I want to customize the calendar gif from the
forms-calendar-styling.xsl. In former cocoons I could do this via my
own forms-sample-styling by overwriting the specific part in it (e.g.
the calendar icon).
It seems that for various parts this doesn't works anymore in c2.2
because of the newer dojo implementation we use. The image paths are
hardcoded.
e.g. in the
cocoon-forms/cocoon-forms-impl/src/main/resources/org/apache/cocoon/forms/resources/js/DropdownDateTimePicker.js:
<snip>
dateIconURL: cocoon.formsResourcesUri +
"/js/templates/images/dateIcon.gif"
</snip>
Is there an easy way do do this like it was done before?
If not how can it be done?
InfoPopup.js
MultivalueEditor.js
MultivalueEditorWithSuggestion.js
and probably some more are lacking of the same.
Just out of cursity, can you explain how it could be achieved with earlier
versions?
formsResourcesUri variable is set in forms-field-styling.xsl[1]:
<xsl:value-of select="concat('cocoon.formsResourcesUri = ', $doubleQuote,
$forms-resources, $doubleQuote, ';')"/>
$forms-resources is set in the sitemap[2]:
<map:transform src="resources/forms-samples-styling.xsl">
<map:parameter name="dojo-resources"
value="{servlet:ajax:/resource/external/dojo}" />
<map:parameter name="forms-resources"
value="{servlet:forms:/resource/external/forms}" />
</map:transform>
As you see, servlet:forms:/ is used. Now if you want to change some resources from the form block you need to "override
method" serving forms resources. What's that method and how you should override? The method is a sitemap matcher that
matches requested resource and serves it. How to override it? Steps are pretty simple, you must extend forms block by
creating new one and declaring standard forms block as a super in the connections of newly created block. Then in the
sitemap you can declare matcher that will will match resource you need to replace.
In your case matcher would look like this:
<map:match pattern="resource/external/forms/js/templates/images/dateIcon.gif">
<map:read ...> <!-- you serve your own icon here -->
</map:match>
Then in another block, where you actually use forms you must connect to your
extended block instead of standard one.
Description above gives you idea how it _should_ be done in new setup thanks to conecpts like block/servlet polymorphism
and extension. The trick is that it will not work currently due to issue COCOON-2038[3].
For now, I cannot implement functionality mentioned there myself because I'm badly lacking free time. I offer my help if
you want to do it yourself, though. It shouldn't be that much difficult.
Hope that helps.
