Submitting and retrieving data

A Button control of type Submit sends bound data to its source. By default a new document is created. The following example shows an entire page. It contains a Domino document data source (the form named main), an input box bound to an item on the data source, and a submit button. If the user enters a value in the input box and clicks the button, a document is created in the data store.

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
	<xp:this.data>
		<xp:dominoDocument var="document1" formName="main"></xp:dominoDocument>
	</xp:this.data>
	<xp:inputText id="inputText1" value="#{document1.subject}"></xp:inputText>
	<xp:br></xp:br>
	<xp:button value="submit" id="button1">
		<xp:eventHandler event="onclick" submit="true"
			refreshMode="complete" immediate="false" save="true">
		</xp:eventHandler>
	</xp:button>
	<xp:button value="cancel" id="button2"></xp:button>
</xp:view>

A view can be adjusted to retrieve documents:

• The View property pageName specifies an XPage to open if the user selects an element that is a link. In Design mode, click on the View tab for the View control and specify At runtime, open selected document using. By default, the XPage associated with the data source's form is used.
• The View Column property displayAs allows the user to use the element as a link to the underlying document. In Design mode, click on the Display tab for the View Column control and check Show values in this column as links.

The following View control opens the XPage named replace if the user clicks a link, and sets up the first column, which contains the value of the subject item, as a link. When the replace XPage opens, it is populated with any bound data from the target document in the view.

<xp:viewPanel rows="30" id="viewPanel1" pageName="/replace.xsp">
	<xp:this.facets>
	 <xp:pager partialRefresh="true" layout="Previous Group Next"
			xp:key="headerPager" id="pager1">
		</xp:pager>
	</xp:this.facets>
	<xp:this.data>
		<xp:dominoView var="view1" viewName="main"></xp:dominoView>
	</xp:this.data>
	<xp:viewColumn columnName="subject" id="viewColumn1"
		displayAs="link">
		<xp:viewColumnHeader value="subject"
			id="viewColumnHeader1">
		</xp:viewColumnHeader>
	</xp:viewColumn>
	<xp:viewColumn columnName="$1" id="viewColumn2">
		<xp:viewColumnHeader value="last modified"
			id="viewColumnHeader2">
		</xp:viewColumnHeader>
	</xp:viewColumn>
</xp:viewPanel>

The following example shows an entire XPage. It is the replace page opened as a result of clicking on a link in the View control shown in the previous section. The page contains an input box which is populated by the subject item from the retrieved document. Notice also that the XPage has a navigation rule that opens the main XPage after a submission.

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
	<xp:this.data>
		<xp:dominoDocument formName="main" var="document1" action="editDocument" />
	</xp:this.data>
	<xp:inputText id="inputText1" value="#{document1.subject}"></xp:inputText>
	<xp:br></xp:br>
	<xp:button value="submit" id="button1">
		<xp:eventHandler event="onclick" submit="true"
			refreshMode="complete" immediate="false" save="true">
		</xp:eventHandler>
	</xp:button>
	<xp:button value="cancel" id="button2">
		<xp:eventHandler event="onclick" submit="true"
			refreshMode="complete" immediate="true" save="false">
		</xp:eventHandler>
	</xp:button>
	<xp:this.navigationRules>
		<xp:navigationRule outcome="xsp-success" viewId="/main.xsp"></xp:navigationRule>
	</xp:this.navigationRules>
</xp:view>

The following XPage calls the agent saveAgentJava before final submission on a save operation.

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

	<xp:this.data>
		<xp:dominoDocument var="document1" formName="City"
			webQuerySaveAgent="saveAgentJava">
		</xp:dominoDocument>
	</xp:this.data>
	<xp:messages id="messages1"></xp:messages>
	<xp:table>
		<xp:tr>
			<xp:td colspan="2">
				<xp:label
					value="If the field#1 is empty, then the agent will prevent it from being saved"
					id="label0"></xp:label>
			</xp:td>
		</xp:tr>
		<xp:tr>
			<xp:td>
				<xp:label value="Field1:" id="label1" for="inputText1"></xp:label>
			</xp:td>
			<xp:td>
				<xp:inputText value="#{document1.Field1}" id="inputText1"></xp:inputText>
			</xp:td>
		</xp:tr>
		<xp:tr>
			<xp:td>
				<xp:label value="Field2:" id="label2" for="inputText2">
				</xp:label>
			</xp:td>
			<xp:td>
				<xp:inputText value="#{document1.Field2}" id="inputText2"></xp:inputText>
			</xp:td>
		</xp:tr>
		<xp:tr>

				<xp:label value="Agent calculated Value:" id="label3">
				</xp:label>
			</xp:td>
			<xp:td>
				<xp:text escape="true" id="computedField2" value="#{document1.AgentValue}"></xp:text>
			</xp:td>
		</xp:tr>
		<xp:tr>
			<xp:td></xp:td>
			<xp:td>
				<xp:button value="Save" id="button1">

					<xp:eventHandler event="onclick" submit="true"
						refreshMode="complete">
						<xp:this.action>
							<xp:saveDocument var="document1"></xp:saveDocument>
						</xp:this.action>
					</xp:eventHandler>
				</xp:button>
			</xp:td>
		</xp:tr>
	</xp:table>
</xp:view>

Here is the code for saveAgentJava which conditionally cancels the save operation.

import lotus.domino.*;

public class JavaAgent extends AgentBase {

    public void NotesMain() {

      try {
          Session session = getSession();
          AgentContext agentContext = session.getAgentContext();

          // (Your code goes here)
          Document doc = agentContext.getDocumentContext();
          doc.replaceItemValue("AgentValue", "Processed by Java: "+doc.getItemValueString("Field1")+","+doc.getItemValueString("Field2"));
          
          String field1 = doc.getItemValueString("Field1");
          if(field1==null || field1.length()==0) {
        	  doc.replaceItemValue("SaveOptions", Integer.valueOf(0));
          }
          
      } catch(Exception e) {
          e.printStackTrace();
       }
   }
}
