Re: baffling save behavior

Yes, I thought of a possible approach to a test case tonight while doing the kids' activities transportation. If I have time this weekend I'll give it a stab. On Fri, Feb 23, 2018, 21:48 Dominik Stadler wrote: > Hi, > > Your analysis sounds sensible and changing

Re: baffling save behavior

Hi, Your analysis sounds sensible and changing onDocumentWrite() looks ok to me as well from a quick look at the code, we would only add an allocation of the array, which is quit performance-wise compared to all the stuff that happens while saving the document. A reproducing test-case would be

Re: baffling save behavior

I'm finally able to work around the problem by changing XSSFRow.onDocumentWrite() to always copy the current state of the _cells collection to the _row CArray, instead of only when things don't look like they are ordered. There are several cases I've uncovered where the two groups can be the same

Re: baffling save behavior

Re: baffling save behavior

Hi, It might have been the same symptoms which have led Sandeep Tiwari to make a code change that I was reluctant to accept in the branch about charts in XWPF. His explanations were in the line of yours. But I couldn't not accept the idea that such a fundamental feature had been broken. I
