TestLearners widget Random Sampling Error

The evaluation results for the SVM applied to any dataset (e.g. heart_disease.tab) provides ridiculously low CA and other evaluation results, (e.g. for heart_disease.tab, 0.0527, while cross-validation returns .8382). This is not a product of a single dataset. I initially found this massive discrepancy between cross-validation and random sampling results on my own datasets, but found it to still occur in the standard provided datasets as well.

Anze can you take a look at this. Is this the same bug you fixed in r12526?

Yes, this looks like the bug fixed in r12526. Downloading the latest build should solve your problem. (I tested SVM + heart_disease.tab + random sampling and got CA of 0.8275). If the bug is still there after updating, please reopen the ticket.
