Description goneri 2010-09-02 10:31:09 UTC

Hello,

I hope editing is the correct Subcomponent for this bug.

The attach form document is very slow to open (> 1 minute). If we turn "Designer
mode" we avoid the problem because oowriter don't compute the order of the
formular of the document (for the [TAB] key).

If we turn this research off, the document get loaded as quickly as a normal
.odt document. We attached the patch we used to turn this off.

This is a regression since OpenOffice 2.4. We can reproduce the issue with any
3.0 release on Linux or Windows.

Best regards

The workaround

We think it's a race condition. When the "find first form field" is launch, a 
message is send to the main thread. When the message is managed, at the same 
time, another thread load and analyse the document. The inter-lock between this 
two thread generate the delay. I think so...

Did you already tray with OOo 3.2.1 release or 3.3 pre-release OOO330m6?
If the problem still occurs with these builds, please attach a sample document
which exposes the problem. Thank you for supporting us!

MRU->OD: please have a look, where the problem is. Loading the document takes
normal speed,after the view has been built it needs almost a minute before
Writer becomes responsive.
The document consists of several Form-Controls in tables.
Maybe the problem is related to issue 59557.
