I was able to fix the NullPointer by adding this code
abovecycle.getParameter(_childId) in the rewindFormComponent() method of
DynamicSelectionList:
String suffix = ;
if (getIndex() 0) {
suffix = _ + (getIndex() - 1);
}
_childId = getId() + suffix;
It looks like it's working
I have just downoloaded
manTap4Library-1.3-src.jar from Tassel and verified
all the files
are same as my local copy. I am running Tap 4.0.2
as well and the component works.
It is strange that you have problem with it.
Anyway, I am glad you have found a solution.

It seems to me that this component is broken. When I try to test this my
browser complains about javascript errors and the child list stays
empty. I don't know whats wrong with it and I'm too lazy to debug it.
You should contact the author of the component to get a fix.

I'm trying to get the DynamicSelectionList component working in an
existing Tapestry 4.0 project.
http://lombok.demon.co.uk/tapestry4Demo/
I copied all of the source files from the custom class example into my
own packages, but when I try to submit the form on the page, I get this
error:
Well, some mandatory parameter of some component must not be null :-)
How about giving us a bit more? Page template, page class, line in the
template at which the error occurs...

Thanks for the quick response. The source is exactly as here except I
changed the package names:
http://lombok.demon.co.uk/tapestry4Demo/pages/dynamicSelectionList/TestDSLComponent2Source.html
The error occurs on line 7 of TestDSLComponent2.page:
page-specification
Please give us the exact error message (doesn't need to be the whole
stack trace but a few more lines from which we can see at which point
the exception is thrown would be helpful...).
