Recovering OWB mapping with map_reconstruct.tcl script

There is another case for using MAP_RECOSTRUCT.tcl script (except using for export/import mappings between environments). Sometime dueto OWB bug/OWB repository corruption it is impossible to open map for editing in Design Center (in my practice this happened twice as I remember). The problem usually in single operator or attribute.
In this case we can use MAP_RECOSTRUCT.tcl script for identification problem object in mapping - run this script against such corrupted mappings and script outputs in generated file error message which allow identify problem object. Release 0.0.2 of MAP_RECOSTRUCT.tcl script already contains code which output into target file comments if error raised (and script won't stop!) during extraction properties for attribute - so it is possible to get working copy of corrupted mapping...
