Hi,
I tried yours suggestion even reloading Tomcat but I have same error.

A working example is found in:

/alkacon-documentation/documentation_xmlcontent/simpleexample/

and so I have copied its XSD and JSP code into my simple-text.xsd and simple-text.jsp. Error still remains. So I'm missing something but what?

Thanks,

Corrado

Hi Corrado,
I have modified the XSD file using both OpenCmsString and OpenCmsHtml but the problem still remains.
-->Hmm, after applying those changes, did you create a new file of the new type? Editing the old file will probably not work.
You should also clear the core cache or restart Tomcat.

OK, one more idea. In older version you had to define all nodes in the annotation node, even if they are empty.
So try this please:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
	<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>
		
	<xsd:element name="XmlContentDocSimpleTypes" type="OpenCmsXmlContentDocSimpleTypes"/>
	
	<xsd:complexType name="OpenCmsXmlContentDocSimpleTypes">
		<xsd:sequence>
			<xsd:element name="XmlContentDocSimpleType" type="OpenCmsXmlContentDocSimpleType" minOccurs="0" maxOccurs="unbounded"/>
		</xsd:sequence>
	</xsd:complexType>

	<xsd:complexType name="OpenCmsXmlContentDocSimpleType">
		<xsd:sequence>
			<xsd:element name="SimpleText" type="OpenCmsString" />
		</xsd:sequence>
		<xsd:attribute name="language" type="OpenCmsLocale" use="required"/>
	</xsd:complexType>

	 <xsd:annotation>
 		<xsd:appinfo>
			<mappings/>
			<layouts>
				<layout element="SimpleText" widget="TextareaWidgetPlaintext" />
			</layouts>
			<searchsettings/>
			<validationrules/>
			<defaults />
			<relations/>
	   </xsd:appinfo>
	 </xsd:annotation>

</xsd:schema>

-----

I do not understand why you introduced <xsd:annotation> but I have trust in you! ;-)
--> Thanks for trusting me. The reason is, that you cannot use the "TextareaWidgetPlaintext" as type of your element name directly.

Best regards
Kai

Hi Corrado,
two things:
a. There is a space before TextareaWidget (type=" TextareaWidget") change to type="TextareaWidget") b. Anyway I think you have to define the type "TextareaWidget" in the layouts section.

So your simple-text.xsd should look like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
	<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>
		
	<xsd:element name="XmlContentDocSimpleTypes" type="OpenCmsXmlContentDocSimpleTypes"/>
	
	<xsd:complexType name="OpenCmsXmlContentDocSimpleTypes">
		<xsd:sequence>
			<xsd:element name="XmlContentDocSimpleType" type="OpenCmsXmlContentDocSimpleType" minOccurs="0" maxOccurs="unbounded"/>
		</xsd:sequence>
	</xsd:complexType>

	<xsd:complexType name="OpenCmsXmlContentDocSimpleType">
		<xsd:sequence>
			<xsd:element name="SimpleText" type="OpenCmsString" />
		</xsd:sequence>
		<xsd:attribute name="language" type="OpenCmsLocale" use="required"/>
	</xsd:complexType>

	 <xsd:annotation>
 		<xsd:appinfo>
			<layouts>
				<layout element="SimpleText" widget="TextareaWidgetPlaintext" />
			</layouts>
		  </xsd:appinfo>
	 </xsd:annotation>

</xsd:schema>

Please note, that I changed the type to TextareaWidgetPlaintext. Compared to TextareaWidget it strips all HTML code from your Textarea field.
I am not sure about the type="OpenCmsString" in the element section. You possibly need OpenCmsHtml. You have to check that out.

HTH.

Best regards
Kai

Hi Kai,
I'm following your suggestion.

1) I have created a XSD (simple-text.xsd) starting by page you suggested:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
	<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>
		
	<xsd:element name="XmlContentDocSimpleTypes" type="OpenCmsXmlContentDocSimpleTypes"/>
	
	<xsd:complexType name="OpenCmsXmlContentDocSimpleTypes">
		<xsd:sequence>
			<xsd:element name="XmlContentDocSimpleType" type="OpenCmsXmlContentDocSimpleType" minOccurs="0" maxOccurs="unbounded"/>
		</xsd:sequence>
	</xsd:complexType>

	<xsd:complexType name="OpenCmsXmlContentDocSimpleType">
		<xsd:sequence>
			<xsd:element name="SimpleText" type=" TextareaWidget" />
		</xsd:sequence>
		<xsd:attribute name="language" type="OpenCmsLocale" use="required"/>
	</xsd:complexType>
</xsd:schema>

2) I have created a JSP (simple-text.jsp):

<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

<div class="element">
<cms:contentload collector="singleFile" param="%(opencms.uri)" editable="true">

<p>
<cms:contentshow element="SimpleText" /> </p>

</cms:contentload>
</div>

3) then I have created a html file with xmlcontent type and template-elements = "simple-text.jsp ". When I try to edit it I have "An unexpected error happened, but no error message has been provided. " and error log is:

Hi Corrado,
you could create a XML Content type with just one element. This element uses the TextareaWidget type (more info: https://opencms.cse.unsw.edu.au/alkacon-documentation/documentation_xmlcontent/step3-advancedxsd.html).

Betreff: [opencms-dev] Create a txt file with fixed header/footer

Hi all,
I would like to create a template with which to allow editors to create a simple text file (.txt). Each file will have a header and footer and variabile body.

I have created the following simple code (JSP):

<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>

***HEADER***
<cms:include element="body" />
***FOOTER***

When I create a "Page with free text" the editor inserts <p></p> tags around text I'm writing but... I do not want html tags! The best would be have an editor very simple as if I choose to create a "text file".

How can I do it?

I use OpenCms 8.0.1.

Thanks

Corrado
