Hi Derek

Well I can help you with the resources ;-)
They are located in jar-files. Depending on the resources you are using=20
Cocoon-forms-block.jar: org.apache.cocoon.forms.resources.*
Dojo-rsrc-xxxxxxx.jar: org.apache.cocoon.dojo.rerources.*

I usually make them available using the following pipeline:
      <map:match pattern=3D"**_cocoon/resources/*/**">
        <map:select type=3D"resource-exists">
          <map:when test=3D"resources/{2}/{3}">
            <map:read src=3D"resources/{2}/{3}"/>
          </map:when>
          <map:when test=3D"resource://{2}/{3}">
            <map:read src=3D"resource://{2}/{3}"/>
          </map:when>
          <map:otherwise>
            <map:read =
src=3D"resource://org/apache/cocoon/{2}/resources/{3}"/>
          </map:otherwise>
        </map:select>
      </map:match>
This way I can override the resources in the jars with my alternate
implementations.

Hope this helps.

Chris

Betreff: AJAX in CForms... not that simple?!

I have been working with Cocoon + CForms for a while now,=20
but now have to deal with some more complex processing=20
requirements.  I had thought this would be a simple matter,=20
but alas not...
=20
Issue 1.  I have heavily customized stylesheets that I use for=20
form display.  Going back to the default stylesheets is problematic.
=20
Issue 2.  Locating the resources?  This message:
http://marc.info/?l=3Dxml-cocoon-users&m=3D111323898129449&w=3D2=20
(and others) refer to the WEB-INF/classes/org/..../forms/resources
directory. =20
This I simply cannot find.  I have =
"WEB-INF/classes/org/apache/cocoon/forms"

but no resources directory in sight.
=20
I have tried to copy & use the various files directly from the Cocoon
installation files... but to no avail.
=20
In the end, I have tried to create a small test app, based on the car=20
selector sample, with details as shown below.
=20
Although the form displays just fine, it does not exhibit any of the=20
dynamic behavior of the original sample.  Comparison of the source code=20
of the two web pages shows them to be the same!
=20
What (probably obvious) element/s am I missing?
=20
Thanks
Derek

<!-- CAR SELECTOR FILES AND SETUP -->
=20
I have the following directory/files:
=20
flow/forms_flow_example.js=20
=20
This file is stripped down to:
cocoon.load("resource://org/apache/cocoon/forms/flow/javascript/Form.js")=
;
function selectCar() {
    var form =3D new Form("cocoon:/carselector_form");
    form.lookupWidget("make").setValue(cocoon.parameters.defaultMake);
    form.showForm("carselector-display-pipeline.jx");
    cocoon.request.setAttribute("carselectorform", form.getWidget());
    cocoon.sendPage("carselector-success-pipeline.xsp", {make:
form.lookupWidget("make").value, type: form.lookupWidget("type").value,
 model: form.lookupWidget("model").value}
    );
}
=20
resources/cforms.js
resources/cocoon-ajax.js
resources/forms-lib.js
resources/forms.css
resources/jx-macros.xml
=20
stylesheets/forms/forms-advanced-field-styling.xsl

The above sheet I have altered as follows:

  <xsl:import  href=3D"forms-field-styling.xsl"/>
  <xsl:include href=3D"forms-calendar-styling.xsl"/>
  <xsl:include href=3D"forms-htmlarea-styling.xsl"/>
<!--

    <script =

    <xsl:apply-templates select=3D"." mode=3D"forms-calendar"/>
    <xsl:apply-templates select=3D"." mode=3D"forms-htmlarea"/>
  </xsl:template>
-->


stylesheets/forms/forms-field-styling.xsl

In this above sheet I have altered the scripts to point directly at
the files in the same app. ie.
  <xsl:template match=3D"head" mode=3D"forms-field">
    <script src=3D"../../resources/forms-lib.js" =
type=3D"text/javascript"/>
    <script src=3D"../../resources/cocoon-ajax.js" =
type=3D"text/javascript"/>
    <script src=3D"../../resources/cforms.js" type=3D"text/javascript"/>
    <link rel=3D"stylesheet" type=3D"text/css"
href=3D"../../resources/forms.css"/>
  </xsl:template>

stylesheets/forms/forms-page-styling.xsl
stylesheets/forms/forms-samples-styling.xsl

In this aboove sheet I have altered the includes to point directly at
the other files in the same directory ie.

  <xsl:include href=3D"forms-page-styling.xsl"/>
  <xsl:include href=3D"forms-advanced-field-styling.xsl"/>
=20
stylesheets/doc/simple-page2html.xsl

tables/carselector_form.xml
tables/carselector_template.xml
tables/carselector_success_jx.xml
=20

  <map:transformers default=3D"xslt">
   <map:transformer name=3D"browser-update"
