[Ragan, S. <sr...@bc...>]

That looks like a generic IE error message - look at the bottom of the page.
It probably has something like - 

HTTP 500 - Internal server error 
Internet Explorer 

My guess is you're timing out before the results can be served up.

Subject: [htmltmpl] Is their a maximum amount of data that can be
displayed by HTML:: Template?


I am using HTML::Template to display software/hardware inventory data being
pulled from a database.  I have 11 subroutines that pull out data for
different categories of data (hardware, os, memory, installed programs, etc)

The data is stored in arrays:

@rows1
@rows2
...
@rows11

The contents of @rowsX is an array of hashes.  The subroutine populates each
@rowsX like so:

[code]
push @rows, { 	idevice => $idevice,
			igroup => $igroup,
			ifield => $ifield,
			ivalue => $ivalue,
		};

Once all of my arrays have been populated I then stuff all of it into
HTML::Template like this:

my @headers = (	{category => 'summary', cat_title => 'Summary', rows1 =>
\@rows1},
{category => 'cpu', cat_title => 'CPU', rows2 => \@rows2},
{category => 'memory', cat_title => 'Memory', rows3 => \@rows3},
{category => 'os', cat_title => 'Operating System', rows4 => \@rows4},
{category => 'share', cat_title => 'Share', rows5 => \@rows5},
{category => 'lgroup', cat_title => 'Local Groups', rows6 => \@rows6},
{category => 'network', cat_title => 'Windows Network', rows7 => \@rows7},
{category => 'data', cat_title => 'ODBC Data Sources', rows8 => \@rows8},
{category => 'programs', cat_title => 'Installed Programs', rows9 =>
\@rows9},
{category => 'license', cat_title => 'Licenses', rows10 => \@rows10},
{category => 'environment', cat_title => 'Environment', rows11 => \@rows11}
);


$tmpl_cmp_nfo->param(	headers => \@headers);



This all works beautifully on the majority of my inventories, but I have
found a few that will not display.  I have built all of the appropriate
error checking into my app, but none of those errors display when I come
across one of these anomolous inventories.  The only thing that shows up in
my browser is "page cannot be displayed".  

I have found that the amount of information contained in an inventory that
does not work is substantially larger than the information in one that does
work.  If I comment out some of the data being retrieved in an anomolous
inventory, then it will display as well.

Like this:

my @headers = (	{category => 'summary', cat_title => 'Summary', rows1 =>
\@rows1},
{category => 'cpu', cat_title => 'CPU', rows2 => \@rows2},
{category => 'memory', cat_title => 'Memory', rows3 => \@rows3},
#{category => 'os', cat_title => 'Operating System', rows4 => \@rows4},
#{category => 'share', cat_title => 'Share', rows5 => \@rows5},
{category => 'lgroup', cat_title => 'Local Groups', rows6 => \@rows6},
{category => 'network', cat_title => 'Windows Network', rows7 => \@rows7},
{category => 'data', cat_title => 'ODBC Data Sources', rows8 => \@rows8},
{category => 'programs', cat_title => 'Installed Programs', rows9 =>
\@rows9},
{category => 'license', cat_title => 'Licenses', rows10 => \@rows10},
{category => 'environment', cat_title => 'Environment', rows11 => \@rows11}
);


$tmpl_cmp_nfo->param(	headers => \@headers);

It doesn't matter which of the @rowsX I leave out of the display, I just
have to leave some of them out and then it all works.  

This makes me wonder if there is a limitation to the amount of data that can
be displayed by HTML::Template.  Any ideas?

Thanks,

Tyler Hepworth
