<h:form>
<b:commandButton value="boton" update="@this"/> <br/>
</h:form>
</h:body>
</html>
is related to de update field
I don't think this bug has anything to do with BootsFaces. Maybe the error message is correct. Have you registered the *.xhtml files with the FacesServlet?
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

<servlet-mapping>

I did:

<servlet-mapping>

</servlet-mapping>
anyway it dont broke anything just log
Which URL are you using? If you configure your FacesServlet like so, it shows the index.xhtml when you navigate to http://localhost:8080/index.xhtml.
I also have the error "com.sun.faces.context.ExternalContextImpl#798 - JSF1091: No mime type could be found for file null...." I'm using In Mojarra 2.3.14. It occurs in a <b:dataTable> element with an Ajax onselect handler "onselect="ajax:listBean.onSelect(entity, typeOfSelection, indexes)". Selecting a row in the table causes a POST request to trigger the onSelect() method which works correctly. By putting a breakpoint at the line mentioned in the message, I identified the cause. During the rendering phase, all the resources in the viewRoot are processed in PartialViewContextImpl.renderComponentResources(). The error message appears once for each "special" bootsfaces resource, for example when the resource is a net.bootsfaces.listeners.InternalIE8CompatiblityLinks object. It was also occurring on the dataTables-related js and css which were fetched from the CDN. By forcing those to be retrieved locally, the warning for those resources disappeared. I agree it's just a warning if the project is in development stage, but it's rather annoying and misleading.
Yes, it would be nice if there would be a fix for this (not using the CDN is a rather drastic measure)
About this PR I think the error comes from a missing type = "text / javascript" tag in InternalIE8CompatiblityLinks

found the point of the log message

I tried my approach, but it didn't help. The question is why is this message coming?
I'm afraid development of BootsFaces has slowed down considerably. We'll never manage to address this issue. Let's close it.
