Hi All,
When we upgrade our system to CRM 9.0 , we meet some difficult issue for web resource.
Background : 1. We set [Use legacy form rendering] to No. 
2. As there many section on form page , we set some section not expend by default . 
3. In this section we will display our web resource. And for some reason, we need get some info from sections when CRM page on load.
Description:
Usually page should not be initialize until the section be expand. But the page initial when page load, as we called "control.getControlType","control.getName","control.getObject" function in form load event.
And when the page initialed, the window width value was 0. This will causing some page problems.
Other:
1.If set [Use legacy form rendering] to Yes, web resource will not be initialize until the section be expand.
2. If set section expand by default, when web resource initial, window can get the correct width value.
3. If not call above functions, the page will initial when the section be expand. This kind page will display well.
My question:
The above solution does not meet my needs, anyone has other ideas ?
Anyone knew what happened in getControlType,getName,getObject function for control ? Why these function will trigger web resource initial? Is this a knew issue?
