------- Additional comments from [email protected] Fri Nov 13 12:18:52 +0000 2009 ------- Some observations of the way OOMath handles math formulas. One can notice two things. 1) OOMath incorrectrly interprets the MathML code with double subscripts. 2) Having created in OOMath the formula with double subscripts one can save it as MathML and reopen it correctily. How could it be? The answer is - OOMath additionally saves the formula in it's internal format! Look at attachment 66094 (http://www.openoffice.org/nonav/issues/ showattachment.cgi/66094/content_corrected.mml). It is the formula with double subscripts, corrected and saved in OOMath. You could open it in OOMath and it displayed it correctly. I've checked the MathML in this file (and reindented it for better readability) - the MathML is correct. But this file has an additional string: <math:annotation math:encoding="StarMath 5.0">R_k ="∫"_{t_k}^{t_{k + 1}} y { \( t \)} cdot s_{r e f} { \( t \)} d t</math:annotation> It is the code of the formula in the OOMath format. Having deleted this string I obtained the file you can see in attachment 66095 (http://www.openoffice.org/nonav/issues/showattachment.cgi/66095/ content_wo_oomath.mml) OOMath can't open it correctly! So, some conclusions about the way OOMath handles formulas: 1) OOMath saves correct MathML code. 2) Along with the MathML, it saves an additional string with the formula in it's own format. 3) While opening document, OOMath look up the string in it's own format. Having found it OOMath uses it and completely ignores the MathML code. 4) If the file have no the string in OOMath's format, OOMath had to use MathML code, which it can't interpret correctly. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
