Hi,
Can anyone shed a bit more light on how to user the filter parameter? The
documentation states :-
This list is filterable, and if a filter is provided, the "filter" parameter
is appended to the URL, e.g. <fd:selection-list
src="cocoon://pipeline.xml"/> will call, given the "foo" filter value, the
URL cocoon://pipeline.xml?filter=foo.
Where do I specify the parameter value? What I would like to do is :-
In the Template form define the selection list as
<fd:field id="sourcecode" required="true">
<fd:label>Source Code:</fd:label>
<fd:datatype base="string"/>
<fd:selection-list src="cocoon:/sources" cache="request"/>
</fd:field>
Then in the Instance form do something like :-
<ft:widget id="sourcecode">
<filter>${team}</filter>
</ft:widget>
So that in the sitemap I can do :-
<map:match pattern="sources">
<map:generate src="teams.xml"/>
<map:transform src="filterTeamsToSL.xsl">
<map:parameter name="team"
value="{request-param:filter}"/>
</map:transform>
<map:serialize type="xml"/>
</map:match>
Is this how it's supposed to work? I will take another look at the Java
source but any help would be very welcome,

Hi Warrell,
You can set the filter in the fd:on-value-changed javascript.
Using your sourcecode field you'ld need another field in which the
filter is specified, for example:
<fd:field id="filter">
<fd:label>filter</fd:label>
<fd:datatype base="string"/>
<fd:on-value-changed>
<fd:javascript>
var sourcecodeWidget = this.lookupWidget('../sourcecode');
if (this.value != null) {
sourcecodeWidget.setSelectionList('cocoon:/sources?filter=' +
this.value);
} else {
sourcecodeWidget.setSelectionList('cocoon:/sources');
}
</fd:javascript>
</fd:on-value-changed>
</fd:field>
You can also use the following lines to enable/disable the field when
there's no filter specified.
sourcecodeWidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.ACTIVE);
sourcecodeWidget.setState(Packages.org.apache.cocoon.forms.formmodel.WidgetState.DISABLED);
regards,
Pieter
