android - Minko - getElementById causes runtime exception to be thrown: TypeError: Minko.tmpElement is null -

-

i using minko , html-overlay feature. in overlay onload()->connect() method have following statements:

...

gameinterfacedom = dom; but1 = gameinterfacedom->getelementbyid("id_but1");    //trouble here ! but2 = gameinterfacedom->getelementbyid("id_but2");   log_info("going bind onclick events..."); if( but1 != nullptr ) {     onbut1 = but1->onclick()->connect(     [](dom::abstractdommouseevent::ptr event)     {       // something...         log_info("clicked button 1");     }); }  if( but2 != nullptr ) {     onbut2 = but2->onclick()->connect(     [](dom::abstractdommouseevent::ptr event)     {       // something...         log_info("clicked button 2");     }); }

...

compiling , running under linux64 works if loaded html not contain but1 , but2 ids, however, same code crashes android , web / html5 (if expected ids not found) following error :

exception thrown: typeerror: minko.tmpelement null

is there workaround such case, or mandatory have expected ids in c++ defined in html ?

thx.
