IPhone: textview content disappears on table scrolling

Question

Hi,
I have the following problem, if anyone can help: I'm creating a table with textviews inside the cells. When the user scrolls up/down, some of the visible cells loose the textview's content, so no text is displayed for them. This happens randomly, some cells contain the text, some not. The text of the textview is set upon cell creation, so even if the cell is created again after scrolling, the text information exists but is not displayed. This happens only for textviews and not for tetfields or labels. Is this happening to anyone else out there? Any clue?
Thanks in advance,
George

Here is a better, working solution, hope this helps:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
NSMutableSet *visibleViewsSet = [NSMutableSet setWithArray:\[self.tableview visibleCells]];
NSMutableSet *originalVsibleSet = \[visibleViewsSet mutableCopy];
NSMutableSet *cachedSet = self.cachedCells;
//Remove old cached views we already fixed or not currently visible
//We only need to update new cells that are now just visible
\[visibleViewsSet minusSet:cachedSet];
//Reset the cache to contain all current visible cells
self.cachedCells = originalVsibleSet;
for (UITableViewCell *cell in visibleViewsSet) {
\[self workaroundbug:cell];
#pragma mark Workaround
- (void)workaroundbug:(UITableViewCell *)cell {
if (nil != cell) {
UITextView *textView = (UITextView *)\[cell viewWithTag:SNARKYTEXTVIEW];
if (!textView.hidden) {
for (UIView *subview in textView.subviews) {
CGRect bounds = subview.frame;
CGRect cellBounds = cell.bounds;
// subview.backgroundColor = \[UIColor redColor];
if (cell.bounds.size.height > bounds.size.height) {
bounds.size.height = cellBounds.size.height;
subview.frame = bounds;
\[textView setNeedsDisplay];
The reason this works is because, inside of the text view's scroll view lies the REAL text view which may or may not extend to cover the whole area of its enclosing scrollview... its really wierd.... uncomment the line in workaroundbug: to see what I'm talking about...... in any case this solved it for me, hope it works for you.
