[daisy] Re: Example .js snippet for accessing fields

[Robert Cecil]

I think I found it.

Here's my flow.js snippet:

		var schema = repository.getRepositorySchema();
		var selectionList = schema.getFieldTypeByName("StudyType",  
false).getSelectionList();
		var typeArray = new Array();
		var selectionListItems = selectionList.getItems();
		for (var i = 0; i < selectionListItems.length; i++) {
			var listItem = selectionListItems[i];
			var listLabel = listItem.getLabel(java.util.Locale.getDefault());
			typeArray[i] = { value:listItem.getValue(), label:listLabel };
		}
	
        // show form
        var viewData = new Object();
        viewData["CocoonFormsInstance"] = form.form;
        viewData["pageContext"] = daisy.getPageContext();
        viewData["submitPath"] = mountPoint + "/" + siteConf.getName 
() + "/ext/forms/conceptproposal";
        viewData["locale"] = locale;
        viewData["navigationTree"] = navigationData;
        viewData["formTemplate"] = daisy.resolve 
("conceptproposal_form_template.xml");
        viewData["studytypelist"] = typeArray;
        cocoon.sendPage(daisy.getDaisyCocoonPath() + "/ 
GenericFormPipe", viewData);

Here's how my form consumes it:

     <fd:field id="proposal-studytype" required="true">
       <fd:label>Type of study:</fd:label>
       <fd:datatype base="string"/>
       <fd:selection-list type="flow-jxpath" list-path="studytypelist"
	                     value-path="value" label-path="label">
	  </fd:selection-list>
     </fd:field>
