g:form and g:link question

[wohlgemuth]

hello I got a small question.

basically I got a g:link like this:

<g:link controller="experimentClass" action="attachTo"
params="[callingTarget:'Experiment']"
id="${fieldValue(bean:experiment, field:'id')}">create
Classes</g:link>

which works as it supposed to be and shows me my view here:

http://127.0.0.1:8080/binbase-scheduler/experimentClass/attachTo/1?callingTarget=Experiment

now if I write this as a g:form

<g:form action="attachTo" controller="experimentClass"
id="${fieldValue(bean:experiment, field:'id')}">
    <span class="button"><g:actionSubmit class="create" value="add
Classes" /></span>
    <input type="hidden" name="callingTarget" value="Experiment" />
</g:form>

it generates this link:

http://127.0.0.1:8080/binbase-scheduler/experimentClass/attachTo/1

which gives me this error message:

HTTP ERROR: 404

NOT_FOUND
RequestURI=/binbase-scheduler/experimentClass/attachTo/1

the method attachedTo this:

       
    println "attach method: " + params
    def target = params.callingTarget
    def experimentClass = new ExperimentClass()
   
    experimentClass.belongsTo.each{ p ->
    Class c = p.getValue()
    experimentClass[p.getKey()] = c.get(params.id)
    }
   
    def commingFrom = params.commingFrom
    def commingFromId = params.commingFromId
   
    if(commingFrom == null){
    println "create new comming from fields"
    commingFrom = params.controller
    commingFromId = params.id
    }
    else{
    println "comming from values where already set"
    println commingFromId
    println commingFrom
    }
   
    println "check for errors"
        if(!experimentClass.hasErrors() && experimentClass.save()) {
            flash.message = "ExperimentClass ${experimentClass.id} created"

            redirect(controller:params.controller,action:show,id:experimentClass.id,params:[attached:true,commingFrom:commingFrom,commingFromId:commingFromId])
        }
        else {
            render(view:'create',model:[experimentClass:experimentClass,attached:true,commingFrom:commingFrom,commingFromId:commingFromId])
        }

so nothing to complicated as far as I think.

can somebody explain me what I'm doing wrong here? I think it's
something reall really stupid...


thanks,

g.

Hi Gert.

The <g:actionSubmit ...> Tag uses the "value" attribute as title of the button _and_ name of the action, if you don't specify an "action" attribute.

So, try: <g:actionSubmit class="create" value="add Classes" action="attachTo" />

HTH,
DJ
