[FIXED] GRID restore state bug

[aart.de.vries]

When hidding a column from the grid, that was previously already saved in the grid's state as the "sortField", GXT fails to restore the grid when next the application is started.

I fixed this by overriding Grid. In the overridden class I overwrote applyState(), with the following code (note: I marked my additions):
@Override
protected void applyState(Map<String, Object> state) {

super.applyState(state);
if(isStateful())

for(ColumnConfig c: cm.getColumns()) {

String id = c.getId();
if(state.containsKey("hidden" + id)) {

if(id.equals((String)state.get("sortField"))) //Added

state.remove("sortField"); //Added

c.setHidden((Boolean)state.get("hidden" + id));

}
if(state.containsKey("width" + id))

c.setWidth((Integer)state.get("width" + id));

String sortField = (String)state.get("sortField");
if(store.getLoader() == null && sortField != null) {

String sortDir = (String)state.get("sortDir");
SortDir dir = SortDir.findDir(sortDir);
store.sort(sortField, dir);

}
}

}

This works for me. There are probably other ways to prevent this bug from showing (for example by adding checks on the store's sort method. Either way, I hope that this is fixed in a next release.

Hi,
I have given "stateful: true," in the GridPanel. I can hide columns and save it in cookies. I would like to have a restore button, clicking on which should show me the default selected columns. How can i call applyState function to restore the hidden columns? Can anyone give me an example?
