Hi, I am building a screen with one Static DataGrid and one Dynamic (data comes through SOAP and I do not know the number of columns or their names in advance). I also get a list of column names in order from another SOAP call.
That Dynamic DataGrid works (converting data from Vector of Objects to ArrayList of Columns). I still have a few problems: 1) I need to implement "Clear" of that Dynamic table. No matter what I tried: arrayColl=null; arrayColl.removeAll(); arrayColl = new ArrayCollection(); myDG.dataProvider=null; myDG.dataProvider=new ArrayCollection(); I am getting NULL reference exception coming from some system code: if (cell.visible)... where cell is null. How can I clear that dynamic DG ? full exception stack: TypeError: Error #1009: Cannot access a property or method of a null object reference. at spark.components.gridClasses::GridLayout/updateTypicalCellSizes() at spark.components.gridClasses::GridLayout/measure() at spark.components.supportClasses::GroupBase/measure() at mx.core::UIComponent/measureSizes() at mx.core::UIComponent/validateSize() at spark.components::Group/validateSize() at mx.managers::LayoutManager/validateSize() at mx.managers::LayoutManager/doPhasedInstantiation() at mx.managers::LayoutManager/doPhasedInstantiationCallback() 2) It seems that by default that Dynamic DG puts columns in alphabetical order, which is of course not what I need. Any way to disable that or fix somehow? 3) I need to show 2 DGs on the screen, and the second of them is Dynamic, and allow user to resize them vertically to be able to see more in static or dynamic DG. I put them in VDividedBox (and set height of both DG and container to 100%). It split the screen vertically 50:50, but still there is no draggable in between, so can't resize. Any help is very appreciated. TIA, Oleg.
