Grails, Params from gsp to Controller

Question

I'm quit new to grails and took over another persons coding

I'm having problems with getting params from my gsp viewer to my groovy controller And when I get the right params it does not change to the right viewer and just goes back to the index sight

<td valign="top" class="value">
    <g:textField name="key" value="${key}" class="form-control" />
</td>

<button class="download">
    <g:link action="show"><g:message code="defualt.button.show.label" default="?Visa" /></g:link>
 </button>

what are the params you want to get to your controller? If you want to add params to your link, you have to use the params-attribute for your g:link-tag : docs.grails.org/latest/ref/Tags/link.html — rdmueller
its the key value from my textField, but with params in g:link it can not seem to find the value from my textfield — Faunus

Your Controller Code:

def key= params.key

Your GSP Code:

<g:form action="show">
<td valign="top" class="value">
    <g:textField name="key" value="${key}" class="form-control" />
    <g:submitButton name="download" value="download" />
</td>
</g:form>
