FeatureSet in Search widget does not have geometry after setDefinitionExpression applied to the feature layer

PitersonPaulgek — Wed, 07 Dec 2016 23:08:31 GMT

Hi,

We have an issue with geometry.

Case 1 - no issue

We use search widget and features from FeatureSet have geometry

Case 2 - issue

We use search widget, apply setDefinitionExpression and features from FeatureSet have NO geometry.

Piterson,

Can you share some code?

Robert,

Here you are:

///////////////////////////////////////////////////////////////////////////

app.searchWidget = new Search({
enableLabel: false,
enableInfoWindow: false,
map: app.map,
autoSelect: false
}, "");

initialiseSearchWidget();

function initialiseSearchWidget() {

var sources = app.searchWidget.get("sources");

sources.push({
featureLayer: app.featureLayer2,
searchFields: ["Field1", "Field2"],
displayField: "Field1",
exactMatch: false,
name: "featureLayer2",
placeholder: "Some name here",
maxResults: (app.setting.maxSearchResults+1),
maxSuggestions: 5,
infoTemplate: new InfoTemplate("featureLayer2", "featureLayer2 name: ${Field1}</br>Name: ${NAME}"),
enableSuggestions: true,
minCharacters: 0
});

app.searchWidget.startup();

// Function to handle the actual search.
app.search = function (activeSourceIndex, searchValue) { //0-address,1-layer1,2-layer2,3-layer3, 'all'-all
app.searchWidget.activeSourceIndex = activeSourceIndex;
var deferredSearch = app.searchWidget.search(searchValue);
return deferredSearch;
};

app.handleSearchResult = function (response) {

...

HERE : to do zoom to the features based on extent/geometry

Case 1 - no issue

We use search widget and features from FeatureSet have geometry

Case 2 - issue

We use search widget, apply featureLayer2.setDefinitionExpression some place BEFORE app.searchWidget.search(searchValue) and features from FeatureSet have NO geometry.

};

Piterson,

Hmm. When I apply a definition expression to a source layer before the search I don't seem to have any issue, as seen in this sample: (search for "a" and you will only get democrat senators that have a in their names and clicking on the suggestion takes you to the geometry)

As usual, data issue !!

Some feature with shape is NULL.

Robert, thank you for the example code.
