Special characters when using <g:set> tag

[Brian Lawson]

I'm trying to use the following to set a variable in my gsp file, but am getting an error:

Code:
<g:set var="createReqInd" value="<span class='required-indicator'>*</span>"/>

Error:
Attribute value quote wasn't closed (var="createReqInd" value="<span class='required-indicator').

Can someone please tell me how to set the variable to this string?

Thanks

I think you can do something like this

<g:set var="createReqInd" value="${'<span class=\'required-indicator\'>*</span>'}"/>

Almost feel negligent for not making sure you were aware of how easy it is to create and custom tags in Grails, something which is perfect for when you want to re-use snippets of gsp/html.

class MyTagLib{

def requiredIndicator = {attrs ->

String indicator = attrs.indicator ?: '*'

out << "<span class='required-indicator'>${indicator}</span>"

}

}

This lives in grails-app/taglib folder under a package of your choosing.

And can then be easily used like this in your GSPs

<g:requiredIndicator />

or

<g:requiredIndicator indicator="req" />

There is lots more to custom tags (use of services, templates, body, etc.)

Hope this helps

Thanks Mikael,

I am very new to Groovy and Grails and I did not know about the custom tags.  Great to know!

I tried this just as a simple "get it working" bandaid, but I'm getting the same error.

Interesting, I tried that myself in an app I have which use Grails 2.2.4 and it worked.
