[4.2] Missing method removeRange in Ext.util.LruCache class

[kerbo]

When testing 4.2, my application tried to do a removeAll on an empty store and hit this error

Uncaught TypeError: Object [object Object] has no method 'removeRange'

if (removeRange) {
data.removeRange(records.start, removeCount);
} 

at row 72223 in ext-all-debug

data is a "Ext.util.LruCache" class and sure enough, this method doesn't exist on the class.

Can you outline the use case for wanting to clear a buffered store?

[kerbo]

I have a set of search filters for the grid. When the person clears the filters, I empty the grid.

I don't check to see if the grid is already empty. I could, but his code has worked since 3.x days.

I added the grid to use a buffered store in 4.1.

We are also getting the error of removeRange not being a function in store when using removeAll to delete all the records of an infinite grid. Any clues on that?

Thanks.

Did this problem get classified as a bug?

Same problem. Tried the following code - no errors but doesn't do anything either:

this.store.remove(this.store.getRange(0, this.store.getCount()));

[fshnet]

Same problem here as well
Any workarounds for this?
Is there an alternative way to empty a grid panel?

[kerbo]

My workaround is to load the store with an empty array

store.loadData([]);

This will clear the store but you won't get any events.

and.... same problem for me.

I have a grid that loads search results. When the user changes their query I do a store.removeAll() followed by a store.loadPage(1). Everything worked fine until I set buffered:true in an effort to switch from ordinary paging to infinite scrolling.

ahh... the joys... a hiccup at ever step

store.data.clear()
