[CLOSED] Conflict ResourceManager & ScriptManager using ReportViewer

[egvt]

Hello!, good afternoon, i'm trying to show a report with several subreports using reportviewer control into a masterpage, but when running the application using some control ext.net or just adding the ResourceManager, then get this error:

Error: Sys.WebForms.PageRequestManagerServerErrorExceptio n: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request..

If I remove the ScriptManager no have error, but I can not remove because it uses the reportviewer, if I remove the ResourceManager does not show the report and sends the error. I tested the report with any source, so it is not relevant(the source of report), you can reproduce with any dataset or datasource.
