<action name="test">

</action>
test("//krpano.com");
result null

right.. something is odd here :

in test2() "//krpano.com" gets logged
in test1() it doesnt, and logging "after" is not executed at all ....

strange

Code

<action name="test1">
trace('before');
debug(%1);
trace('after');
</action>


<action name="test2" autorun="onstart">
debug("//krpano.com");
test1("//krpano.com");
</action>

Hi,

note - the %NN is text-placeholder!

so the:

Code

trace(%1);

becomes:

Code

trace(//krpano.com);

and '//' is a comment, so the final code will be just:

Code

trace(

That's invalid code and breaks the following actions, but the trace itself gets called.

If you want to avoid that problem, either quote the parameter:

Code

trace('%1');

or better use a localscope action and argument variables:

Code

<action name="test" scope="local" args="msg">
trace(get(msg));
</action>

Best regards,
Klaus
