I still do not understand your plan to put a symbol to other symbol info container... As I understand, each Symbol (Picture, Text, Composite ...) is tied to the Map and can not exist without it. During symbol initialization, graphic geometry is converted to screen coordinates and the convertion result is the place where symbol must be shown in FLEX application -> in your case TextSymbol has no own Graphic -> has no own Geometry -> as a result can not be shown. Maybe I'm wrong, but to me it all seems so. In API reference for com.esri.ags.symbols.InfoSymbol a lot of links to samples. Based on samples: simple app - add graphic to map with one text attribute ("myTitle"). This attribute is shown in InfoSymbol's container as Label.

text parameter The text string to display. or textAttribute property The string representing the attribute of the graphic that should populate the "text" content. or textFunction property The text function allows for the text of the text symbol to be dynamically picked - for example based on attributes or position of the graphic. Sorry, but I did not found any part of code, what initialize text in your sample 😞 - only format and angle Plus some ActionScript code that initializes text, something like this: var txtFormat:TextFormat = new TextFormat(textFont.selectedItem.font, numTextSize.value, cpText.selectedColor, bold.selected, italic.selected, underline.selected); textSymbol.textFormat = txtFormat; textSymbol.angle = numTextRotation.value; graphic.symbol = textSymbol; // graphic obj takes geometry as a parameter ...

From API reference com.esri.ags.layers.supportClasses.LOD Levels of detail (LOD) for a TiledMapServiceLayer. Each LOD corresponds to a map at a given scale or resolution. Both resolution and scale are required fields. LOD's are automatically sorted based on scale, so setting level isn't necessary. ... here is 20 levels.

working with table/layer - DetailsTask; working with MapService - AllDetails ... ... anywhere your target must be LayerDetails - it holds all information about layer/table types (each type is FeatureType) and layer/table fields (each field is Filed - > with public property domain).
