如何从控制器设置gsp元素属性值

Question

I have a field that can store data with html tags and format intact. For example: Field A has following data:

Comment 1 by User 1 01/01/2014: Jhyap 
<br> 
Comment 2 by User 2 01/05/2014: Momo kasto mitho
<br>
Comment 3 by User 3 01/05/2014: Launa k garney aba

Currently on using <g:fieldValue bean="${Instance}" field="Field A"/> the gsp displays field as Comment 1 by Saila 01/01/2014: Jhyap<br>Comment 2 by Kaila 2 01/05/2014: Momo kasto mitho<br>Comment 2 by Kaila 2 01/05/2014: Momo kasto mitho<br>

Is it possible to display this field's value in GSP like this:

Field A:

Comment 1 by Saila 01/01/2014: Jhyap
Comment 2 by Kaila 2 01/05/2014: Momo kasto mitho
Comment 3 by Maila 3 01/05/2014: Launa k garney aba

Thanks for your time!

Answer 1

For the sake of avoiding Cross Site Scripting (XSS) Grails escape all the html content in ${} expression in GSPs, therefore you can use

${raw(htmlString)}

Answer 2

Instead of using the fieldValue tag you could just print out the value directly. Like this: ${Instance['Field A']} or maybe ${Instance.'Field A'} .
