Hi,
I'm using 1.1-SNAPSHOT lift release and am experiencing strange
behaviour when trying to output a NodeSeq formed from nested NodeSeq &
Scala code.
To highlight the problem let me show you the code I'm trying to
execute:
-----------------------------------
def listFilesInDir(dirName:String): NodeSeq =
{
Log.info("Recursing for: " + dirName)
val files = (new java.io.File(dirName)).listFiles
def playFile1() = "AAA"
<li class="fileElem" id="dir">{dirName}</li>
<ul>
{files.flatMap(f => {
if (f.isDirectory())
{
Log.info("Directory: " + f.toString)
listFilesInDir(f.toString)
<span></span>
}
else
{
Log.info("Regular file: " + f.getName)
<li class="fileElem" id="regfile">
{SHtml.link("", () => playFile1,
Text("Something")) } /* Problem in this line */
</li>
}
}
)}
</ul>
-----------------------------------
I'm trying to render the output of the above function in a comet
actor. The problem i see is with the highlighted line of code. When
the execution reaches this line of code, it gets stuck; the function
doesn't return and i don't get a NodeSeq to render.
However, for some reason if I change the highlighted line of code to
say:
{f.getName}
I get the proper NodeSeq which lists all the files in the directory.
Seems to me that the SHtml class functions are encountering an error
scenario(frm which its unable to recover). I've tried a couple of
SHtml functions(a, text, link, submit etc.) all of them show the same
problem, but if I use some other scala code it executes properly.
Could anyone look into this and verify whether this is indeed a bug
with the SHtml functions?
Thanks,
Soumik
