Grid View Refresh - gwt core error

[jonas sabu]

Hi all,

I am using a TreeGrid with a Grid View that i wanted to refresh every time i change a row. To do that i found the GridView.refresh() method that does exactly what i want. Only problem is when i do the refresh with any tree node parent expanded, next time I try to collapse that parent by double clicking it it gives this error:

And it doesnt change the arrow in the selected row to expand:
25474

Thanks in advance hope anyone can help me. I'm running ext gwt 2.2.0.

Are you still facing problems?

I'm seeing something similar within my own code sometimes.

[mikedonovan]

i have existing code and am using gxt 2.2.3 today.

i found that with treegrid and all default selection models on a expanded tree:

1. i expand, collapse a node by clicking on the icon for coll/exp
2. i then click on the icon to expand again
3. it doesnt change
4. i double click and it still stays the same icon, however expansion occurs
5. i doulbe click to collapse and i get that exception you have

NOTE: the row isnt selected on the 1st expand/collapse. but on the next expand the row becomes selected and its like when i click on the expand icon it doesnt expand, however the row selected

i use gridview refresh after the model is available as i calculate heights and ask for a refresh after setting dimensions. used to work in the old gxt code.

any ideas ?

I still have the same problem :( don't know how to solve this... a workaround would be cool

[sven]

Can anybody please post a fully working testcase implementing entrypoint for this? Or can somebody give me the steps to reproduce this here: http://www.sencha.com/examples/#basictreegrid

[jonas sabu]

Ok i made a simple test and got that error again, here it is:

TreeStore<ModelData> store = new TreeStore<ModelData>();
TreeGrid<ModelData> tree = new TreeGrid<ModelData>(store, cm);

BaseTreeModel n1 = new BaseTreeModel();
n1.set("name","num1");
BaseTreeModel n11 = new BaseTreeModel();
n11.set("name","num11");
n1.add(n11);

BaseTreeModel n2 = new BaseTreeModel();
n2.set("name","num2");

BaseTreeModel n3 = new BaseTreeModel();
n3.set("name","num3");
BaseTreeModel n33 = new BaseTreeModel();
n33.set("name","num33");
n3.add(n33);

store.add(n1,true);
store.add(n2,true);
store.add(n3,true);

Then when i click a button on the UI, i Dispatch.get().dispatch(EVENT_XXX);

That EVENT_XXX does the following:
tree.getView().refresh(true);

After that the same error reported here occurs.

That is a already known issue. I will report back here once that is fixed in SVN.


UPDATE:

This is already fixed in SVN now

[tomasz.lewandowski]

I have the same problem using gxt 2.2.4. Should the problem be already fixed in 2.2.4 ?
