-------------------------------

[~zhongjian], you want to double check the JS part?  Java part is no problem.

And we'd better have a coding convention in the JS too.

> currently, the dimensions or measures of model maybe have null column.
> like this: 
> u'dimensions': [{u'table': u'TEST.KYLIN_CAL_DT_KKS', u'columns': [u'CAL_DT', u'YEAR_BEG_DT', u'QTR_BEG_DT', None, u'DAY_OF_CAL_ID_KKS']}]
> which could be produced by the following steps:
> 1. rename the hive column in model dimensions or measures.
> 2. reload the hive table.
> 3. don't remove the null column because of carelessness and update the model.
> 4 edit the model again and could not select the dimensions or measures.
