[kepler-users] kepler parameters

[Christopher Brooks]

Hi Kianwee,
Yes, to add a parameter, right click on the FileParameter and select 
"Configure Attribute".
Then select "Add".
For the Name field, enter allowFiles or allowDirectories.
For the Default value, enter true or false
Then hit OK.

You were pretty close in your solution, the issue is that true and false 
are booleans, 0 and 1 are integers.  Integers do not losslessly convert 
to booleans.

To get a check box,  right click on the FileParameter and select 
"Configure Attribute"
Then click on "Preferences"
You can then click different styles for the attribute.  Checkbox is one 
such style.

I've attached an xml file that has a simple model.  You will need to 
browse to a local file on your machine,
the model probably has /Users/cxh hard coded into it.
