getViewState() throwing error

[svonmiller]

Greetings,

I'm using a treeGrid and trying to save the state. Unless I'm missing something, I should be able to simply say:

var temp = BasicsTreeGrid.getViewState();

But any call to .getViewState() throws the error 'this.header.members is null or not an object in ISC_Grids.js

Am I doing something wrong?

Thanks,
S

This is the code for the treegrid:

isc.TreeGrid.create({
	indentSize:2,
	showConnectors:false,
	animateFolders:false,
	cellPadding:0,
    iconSize:1,
    nodeIcon:"[SKIN]transparent_spacer.gif",
    dataSource:GlobalNavDataSource,
    leaveScrollbarGap:false,
    showHeader:false,
    showOpenIcons:false,
    showClosedIcons:false,
    loadingDataMessage:"Loading menu...",
    loadDataOnDemand:false,
    showHeaderContextMenu:false,
    autoFitData:"vertical",
    autoFitMaxRecords:1000,
    autoFitMaxHeight:1000,
    ID:"BasicsTreeGrid",
    width:panelWidth,
    height:"100%",
    autoFetchData:true,
    initialCriteria: {panel: 1},
    autoDraw:false,
    cellClick: function (record, rowNum, colNum) {
         eval(record.target_page_href);
    }
})

Okay I've determined the problem. getViewState() won't work if the treegrid property showHeader is set to false. This is a problem, as I do not want a header in the tree grid, it's a menu. Is there a workaround for this?

Thanks,

What version are you using?

[svonmiller]

The version is 7.0RC2

[davidj6]

This issue appears to be fixed in the latest 8.0 beta and nightlies. See http://forums.smartclient.com/showthread.php?p=41564 for information on a patch that should work on 7.0 as well:

I'll give it a try.

Thanks!

Yep, that worked. Thanks!
