Hello, Klaus. I think I've found a few bugs in krpano (krpano 1.19-pr8 (build 2016-09-30))
Bug 1. I am calling action, as the parameter pass the text. The action took wrong text. In my case, missing a comma.Example.
Code
...
my_func("'arg1':'value1','arg2':'value2'");
...
<action name="my_func">
trace(%1);
<!-- Result -'arg1':'value1''arg2':'value2' -->
<!-- Must be -'arg1':'value1','arg2':'value2' -->
</action>
Where is the comma? -" 'arg1':'value1','arg2':'value2' "
Bug 2. The textfield plugin (html5) get the wrong width of the text on the mobile. Example.
Code
<layer name="text"
url="%FIRSTXML%/plugins/textfield.swf"
align="lefttop" edge="lefttop"
x="100"
y="100"
html="Hello beautiful world"
css="font-family:Arial; font-size:16px; color:#000000;"
autowidth="true"
autoheight="true"
vcenter="true"
wordwrap="false"
background="true"
keep="true"
onautosized="test_action();"
/>
<layer name="test_layer"
type="container"
align="lefttop" edge="lefttop"
y="100"
width="40"
height="40"
bgcolor="0xff0099"
bgalpha="1.0"
keep="true"
/>
<action name="test_action">
calc(layer[test_layer].x, layer[text].x + layer[text].width);
</action>
As a result, the part of the text cut off. 
I'm doing something wrong or it really bugs?
