Hi all,
I am using cocoon for building a web application and in particular I am using woody (Cocoon forms) for handling forms.
I have the following problem:
I have modified the example "form_model_gui" to learn how to use the class and struct widgets.
<>I need these widgets because my final goal form is complex and I want to reuse the code.
I have substituted file form_model_gui_data.xml with the following lines:
<?xml version="1.0" encoding="iso-8859-1"?> <page xmlns:util="http://apache.org/xsp/util/2.0"; xmlns:xsp="http://apache.org/xsp"; xmlns:infoutil="http://www.unifactor.com/infocomm/util/1.0"; xmlns:xsp-cookie="http://apache.org/xsp/cookie/2.0"; xmlns:xsp-session="http://apache.org/xsp/session/2.0"; xmlns:xspdoc="http://apache.org/cocoon/XSPDoc/v1"; xmlns:esql="http://apache.org/cocoon/SQL/v2"; xmlns:xsp-request="http://apache.org/xsp/request/2.0";> <title align="center">Anagrafiche trovate:</title> <CONTENT> <PRATINFO> <IDPRAT>226171</IDPRAT> <IDAZ>2</IDAZ> </PRATINFO> <response> <header> <result>1</result> <description>Anagrafica Identificata!!!</description> <messages /> </header> <body> <ANAGRAFICHE > <ANAGRAFICA> <UBICAZIONE> <INDIRIZZO> <DESCRIZIONE>PIAZZA DELLA REPUBBLICA, 1</DESCRIZIONE> </INDIRIZZO> </UBICAZIONE> </ANAGRAFICA>
<ANAGRAFICA> <UBICAZIONE> <INDIRIZZO> <DESCRIZIONE>PIAZZA DELLA REPUBBLICA, 2</DESCRIZIONE> </INDIRIZZO> </UBICAZIONE> </ANAGRAFICA>
</ANAGRAFICHE> </body> </response> </CONTENT> </page>
I replaced the file form_model_gui_binding.xml with the following lines:
<?xml version="1.0" encoding="ISO-8859-1"?>
<wb:context xmlns:wb="http://apache.org/cocoon/woody/binding/1.0"; xmlns:wd="http://apache.org/cocoon/woody/definition/1.0"; path="/page/CONTENT" lenient="true">
<wb:context path="PRATINFO"> <wb:value id="IDPRAT" path="IDPRAT"/> <wb:value id="IDAZ" path="IDAZ"/> </wb:context>
<wb:context id="body" path="response/body">
<wb:new id="ANAGRAFICHE-CLASS"/>
<wb:class id="ANAGRAFICHE-CLASS"> <wb:struct id="ANAGRAFICHE" path="."> <wb:temp-repeater id="REPANAGRAFICHE" parent-path="ANAGRAFICHE" row-path="*" row-path-insert="." virtual-rows="true"> <wb:on-bind> <wb:new id="ANAGRAFICA-CLASS"/> </wb:on-bind> </wb:temp-repeater> </wb:struct> </wb:class>
<wb:class id="ANAGRAFICA-CLASS"> <wb:struct id="ANAGRAFICA" path="ANAGRAFICA"> <wb:new id="UBICAZIONE-CLASS"/> </wb:struct> </wb:class>
<wb:class id="UBICAZIONE-CLASS"> <wb:struct id="UBICAZIONE" path="UBICAZIONE"> <wb:new id="INDIRIZZO-CLASS"/> </wb:struct> </wb:class>
<wb:class id="INDIRIZZO-CLASS"> <wb:struct id="INDIRIZZO" path="INDIRIZZO"> <wb:value id="DESCRIZIONE" path="DESCRIZIONE"/> </wb:struct> </wb:class>
</wb:context>
</wb:context>
and I have substituted the contents of file form_gui_template.xml with the following lines:
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE DOCUMENT SYSTEM "COMMON-ENTITIES-DEF.dtd"> <wd:form xmlns:wd="http://apache.org/cocoon/woody/definition/1.0";>
<wd:widgets>
<wd:messages id="messages"> <wd:label>Errori</wd:label> </wd:messages>
<wd:field id="IDPRAT"> <wd:label>Pratica:</wd:label> <wd:datatype base="string"/> </wd:field>
<wd:field id="IDAZ"> <wd:label>Azienda:</wd:label> <wd:datatype base="string"/> </wd:field>
<!-- Nuovo oggetto per contenere le anagrafiche -->
<wd:new id="ANAGRAFICHE-CLASS"/>
<!-- classe per l'oggetto -->
<wd:class id="ANAGRAFICHE-CLASS"> <wd:widgets> <wd:struct id="ANAGRAFICHE"> <wd:widgets> <wd:repeater id="REPANAGRAFICHE" initial-size="1"> <wd:label>Anagrafiche</wd:label> <wd:widgets> <wd:new id="ANAGRAFICA-CLASS"/> </wd:widgets> </wd:repeater> </wd:widgets> </wd:struct> </wd:widgets> </wd:class>
<wd:class id="ANAGRAFICA-CLASS"> <wd:widgets> <wd:struct id="ANAGRAFICA"> <wd:widgets> <wd:new id="UBICAZIONE-CLASS"/> </wd:widgets> </wd:struct> </wd:widgets> </wd:class>
<wd:class id="UBICAZIONE-CLASS"> <wd:widgets> <wd:struct id="UBICAZIONE"> <wd:widgets> <wd:new id="INDIRIZZO-CLASS"/> </wd:widgets> </wd:struct> </wd:widgets> </wd:class>
<wd:class id="INDIRIZZO-CLASS"> <wd:widgets> <wd:struct id="INDIRIZZO"> <wd:widgets> <wd:field id="DESCRIZIONE"> <wd:datatype base="string"/> <wd:label>Descrizione:</wd:label> </wd:field> </wd:widgets> </wd:struct> </wd:widgets> </wd:class>
</wd:widgets>
</wd:form>
I run the example and the binding seem to work correctly as I can see the form filled with the values from
data file.
I try to submit the form, ( I am expecting an error because the following pipeline is not correct but I expect
to find the xml data I modify stored in form_model_gui_data-result.xml) I get the following error with no xml data output.
uncaught JavaScript exception: at form_model_gui (file:/D:/Programmi/java/eclipse/workspace/cocoon/samples/woody/flow/form_model_gui.js, Line 32) at (resource://org/apache/cocoon/woody/flow/javascript/woody2.js, Line 198): org.apache.commons.jxpath.JXPathException: Cannot create a relative context for a non-existent node: /ANAGRAFICA
org.apache.avalon.framework.CascadingRuntimeException: uncaught JavaScript exception: at form_model_gui (file:/D:/Programmi/java/eclipse/workspace/cocoon/samples/woody/flow/form_model_gui.js, Line 32) at (resource://org/apache/cocoon/woody/flow/javascript/woody2.js, Line 198): org.apache.commons.jxpath.JXPathException: Cannot create a relative context for a non-existent node: /ANAGRAFICA
Am I using the right approach or class and struct elements have to be used in another way?
I cannot understand why binding works during loading but not for saving the form.
I used temp-repeater because I have no id for the repeater elements. Maybe there is another way to use the normal repeater or can someone address me to find some documentation on temp-repeater?
Maybe this iussue is solved in CForms so it is better for me to migrate to the new enviroment? (Migration is an already scheduled job but I need to be sure it works before migrating).
Thanks to all and sorry about my bad English
