Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the example, affect the Fund's performance. During its most recent fiscal year, the Fund's portfolio turnover rate was 38% of the average value of its portfolio.

Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses (including one year of capped expenses in each period) remain the same.

Investment Strategy, Heading	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGY
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund invests at least 80% of its net assets in securities of small companies. For purposes of this policy, a small company is defined as having a market capitalization of less than $2.5 billion at the time of purchase. The Fund seeks capital appreciation by investing mainly in common stocks of small companies that the Adviser believes have strong long-term fundamentals, superior capital appreciation potential and attractive valuations. Through the consistent execution of a fundamental bottoms-up investment process, which includes an effort to understand a company's intrinsic or fair value, the Adviser expects to identify a diversified universe of small companies which trade at a discount to their estimated or intrinsic fair values. As such, the Adviser seeks to mitigate company specific risk by limiting position sizes to 3% of the Fund's total assets at market value. The Adviser will sell a security when it reaches the Adviser's estimate of its fair value or when information about a security invalidates the Adviser's basis for making the investment. The Adviser may also sell a security when its market capitalization exceeds $3 billion, although the Fund may hold securities whose market capitalization exceeds $3 billion if it is a constituent in a small cap benchmark. Additionally, the Adviser may also sell securities in order to maintain the 3% limit on position sizes or when exposure to a sector exceeds the Adviser's sector weight rules. The Fund is broadly diversified and seeks to create value primarily through favorable stock selection.
Risk, Heading	rr_RiskHeading	PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk, Narrative	rr_RiskNarrativeTextBlock	As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. A FUND SHARE IS NOT A BANK DEPOSIT AND IT IS NOT INSURED OR GUARANTEED BY THE FDIC, OR ANY GOVERNMENT AGENCY. The principal risk factors affecting shareholders' investments in the Fund are set forth below. Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. The Fund is also subject to the risk that small capitalization stocks may underperform other segments of the equity market or the equity market as a whole. The small-capitalization companies that the Fund invests in may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these small-sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small-cap stocks may be more volatile than those of larger companies. These securities may be traded over-the-counter or listed on an exchange.

[1] Champlain Investment Partners, LLC (the "Adviser") has contractually agreed to reduce fees and reimburse expenses in order to keep Total Annual Fund Operating Expenses After Fee Reductions and/or Expense Reimbursements (excluding interest, taxes, brokerage commissions, acquired fund fees and expenses and extraordinary expenses (collectively, "excluded expenses")) from exceeding 1.40% of the Fund's Advisor Class Shares' average daily net assets until November 30, 2012. In addition, if at any point it becomes unnecessary for the Adviser to reduce fees or make expense reimbursements, the Adviser may retain the difference between the Total Annual Fund Operating Expenses (not including excluded expenses) and 1.40% to recover all or a portion of its prior fee reductions or expense reimbursements made during the preceding three-year period during which this agreement (or any prior agreement) was in place. This Agreement may be terminated: (i) by the Board, for any reason at any time; or (ii) by the Adviser, upon ninety (90) days' prior written notice to the Trust, effective as of the close of business on November 30, 2012.
