Hi,
\checkparameters seems broken in the current beta. The following example used to work at least with version 2012.06.13
---------------------------------------------------------------------------------
\def\myCom[#1]{%
  \checkparameters[#1]
  \ifparameters
      \getparameters[do][one=1,two=2,#1]
      \doone\ \dotwo
  \else
      #1
  \fi
}
\starttext
\myCom[one]
\myCom[one=one,two=two]
\stoptext
You have to change this on syst-aux.mkiv:
\unexpanded\def\checkparameters[#1]%
- {\syst_helpers_get_empty_parameters#1=@@\_e_o_s_}
+ {\syst_helpers_check_parameters#1=@@\_e_o_s_}
You can also use \doifassignmentelse to check the content of your macro.
\def\mycommand[#1]%
   {\doifassignmentelse{#1}
      {\getrawparameters[mycommand][one=1,two=2,#1]%
       \mycommandone\ \mycommandtwo}
      {#1}}
When you want to use \if… \else … \fi in your command you can use this:
\def\mycommand[#1]%
   {\doifassignmentelse{#1}\donetrue\donefalse
    \ifdone
      \getrawparameters[mycommand][one=1,two=2,#1]%
      \mycommandone\ \mycommandtwo
    \else
      #1%
    \fi}
