Hi! Our company has been using sharepoint since 2007 and now, we have migrated to 2010. We are heavy users of sharepoint since most of our process is built in sharepoint workflow and infopath client. The direction of our company is towards mobility to our account mangers, sales representative and marketing. since we  are already using infopath and sharepoint workflow to meet the day to day operations of the company, we are hoping to still use our existing technology to mobility. We purchased ipads for our employees and bought the shareplus application to bridge the gap between pc - sharepoint - infopath -ipad. We are currently in the process of ipad remediation by converting our infopath forms to infopath web-based forms. We already know the limitation between a client app and a browser based app so i'll spare you the details. I guess the issue here, during our testing we were able to identify 2 major issues in using shareplus. 

1. The lookup limitation issue- one of the issue in sharepoint form libraries is the lookup issue when lookup columns in a view is more than 8 lookup columns. There are 2 ways to solve this, the first one is to adjust the throttle service in central admin. The second one is to maintain equal or less than 8 lookup columns in a view( lookup columns are lookup type, person or group type and workflow column name). We were able to solve this by following the second solution. However, in shareplus, when we try to access the same form libraries, we still get this error compared in viewing it on a browser( safari or native shareplus browser). My theory here is that when shareplus pulls data from the library, it automatically pulls all the columns/fields inside that library, making the view with less than 8 lookup columns useless. Even if it renders the correct filtering (defined in the view) it still throws this server error.

2. Attachment in infopath browser based forms. - as you know shareplus has a capability to store documents inside shareplus app "local files". User can use this file to upload it in sharepoint libraries. In this way, shareplus wa able to eliminate apple's restriction in file browsing. However, when an infopath form is opened inside the native browser of shareplus, we cannot attach a file from the local files of shareplus. We can only attach either existing pictures or a new picture. the default shareplus browser doesn't inherit the capability of the local files saving feature.

Given these 2 major issues that we are encountering, do we have a solution for this? If none, will infragistics look for a solution and release it on the next version? Hoping for your fast response. Thanks.
