I am frequently (and randomly it seems) getting a 4001 error while
parsing velocity page /templates/wysiwyginput.vm when loading pages for
inline-edits.
This is happening both on fields that have wiki-syntax (2.0) content and
fields that while able to take wiki-syntax content, have only plain
text. (i.e. "Lengthy, detailed information as needed. A good use of this
would be training for new application features. This will be limited to
text. If more is needed the user should be redirected to more detailed
help documentation.")
If the inline-edit page is immediately hard-refreshed (<CTRL>+<F5>), the
message usually goes away and the correct content is displayed. However,
users often don't notice the problem until 3-5 edits later, once the
error message output has been saved to the field. (see log messages
below)
The setup that I have is:
-- Page
-- 1 Class Object of type A w/ multiple properties (incl. several
textarea fields)
-- Many Class Objects of type B w/ multiple properties (incl.
several textarea fields)
-- Many Class Objects of type C w/ multiple properties (incl.
several textarea fields)
The problem has occurred for objects from all three classes, and there
doesn't seem to be any consistency as to which class/property it happens
to.
The biggest thing that I can't figure out is that for one load of the
page it's fine, then it's broken, then (without changing the underlying
data or code) it's fine again.
Thanks!

Hi,
It looks as though you have discovered a concurrency bug. What is
the version of your installation?
If you feel like creating an issue on jira.xwiki.org, that would be
great. I will look in to this.
A few questions:
Does it happen more often when there are a lot of users?
Just confirming the page is in /inline/ mode and not /preview/ or
/edit/? I ask because The log shows
"h.com/xwiki/bin/preview/Project" and the failing template is
"/templates/wysiwyginput.vm".
Thanks for the report.

This is happening both on fields that have wiki-syntax (2.0) content and

If the inline-edit page is immediately hard-refreshed (<CTRL>+<F5>), the
message usually goes away and the correct content is displayed. However,
users often don't notice the problem until 3-5 edits later, once the
error message output has been saved to the field. (see log messages
below)
The setup that I have is:
-- Page
-- 1 Class Object of type A w/ multiple properties (incl. several
textarea fields)
-- Many Class Objects of type B w/ multiple properties (incl.
several textarea fields)
-- Many Class Objects of type C w/ multiple properties (incl.
several textarea fields)
The problem has occurred for objects from all three classes, and there
doesn't seem to be any consistency as to which class/property it happens
to.
The biggest thing that I can't figure out is that for one load of the
page it's fine, then it's broken, then (without changing the underlying
data or code) it's fine again.

Caleb,
Thanks for the quick response. I'll keep digging into it. It's been
difficult to reproduce consistently, but it has happened in my dev
environment where I am the only user (though I'm not sure if I had the
document open in multiple tabs...). It definitely happens more
frequently in our production system, though the percentage may be about
the same (we have one user who is using that functionality on a regular
basis (i.e. that's pretty much all she's been doing for the past several
weeks).
I'll go file the issue now.
Thanks!

Hi,
It looks as though you have discovered a concurrency bug. What is the
version of your installation?
If you feel like creating an issue on jira.xwiki.org, that would be
great. I will look in to this.
A few questions:
Does it happen more often when there are a lot of users?
Just confirming the page is in /inline/ mode and not /preview/ or
/edit/? I ask because The log shows "h.com/xwiki/bin/preview/Project"
and the failing template is "/templates/wysiwyginput.vm".
Thanks for the report.

I am frequently (and randomly it seems) getting a 4001
error while
parsing velocity page /templates/wysiwyginput.vm when loading pages
for inline-edits.
This is happening both on fields that have wiki-syntax (2.0) content
and fields that while able to take wiki-syntax content, have only
plain text. (i.e. "Lengthy, detailed information as needed. A good use
of this would be training for new application
features. This will be
limited to text. If more is needed the user should be redirected to
more detailed help documentation.")
If the inline-edit page is immediately hard-refreshed (<CTRL>+<F5>),
the message usually goes away and the correct content is displayed.
However, users often don't notice the problem until 3-5 edits later,
once the error message output has been saved to the field. (see log
messages
below)
The setup that I have is:
-- Page
-- 1 Class Object of type A w/ multiple properties (incl. several
textarea fields)
-- Many Class Objects of type B w/ multiple properties (incl.
several textarea fields)
-- Many Class Objects of type C w/ multiple properties (incl.
several textarea fields)
The problem has occurred for objects from all three classes, and there
doesn't seem to be any consistency as to which
class/property it
happens to.
The biggest thing that I can't figure out is that for one load of the
page it's fine, then it's broken, then (without changing the
underlying data or code) it's fine again.
Thanks!
