Hi, I have a quite big form of infopath on sharepoint 2010 and it works fine. I save xml of different sections in a datatable and dynamically binds them on page load. recently I modified a section and there was already a repeating table in it. I have a repeating table with 7 columns in it. 4 columns are comboboxes that have data connections attached. e.g if I select first comboxbox that is binded. then the values of second combo box is filtered. then if i select 2nd the values of 3rd is filtered out. I have used filtering on these maaking them cascading. the problem is strange. Now form is working fine with 3 of the repeating table. and when i add more repeating tables. and put values on it. then the form stucks. e.g I open the form and form loads the xmls and binds the data. when i open .eg 4th, 5th section that contains repeating table it stucks the form. like its not binded. is this the problem with datasource or the xml is not valid? i need urgent solution kindly help me.
