iwregen error

Hi All,

We are working on Interwoven TeamSite 6.5.0 Service Pack 3.

I am trying to run iwregen clt to regenerate a page having following ext attributes :

TeamSite/Templating/Encoding:
TeamSite/Templating/PrimaryDCR: receivables_authorise_payor_profile_expanded2
TeamSite/Templating/PrimaryDocumentType: hoshelp/help_tool_specific
TeamSite/Templating/PrimaryPT: help_tool_specific.tpl

After executing the command on the above page I get following error:
Use of uninitialized value in scalar chomp at (eval 29) line 77.

Any clue why this error is showing up?

Thanks

You have a bug in your TPL. chomp is a perl function. You are calling chomp with an empty value.

I am getting the same error, I have initialized the variable used in chomp function but the problem is still persisting.

Any idea why?

Any idea? Yeah - there's still a bug in your PT.
Any specific idea? - no, you haven't posted the code for us to look at.

Here's the tpl attached.

Because you initialized the variable doesn't mean squat.

You assign it to $2 after a regex. If that regex fails, $2 and then your variable are null.

Change line 13 to this:



if ($navTitle) {chomp($navTitle);}
else
{
# Do something here because you have no title if you actually care
}

The truly best way to handle this is


 if ($breadcrumb =~m!(.*)>(.*)!){
 $navTitle = $2;
 chomp($navTitle);
} else {
#regex failed
}

Sorry - can't resist - why use two registers when you only need one?

...
if ($breadcrumb =~ m!.*&gt;(.*)!) {
    chomp($navTitle = $1);
}
else {
    # regex failed? chomp($navTitle = $breadcrumb); ?
}
...

I'm not even sure you need the chomp? Are you sure the string value is properly delimited (i.e. do you really want

True, I was just copying his code. Now I should have put the $nav=$2 inside the chomp like you did.
