489:
-------------------------------
    Description: 
When you use control flow constructs consisting of more commands (e.g. {{for-done}}) CLI completion helper should offer commands based on the current context. So if you type {{for}} command, CLI completion should offer {{done}} command. The same applies for other constructs like {{if-else}}, {{try-catch-finally}} and so on.

However if you use these composite operations inside of other composite operations, the following situation occurs.

{code}
[standalone at embedded /] for var in :read-resource
[standalone at embedded /] try
[standalone at embedded /] <TAB>
:                     cd                    connect               deployment-overlay    help                  module                read-attribute        set                   undeploy
alias                 clear                 connection-info       done                  history               patch                 read-operation        stop-embedded-server  unset
attachment            command               deploy                echo                  if                    pwd                   reload                try                   version
batch                 command-timeout       deployment-info       echo-dmr              ls                    quit                  run-batch             unalias
{code}

As you can  see the completion helper offers a {{try}} command although it should offer {{catch}} command.

This issue is caused by design limitation of CLI. When you type some commands inside of for loop block, they are just added into internal list and they are not evaluated until {{done}} command is called. The same applies also for other control flow commands.

The issue appears when you write following commands into the CLI.

{code}
[standalone at embedded /] for var in :read-resource
[standalone at embedded /] try
[standalone at embedded /] <TAB>
:                     cd                    connect               deployment-overlay    help                  module                read-attribute        set                   undeploy
alias                 clear                 connection-info       done                  history               patch                 read-operation        stop-embedded-server  unset
attachment            command               deploy                echo                  if                    pwd                   reload                try                   version
batch                 command-timeout       deployment-info       echo-dmr              ls                    quit                  run-batch             unalias
{code}

This issue is caused by design limitation of CLI. When you type some commands inside of for loop block, they are just added into internal list and they are not evaluated until {{done}} command is called.

The same applies also for other control flow commands such as {{if-else-endif}}
