[t5.4-beta-10] java.lang.NullPointerException: Unable to delegate method invocation to property 'response'

I'm trying to use a complicated bootstrap template that has numerous
dependencies. So its possible that I'm missing one. I've put my asssets in
META-INF/assets folders under my resources directory (i.e. source folder
for TML files.)

Now I'm facing this exception and many more (The full console output is
attached). For instance consider the following stacktrace. First I see a
warning with the message "/lte/img/avatar2.png" then a strange exception
that I can't make anything out of. I checked that the file
"/lte/img/avatar2.png" exists in the mentioned path and it is. So how can I
resolve/trace this ?

I've just read a link you sent before, this link:
http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/META-INF-assets-in-5-4-td5714677.html

I understood that Tapestry should throw an exception explaining that I
should place my asset in "META-INF/assets" folder but this isn't the case.
I also don't think that's clear enough though because META-INF folders are
usually placed next to WEB-INF folder in the webapp directory, not in the
classpath.

I had these images references this way *<img src="img/avatar.png" />* while
I should've had them referenced this way *<img

Re: [t5.4-beta-10] java.lang.NullPointerException: Unable to delegate method invocation to property 'response'

Posted by Muhammad Gelbana <m....@gmail.com>.
Sorry I couldn't reply earlier. This is the statement at line 116:
(BTW, I created a new maven project using the quickstart archetype for
5.4-beta-10 and didn't modify anything in the code except that:

   1. I commented an event handler in the *Index.java* file
   2. Removed all the content in *Index.tml* except the basic tags (i.e.
   html) since all the static content is displayed in the *Layout.tml* file
   because I'm still testing. I tend to move forward bit by bit with tapestry
   so when I weird exception is thrown, I can at least guess what exactly did
   I do wrong.

I checked that the file "/lte/img/avatar2.png" exists in the mentioned path and it is. So how can I resolve/trace this ?
