How to cancel a cforms usecase
Hi all,
I'm implementing a cforms usecase and I'm having trouble with the way
of cancelling it. I've implemented it as suggested in the file
dynamicrepeater_template.xml included in the cforms module. It says:
[quote]
<ft:form-template method="POST" ajax="true">
...
...
<input type="hidden" id="lenya.submit" name="lenya.submit" value="ok"/>
...
...
<ft:widget id="ok"/>
<!-- If you want a cancel button you beware to change the
lenya.submit value!!! like: -->
<br/>
<input i18n:attr="value" type="submit" name="cancel"
value="Cancel" onClick="document.getElementById('lenya.submit').value='cancel'"/>
...
...
[/quote]
I've added a cancel widget in my form definition (otherwise I get an
error message) and have implemented the submit and cancel buttons
following this example. It doesn't work because clicking on the Cancel
button generates the following request parameters, among others:
[quote]
PARAM: 'forms_submit_id' VALUES: '[cancel]'
PARAM: 'lenya.submit' VALUES: '[cancel]'
[/quote]
and they don't match the following if-else clause in usecases.js:
[code]
//HEADSUP: Cform do not allow id="submit" anymore. Use id="ok" for
now (till it is settled on cocoon-dev).
if (cocoon.request.getParameter("submit")||
cocoon.request.getParameter("lenya.submit")=="ok") {
//Execute the usecase
} else if (cocoon.request.getParameter("cancel")) {
//Cancel the usecase
}
[/code]
I'm new to Cforms and I don't know why the cancel button changes its
name to forms_submit_id when the form is submitted.
I'd like to know if I'm missing something obvious or if there is a
workaround to this problem.
Thanks,
Paloma

Hi Paloma,
I just had a quick look but it seems that the cform example in the trunk
is broken. I cannot submit anymore. Canceling is not working either.
http://lenya.zones.apache.org:9999/default/authoring/doctypes/cforms.html?&lenya.usecase=edit.cforms
I just fixed this (I hope) with r421571 but the server will be updated
tonight.

That needs to have ajax="false", I fixed the sample.

You cannot use the a cancel widget since it acts different then we
expect in the usecase.js.

Because the cform integration is more a hack in the usecase.js then
anything else. We would welcome a better integration but till now no one
found the time.
The setting of the hidden (!!!) field lenya.submit to cancel is a
workaround to trigger a cancel.

Please try again after an update. If it still fails or if it works,
please let us know.
