Hi,
It seems that only one combobox can be used at the same time.
that's only true for the "default" behavior of the combobox plugin,
by default it looks after loading for all actions which are named like "combobox:...." and adds them...
but when using the manually adding method, then more comboboxes are possible:
possible to use more than 1 combobox?
plugin[combobox].selectitem(Item_X); does not work when called from <krpano onstart="">
that has something to do with the plugin loading,
it takes a bit until the plugin was loaded, and it's possible that the "onstart" will be called before the loading was one,
solutions could be:
1. to use - preload="true"- for the combobox plugin (then it will be forced to be loaded before onstart)
2. or use the "onloaded" event of the plugin, it will be called when the plugin was loaded it is and ready for use,
When Combobox Items are set with additem(Item_X1, something_to_do ); instead of <action name=combobox:Item_x> then it is not possible to call action(combobox:Item_x).
additem() will not create a new action,
it will assign the given code to the item,
Perhaps it can be interesting to add a new attribute, something as an Item_ID... With an attribute like this it would be possible to call a Combobox Item instead if the value of that Item is modified.
of course, an item id, would be better

(a complete new combobox plugin (not based on the Flash combobox anymore) with more possibilities is still planned)
best regards,
Klaus
