[Freemarker-devel] Comparison Issue

Hi There,

I started using the Free Marker today.

<#if record.quantity?length == 2>

The above seems to be false. When I switch this to !=2 it seems to be OK. I
just want to show a bit of text when the quantity is 2

What I'm I doing incorrectly?

It should work like that, so the only thing I can think of is that the
length is indeed not 2.

BTW, this mailing list has been retired months ago. There's
***@freemarker.incubator.apache.org instead (see
http://freemarker.incubator.apache.org/mailing-lists.html). Where did
you find the old address?

What kind of data type is record.quantity?

If record.quantity is a *list* (array), use <#if record.quantity*?size* ==
2> (
http://freemarker.incubator.apache.org/docs/ref_builtins_sequence.html#ref_builtin_size
)

If record.quantity is a *string*, use <#if record.quantity*?length* == 2>

If record.quantity is an *integer*, use <#if record.quantity == 2>

That's good point, though ?length on a non-list(ish) value will give
an error instead of a non-2 value.

Eh... I mean, ?size on a non-list(ish) value gives error. As of
?length, that gives error on non-string values, although if someone
uses pure BeansWrapper instead of DefaultObjectWrapper, listable
things can be also strings.

Thanks for getting back.

I am still trying to work out the exact type of quantity. I assumed it was
an int because the out put on the form is always an int. I am trying to
generate a PDF within NetSuite ERP.

None of these seem to work for me. But I can see the text if I use !=

<#if record.quantity?size ==14>TEST</#if>
<#if record.quantity?length==14>TEST</#if>
<#if record.quantity ==14>TEST</#if>

If it's a number then you need "record.quantity == 14". The others
(?size an ?length) should give you an error, as number has no size or
length. Do they not? Something strange is going on there... do they
suppress FreeMarker errors and output nothing? If quantity is a string
that looks like a number, then you should also get an error (for
comparing a string to a number), but then you could use
"record.quantity?number == 14". (BTW, you can easily try these
scenarios on http://freemarker-online.kenshoo.com/)

Hi Daniel,

I sorted the integer issue out but this one is driving me crazy! I can't
see to get two divs floating across each other and show text. This code
works fine in normal html pages but not using free marker! Any ideas? The
text Test is not displayed.

<?xml version="1.0" ?>
<!DOCTYPE pdf PUBLIC "-//big.faceless.org//report" "report-1.1.dtd">
<pdf>
<head>
<style type="text/css">
#details {
background-color: lightblue;
width: 50%;
height: 100px;
}

#summary {
background-color: red;
width: 50%;
height: 100px;
}

</style>
</head>

<body>
<div id="details" style="float:left; display:inline"> <span>test</span>
</div>
<div id="summary" style="float:left; display:inline"> <span>test</span>

It's the browser that does those things (interpreting HTML and CSS),
so it's not related to FreeMarker. The HTML that you generate with
FreeMarker must differ from the one that has worked in some relevant
way. If you generate the same HTML with FreeMarker, it will look
exactly the same.
