displayValueType

Returns Number

Sample

fallbackValueList

Gets or sets the fallback valuelist.

Returns JSValueList

Sample

var myValueList = solutionModel.getValueList('myValueListHere')
 //get fallback value list
var fallbackValueList = myValueList.fallbackValueList

globalMethod

The global method of the valuelist is called to fill in or adjust the values of the valuelist. The method returns a dataset with one or two columns, first column is the display value, second column is real value(if present). The valuelist will be filled in with the dataset data. If second column is not present real value and display value will be the same. The method has to handle three different scenarios:

  1. 'displayValue' parameter is not null, this parameter should be used to filter the list of values(in a typeahead fashion)

  2. 'realValue' parameter is specified, that means value was not found in current list, so must be specified manually. In this case method should return only one row in the dataset, with the missing value, that will be added to the valuelist

  3. 'realValue' and 'displayValue' are both null , in this case the complete list of values should be returned.

Scenario 1 and 3 will completely replace any older results in the valuelist while scenario 2 will append results.

In find mode the record will be the FindRecord which is just like a normal JSRecord (DataRecord) it has the same properties (column/dataproviders) but doesnt have its methods (like isEditing())

The last argument is rawDisplayValue which contains the same text as displayValue but without converting it to lowercase.

Returns JSMethod

Sample

var listProvider = solutionModel.newGlobalMethod('globals', 'function getDataSetForValueList(displayValue, realValue, record, valueListName, findMode, rawDisplayValue) {' +
		'	' +
		'var args = null;' +
		'var query = datasources.db.example_data.employees.createSelect();' +
		'/** @type  {JSDataSet} */' +
		'var result = null;' +
		'query.result.add(query.columns.firstname.concat(' ').concat(query.columns.lastname)).add(query.columns.employeeid);' +
		'if (displayValue == null && realValue == null) {' +
		'  // TODO think about caching this result. can be called often!' +
		'  // return the complete list' +
		'  result = databaseManager.getDataSetByQuery(query,100);' +
		'} else if (displayValue != null) {' +
		'  // TYPE_AHEAD filter call, return a filtered list' +
		'  args = [displayValue + "%", displayValue + "%"]' +
		'  query.result.root.where.add(query.or.add(query.columns.firstname.lower.like(args[0] + '%')).add(query.columns.lastname.lower.like(args[1] + '%')));' +
		'  result = databaseManager.getDataSetByQuery(query,100);' +
		'} else if (realValue != null) {' +
		'  // TODO think about caching this result. can be called often!' +
		'  // real object not found in the current list, return 1 row with display,realvalue that will be added to the current list' +
		'  // dont return a complete list in this mode because that will be added to the list that is already there' +
		'  args = [realValue];' +
		'  query.result.root.where.add(query.columns.employeeid.eq(args[0]));' +
		'  result = databaseManager.getDataSetByQuery(query,1);' +
		'}' +
		'return result;' +
		'}');
var vlist = solutionModel.newValueList('vlist', JSValueList.CUSTOM_VALUES);
vlist.globalMethod = listProvider;

lazyLoading

A property special for NGClient and GlobalValuelist to only query the global valuelist when it is needed. This flag has to be set both on valuelist and in component spec, on the valuelist property.

IMPORTANT: Usage of real & display values is not fully supported with lazy loading. Don't set lazy load if your method returns both real and display values This is because very likely we do need directly the display value for the given real to dispaly its value..
