The getData() method, and therefore the _cm_pre_getData() method, is called each time a web page is built. Once a page has been loaded for the first time and the _cm_pre_getData() method called for the first time, any activities you perform in that page, whether it be pressing a hyperlink or pressing a button, which cause that page to be refreshed will result in repeated calls to getData(). This means that after you have constructed the various SQL component strings the first time you must not allow subsequent calls to _cm_pre_getData() to corrupt those strings.
