execute a string from variable as krpano xml

Hello

I have an array of points of view settings this way:

Code

<pov name="pov1" h="181" v="-20 " fovmul="1.17" fish="0.995" act="callwhen(((plugin[video].time) GT 50), setPOV('pov2'));" />
<pov name="pov2" h="181" v="-73 " fovmul="0.83" fish="0.995" act="callwhen(((plugin[video].time) GT 60), setPOV('pov3'));" />

Then I have an action that set the pov using the variables with

Code

<action name="setPOV">
     tween(view.fisheye, get(pov[%1].fish), smooth(%2,%2,%2));
     mul (thisfov, fovST, get(pov[%1].fovmul));
     lookto (get(pov[%1].h), get(pov[%1].v), get(thisfov), smooth(%2,%2,%2));
     get(pov[%1].act);
 </action>

It all works fine but for the act value. I want to put there as string a serie of actions to execute; the example in the code is a single callwhen but potentially more things, for an automated virtual "tour".

How do I execute as krpano xml code the content of a variable as string?

Just do:

Code

pov[%1].act();

I'd never realised it was possible to call any variable as an action in this way.
I haven't seen it documented?

It's documented here:

krpano.com - Documentation - Actions / Scripting Reference

Where 'action' can be either:
the name of a built-in krpano action,
the name of an <action> element,
the name of a variable that contains krpano action code or
the name of a variable that refers to a Javascript function.
